Chocolate Marshmallow Hearts Recipe

By Callie

The first time I made chocolate marshmallow hearts, I was trying to recreate something Emily had seen at a Valentine’s Day market and came home talking about at considerable length. Heart-shaped chocolate candies with a marshmallow inside. Not a caramel center, not a truffle ganache, not a fondant – a marshmallow. Soft, pillowy, sweet. Inside a shell of chocolate that snapped when you bit through it. She described them three times in different ways to make sure I had the full picture.

The silicone heart mold technique turned out to be the key to making these at home without any professional equipment or skill. You pipe a thin layer of chocolate into each cavity, spread it with a brush to coat the walls completely, chill for 3 minutes to set the shell, place a mini marshmallow inside, cover with more chocolate to seal, and chill again. That’s the whole process. The chocolate shell contracts very slightly as it sets in the cold, which produces the clean release from the silicone mold that makes these look like they were made in a shop. No candy thermometer, no tempering, no difficult technique.

Emily helped with every step when we made our first batch together – the piping, the brush-coating, the marshmallow placement (which she took very seriously, centering each one with great deliberation), the sealing, the drizzle decoration. She kept one plain to eat immediately after unmolding and packaged the rest in a small box with tissue paper for her teacher. The teacher response was enthusiastic enough that the following year Emily asked to make two boxes – one for the teacher and one for her best friend. These are now a February tradition.

The technique is also completely seasonal-adaptable: the same method with different shaped molds produces Easter eggs, Christmas trees, Halloween pumpkins, or any other shape with an appropriate holiday mold. For another simple molded chocolate project that uses the same technique without a marshmallow insert, the Valentine’s Day Chocolate Bark is an even simpler melted-chocolate confection that pairs beautifully with these hearts in a gift box.

Speed Hacks – Chocolate Marshmallow Hearts Ready In 40 Minutes:

  • Melt the chocolate in a zip-top bag or piping bag rather than a bowl – you can pipe directly from the bag with no transfer step and no bowl to clean
  • Set up the mold on a small tray that fits in the refrigerator before you start – the tray makes moving the mold in and out of the fridge safe and efficient
  • Use a small food-safe pastry brush or even a clean finger to spread the chocolate into the mold walls – a brush produces the most even coating in less time
  • Work with one mold tray at a time and keep the second batch of chocolate warm by setting the piping bag in a warm cup of water between uses
  • The 3-minute shell chill and 10-minute seal chill can be done in the freezer for faster setting – 2 minutes and 6 minutes respectively

Why You Will Love These Chocolate Marshmallow Hearts

  • The chocolate-marshmallow combination is a specifically satisfying textural contrast that few other confections produce. The snap of a chocolate shell giving way to the soft, airy, yielding marshmallow inside produces two completely different textures in a single bite – firm and smooth outside, pillow-soft and sweet inside. This contrast is what makes the combination more interesting to eat than a solid chocolate piece or a plain marshmallow. The experience of biting through the shell and hitting the marshmallow is genuinely surprising and pleasant in a way that makes people want another one immediately.
  • Two ingredients, 40 minutes, and a result that looks and feels like specialty shop confectionery. Melting chocolate and mini marshmallows. A silicone mold. A few minutes in the refrigerator. The finished hearts have a smooth, professional appearance because silicone molds produce perfectly smooth, evenly formed chocolate surfaces that look nothing like hand-formed candy. The gap between effort and apparent skill is dramatic, which is what makes these such an effective gift.
  • The silicone mold technique produces a clean, professional release without any special skills. Chocolate contracts very slightly as it cools, which creates a natural separation from the mold walls. Silicone’s flexibility means you can gently press the back of each cavity to pop the candy free with no sticking, no prying, no damage to the surface. This is different from metal or plastic molds where residual chocolate sticking at the edges is common. Silicone heart molds are inexpensive and available everywhere baking supplies are sold.
  • The decorative drizzle step is optional but takes 5 minutes and transforms good-looking hearts into gift-shop-caliber ones. White chocolate tinted with pink candy coloring and drizzled over the set dark or milk chocolate hearts produces a pink-and-brown or pink-and-ivory visual that is immediately recognizable as deliberate and professionally executed. It’s the specific finishing touch that communicates “I made this for you specifically” rather than “I made candy.”
  • Completely customizable for any holiday or occasion by changing only the mold shape and the drizzle color. Heart shapes and pink drizzle for Valentine’s Day. Egg shapes and pastel drizzle for Easter. Tree shapes and green drizzle for Christmas. Pumpkin shapes and orange drizzle for Halloween. The two-ingredient core recipe stays identical – the mold and the decoration change the occasion.
  • The recipe is naturally gluten-free with standard ingredients. Melting chocolate and mini marshmallows contain no gluten. For guests with celiac disease or gluten sensitivity, check that your specific chocolate brand and marshmallow brand are certified gluten-free and processed in gluten-free facilities. Most standard brands of both are inherently gluten-free in formulation.
  • They store for up to two weeks at room temperature – the longest-keeping confection in the Valentine’s category. The chocolate shell acts as a preservative barrier that keeps the marshmallow soft and fresh inside, protected from air and humidity. This two-week shelf life at room temperature makes them practical for making ahead and gifting in a way that fresh fruit dipped in chocolate or cream-filled confections are not.
  • The gifting presentation – hearts in a small box with mini cupcake liner cups – looks like it took significantly more effort than it did. A box of six chocolate marshmallow hearts, each in its own mini cupcake liner, arranged in tissue paper inside a small gift box with a ribbon – this is the presentation that costs about $8 total in ingredients and packaging and looks like a $25 artisan confectionery gift. The heart shape, the chocolate shell, the careful arrangement – all of these communicate thought and effort even when the total active work was 40 minutes.

Chocolate Marshmallow Hearts Ingredients

The Full Ingredient List

  • 2 cups (about 340g / 12 oz) melting chocolate, chocolate chips (for this application), or candy melts
  • 30 mini marshmallows (one per heart)
  • 1-2 teaspoons vegetable oil or coconut oil if needed to thin the chocolate

For the decorative drizzle (optional):

  • 1/3 cup (about 55g) white melting chocolate or white candy melts
  • Pink candy coloring (oil-based or specially formulated for chocolate – see notes)

Equipment needed: Silicone heart molds (24-cavity or 30-cavity mini heart mold, or any size that accommodates a single mini marshmallow per cavity), small food-safe pastry brush, piping bag or zip-top plastic bag

Ingredient Notes And Substitutions

Melting chocolate vs candy melts vs regular chocolate bars – what works best here: This recipe specifically uses a mold-coating technique where the chocolate needs to coat the inside walls of each cavity smoothly and then release cleanly after setting. For this application, candy melts (Wilton, Ghirardelli Melting Wafers, Merckens) are actually the best choice – they’re specifically formulated for mold coating, melt to a smooth, fluid consistency at low temperature, release from silicone cleanly, and produce a professional-looking shell. Quality chocolate bars (Ghirardelli, Callebaut) work but may need oil added to thin them to the right coating consistency. Standard chocolate chips work in this application because the chocolate doesn’t need to stay perfectly glossy and snappy the way it would in a plated dessert – it just needs to melt smoothly and set firmly, which chips do adequately with oil added. For the best-looking, easiest-to-work-with result, use chocolate melting wafers.

Mini marshmallows – size matters: Regular mini marshmallows (the standard bag size found in any grocery store baking aisle) are the right size for a standard small silicone heart cavity – they fit comfortably with chocolate surrounding them on all sides without being so large they break through the shell. Jumbo marshmallows cut in half work if mini aren’t available, but the cut surface can absorb some chocolate and make the interior slightly less clean-looking. The smallest molds may not accommodate even a standard mini marshmallow and would need a mini-mini marshmallow or a small piece of marshmallow. Test your mold and marshmallow combination before starting.

Pink candy coloring vs regular food coloring for the drizzle: Regular water-based food coloring (the standard squeeze bottles) will cause white chocolate or candy melts to seize when added – water and chocolate are incompatible and even a small amount of water causes the fat emulsion in melted chocolate to break into a thick, grainy mass. Always use oil-based candy coloring or candy-specific food coloring (sold as “Chefmaster Candy Colors,” “Wilton Candy Colors,” or similar) for tinting white chocolate or candy melts. These are oil-dispersible rather than water-dispersible and incorporate smoothly into melted chocolate without causing seizing. A small bottle costs about $3-5 and is available at most craft stores and online.

The oil-for-thinning addition: If your melted chocolate or candy melts are too thick to pipe smoothly through a small tip – the chocolate drips in globs rather than a steady stream – add 1-2 teaspoons of vegetable oil (flavorless) or coconut oil (adds a very slight coconut note) to the warm chocolate and stir until incorporated. The oil lowers the viscosity and produces a more fluid chocolate that pipes cleanly. Add 1 teaspoon first, stir thoroughly, assess; add a second teaspoon only if needed. Too much oil produces chocolate that’s too thin and runny to coat the mold walls without dripping out.

Callie’s Kitchen Note: Emily’s marshmallow centering is genuinely painstaking. She places each marshmallow, steps back to assess, adjusts if necessary, places the next one, steps back again. For a 30-cavity mold this takes approximately 12 minutes with full commentary throughout. I now give her the mold to manage completely while I handle the chocolate melting and piping. She treats the marshmallow placement as her specific artistic contribution to the finished product and takes feedback on off-center marshmallows very seriously. The result is beautifully centered marshmallows in every heart. Team effort. I mention this because involving a child in the step that’s genuinely precise and deliberate, rather than just “stir this for me,” produces a level of engagement and investment that makes the whole baking session better for everyone.

How To Make Chocolate Marshmallow Hearts

The Full Timeline

Active hands-on time: approximately 25-30 minutes. Refrigerator setting time: about 13 minutes total (3 minutes for shell, 10 minutes for seal). Total elapsed time: about 40-45 minutes. The refrigerator time is entirely passive. This is genuinely achievable in a single late-afternoon session with a child’s help or during any 45-minute window you have available.

1- Set Up The Mold And Prepare The Workspace

Place the silicone heart mold on a small, flat baking sheet or tray that fits in your refrigerator. The tray allows you to move the mold in and out of the refrigerator without disturbing the individual cavities, which can be difficult to handle safely without a tray underneath. Have the mini marshmallows in a small bowl nearby. Have the food-safe pastry brush clean and dry. Set up the piping bag or zip-top bag for the chocolate. The workspace setup matters for this recipe because once the chocolate is melted, you’re working efficiently against its cooling time.

2- Melt The Chocolate

Combine the 2 cups of melting chocolate in a piping bag or a sturdy zip-top bag. Microwave in the bag at 50% power for 1 minute. Remove, massage the bag gently to distribute heat and check the melt status, and microwave again in 10-second intervals at 50% power, massaging between each, until the chocolate is fully melted and completely smooth when massaged between your fingers through the bag. This takes 2-4 minutes total at 50% power. The 50% power prevents the chocolate from overheating and seizing. Once melted, twist the top of the bag closed and snip a very small corner – 1/8 inch (3mm) – for a controlled piping tip.

If the chocolate seems thick or doesn’t flow in a thin, smooth stream from the snipped corner, add 1 teaspoon of vegetable oil through the top of the bag, massage to incorporate, and re-assess. The chocolate should flow in a thin, controlled stream that allows precise piping into the mold cavities.

3- Pipe And Brush The Chocolate Shells

Pipe approximately 1 teaspoon of melted chocolate into the bottom of each heart cavity. Using the food-safe pastry brush, quickly spread the chocolate up the sides of each cavity, ensuring complete coverage with no gaps or thin spots. The shell needs to be thick enough to hold a marshmallow and seal properly without cracking – aim for a coating thickness of about 1-2mm throughout. Thin spots at the bottom or sides may crack when the candy is unmolded or bitten into.

Work through all 30 cavities efficiently – the chocolate in the first cavities will begin setting while you work through the later ones, which is fine. Once all cavities are coated, transfer the tray to the refrigerator for 3 minutes until the chocolate shells are set but still slightly tacky at the rim (the tacky rim will bond better with the sealing layer of chocolate).

Why The Shell Must Be Fully Set Before The Marshmallow Goes In

Placing a marshmallow in an un-set chocolate shell allows the marshmallow to sink into the soft chocolate, disrupting the even coating. The marshmallow’s weight and contact with warm, soft chocolate can push through thin spots and create holes in the shell that will show on the finished candy’s surface. Three minutes in the refrigerator is enough time for the chocolate to set to a firm, solid shell that supports the marshmallow on top of it rather than having the marshmallow sink into it. Check that the shell is firm by touching a corner of one cavity – it should feel solid and cool to the touch, not yielding.

4- Place The Marshmallows

Remove the tray from the refrigerator. Place one mini marshmallow in each cavity, pressing it gently onto the set chocolate shell so it sits flat and centered in the cavity. The marshmallow should be positioned toward the center of the cavity rather than pushed all the way down to the bottom – leaving some space between the marshmallow bottom and the chocolate shell bottom allows the sealing chocolate to flow under it and around it for complete encapsulation. Press gently enough that the marshmallow stays in place without being compressed flat.

5- Seal The Hearts

Pipe melted chocolate over each marshmallow to seal – pipe into the cavity around the marshmallow first (sides), then over the top, filling the cavity level with the rim of the mold. Tap the tray on the counter 3-4 times firmly to settle the chocolate and remove air bubbles trapped between the marshmallow and the sealing chocolate. The tapping motion should be decisive rather than gentle – a firm tap from about 2 inches above a hard surface. If the chocolate level settles below the rim after tapping, add a small amount more to fill flush. A fill that’s above the rim will produce a flat bottom on the finished candy (which stands better on a plate); a fill slightly below the rim produces a slight dome on the bottom.

Return the tray to the refrigerator for 10 minutes until the chocolate is fully set throughout and firm to the touch. If you’re in a hurry, 6 minutes in the freezer produces the same result.

Callie’s Kitchen Note: The tapping step is more important than it sounds. The first time I made these without tapping, several of the finished hearts had visible air pockets in the sealing chocolate – areas where the chocolate had bridged over an air bubble rather than flowing down to fill it. When bitten into, these air pockets meant the marshmallow wasn’t fully encased and sometimes the filling shifted toward one side during eating. The firm tap-on-the-counter method gets the chocolate to flow around all sides of the marshmallow rather than sitting over it. Four good firm taps from about 2 inches up – you want to hear the tray hit the counter, not a gentle pat. The difference in the finished candy’s appearance and interior consistency is immediately visible.

6- Unmold The Hearts

Once fully set, flip the silicone mold upside down over a piece of parchment paper. Flex the silicone gently from the back of each cavity using your thumbs to press the chocolate heart free. The chocolate should release cleanly and completely from the silicone, landing smooth-side-up on the parchment. If a heart resists releasing, return the mold to the refrigerator for another 5 minutes – the chocolate may not be fully set at the center, or the temperature differential between the cold chocolate and the room hasn’t been sufficient for clean release. Never force a resistant heart – forcing damages the shell.

Set each released heart smooth-side-up on the parchment paper. The bottom of the heart (the flat sealing surface) should now be facing up, and the smooth molded surface should be the visible, display face.

7- The Decorative Drizzle (Optional)

Melt the 1/3 cup of white chocolate or white candy melts in a small piping bag or zip-top bag using the same 50% microwave power method. Add a small amount of oil-based pink candy coloring and massage to incorporate until the chocolate is evenly tinted – a pale blush pink reads as elegant; a vivid hot pink reads as playful. Both are beautiful for Valentine’s Day; choose based on the recipient and occasion.

Drizzle the pink-tinted white chocolate over the set hearts in a back-and-forth motion using the snipped-corner bag – a slow, steady wave from left to right, working down the row of hearts. The drizzle should create thin, slightly irregular lines rather than thick globs. Allow the drizzle to partially set at room temperature for 5 minutes, then refrigerate briefly for the final set. Transfer each finished heart to a mini cupcake liner for packaging.

Callie’s Kitchen Note: Emily’s teacher’s response to the first box of these was to bring them into class the next day and share them, which produced the specific result that several classmates asked Emily what they were and whether she made them. She confirmed that yes, she helped make them, and had to provide a certain amount of explanation about the process (marshmallow inside, chocolate outside, silicone mold). The result was that she became the class authority on how chocolate marshmallow hearts are made, which she found more satisfying than I expected. I mention this because “makes a child the expert on something” is underrated as a criterion for choosing what to bake together. These cleared that bar very effectively.

Common Mistakes To Avoid

Overfilling The Mold Cavities

Chocolate piped above the rim of the mold cavity doesn’t produce a heart with a clean, flat bottom – it produces a heart with a protruding rim that makes the candy wobble on a flat surface and doesn’t release as cleanly from the mold. Fill to the rim for a flat-bottomed heart that sits stable and releases cleanly. The tap-on-the-counter step settles any fill that’s slightly above the rim back down to level.

Using Water-Based Food Coloring For The White Chocolate Drizzle

Already covered in the ingredient notes but the consequences are severe enough to repeat: water-based food coloring added to melted white chocolate or candy melts causes immediate seizing – the chocolate goes from smooth and fluid to a thick, grainy, unusable mass in seconds. This is not fixable. Use only oil-based candy coloring for tinting chocolate. One small bottle is inexpensive and is the correct tool for this specific application.

Not Waiting For The Shell To Set Before Adding The Marshmallow

A marshmallow placed in a soft, un-set chocolate shell will sink, tip, or push through thin areas of the coating. The 3-minute refrigerator chill is essential for a firmly set shell that supports the marshmallow’s weight and contact. The shell should feel firm and cold to a light fingertip touch before the marshmallow goes in. If you’re rushing and skip this step, most hearts will still work – but a percentage will have shifted marshmallows or broken shells that show on the finished candy.

Skipping The Tapping Step

Already covered in the Kitchen Note. Air pockets in the sealing chocolate produce hearts with uneven interiors where the marshmallow isn’t fully encased. Four firm taps from 2 inches up costs 10 seconds and eliminates this problem. Do it every time.

Forcing Hearts Out Of The Mold Before Fully Set

Rushing the final set and forcing the hearts out while the chocolate is still soft produces hearts with fingerprint impressions, bent or cracked shells, and potentially marshmallow visible at the break point. The 10-minute refrigerator chill (or 6 in the freezer) is the minimum. If any cavity resists gentle flexing of the silicone, wait 5 more minutes. Clean release is guaranteed by proper setting; forcing is guaranteed by impatience and produces damaged hearts.

Callie’s Kitchen Note: I’ve made these in dark chocolate, milk chocolate, and white chocolate shells. My personal preference ranking: dark chocolate shell with milk chocolate drizzle (most sophisticated, the bitter-sweet dark shell against the sweet marshmallow is genuinely excellent), milk chocolate shell with pink drizzle (most classic Valentine’s candy aesthetic and the version Emily prefers), white chocolate shell with dark drizzle (most visually striking, the ivory and dark brown contrast is beautiful, and the sweet white chocolate against the marshmallow is the sweetest version). For a gift box that contains all three: unmold and arrange one row of each in a box with tissue paper lining for a variety that shows the three contrasting color combinations together. It looks deliberate and sophisticated even though the work was identical across all three – you just changed the chocolate type.

Storage

Room temperature: Store chocolate marshmallow hearts in an airtight container at room temperature for up to 2 weeks. The chocolate shell protects the marshmallow from moisture and air, keeping it soft and fresh inside. Keep away from heat sources – temperatures above 70-75 degrees F (21-24 degrees C) can cause the chocolate shell to soften or bloom. A cool pantry or cool countertop (away from direct sun and heat appliances) is the right storage environment.

Refrigerator: Not recommended for extended storage – temperature cycling between the refrigerator and room temperature can cause chocolate bloom (the dull, whitish surface coating that occurs when cocoa butter re-crystallizes at the surface during temperature changes). If refrigerated: bring to room temperature for 15-20 minutes before serving to allow the chocolate to temper back to room temperature before handling or gifting.

Gifting packaging: Place each heart in a mini cupcake liner inside a small box with tissue paper. A box of 6 hearts in a clear-windowed gift box with ribbon is the standard presentation. For shipping: place each heart in a mini cupcake liner, wedge them snugly so they can’t move (movement causes the chocolate shell to crack from impact), and place the box inside a padded mailer with bubble wrap on all sides. The chocolate shell is fragile when cold – pack at room temperature, not refrigerator cold.

Make-ahead: Make up to 2 weeks ahead and store at room temperature for gifting. The 2-week shelf life is an advantage over most confections – these are the Valentine’s Day candy to make the weekend before rather than the night before.

Chocolate Marshmallow Hearts Variations

Dark Chocolate And Sea Salt Hearts

Use 70% dark chocolate for the shell. After piping the sealing layer and before the final tap, place a single flake of Maldon or fleur de sel on top of the chocolate (visible on the finished bottom-turned-top when unmolded). The sea salt flake against the dark chocolate shell against the sweet marshmallow inside produces the most sophisticated version of these hearts – the adult version that feels genuinely gourmet. Skip the pink drizzle for this version; the sea salt is the decoration and the dark-and-white contrast of the single salt flake is the visual flourish.

White Chocolate Hearts With Colored Marshmallow

Use white chocolate or vanilla-flavored candy melts for the shells. Before placing the marshmallow, tint it gently with a tiny amount of pink food color gel applied with a clean fingertip – just a light touch of pink on the surface of the marshmallow. When the heart is bitten open, the white chocolate shell reveals a faintly pink marshmallow inside. The color-inside-the-color detail is a subtle version of the hidden element concept and is visually lovely in a delicate way. Top with a simple confectioners’ sugar dusting rather than a colored drizzle for a clean, elegant appearance.

Peppermint Marshmallow Hearts (Christmas Version)

Add 1/4 teaspoon of peppermint extract to the melted dark chocolate before piping (stir thoroughly to distribute). The peppermint-chocolate shell against the plain sweet marshmallow is a classic candy cane combination in heart form. Use red candy coloring (oil-based) in a white chocolate drizzle for a red-and-dark decoration that reads as Christmas rather than Valentine’s Day. Or use the same mold with a Christmas tree or star shape rather than a heart for a specifically holiday-shaped version.

Toasted Coconut Chocolate Hearts

After unmolding and before the decorative drizzle, press a small pinch of toasted shredded coconut onto the top surface of each heart. Drizzle white chocolate to hold the coconut in place. The coconut adds a visual texture contrast and a toasted-coconut flavor note that pairs particularly well with dark chocolate. For a more intense coconut presence: add 1/4 teaspoon of coconut extract to the melted chocolate before piping.

Peanut Butter Marshmallow Hearts

Replace the plain mini marshmallow with a mini marshmallow that has been coated in a thin layer of peanut butter – dip each marshmallow in smooth peanut butter, wipe off excess, and let the peanut butter set slightly before placing in the heart cavity. Use milk chocolate for the shell. The peanut butter-coated marshmallow produces a filling that tastes like a Reese’s cup crossed with a marshmallow – sweet, peanutty, soft. Top with a drizzle of remaining peanut butter thinned with a small amount of oil rather than colored white chocolate for a brown-on-brown effect that reads as deliberately styled.

Espresso And Cardamom Hearts

Add 1/2 teaspoon of instant espresso powder and 1/4 teaspoon of ground cardamom to the melted dark chocolate before piping – stir thoroughly until fully dissolved and incorporated. The espresso deepens the chocolate flavor; the cardamom adds a warm, slightly floral spice that is the most unexpected and interesting variation in this list. Use mini gourmet marshmallows if you can find them, or plain standard ones. Finish with a simple dusting of cocoa powder through a fine sieve rather than a colored drizzle. These are the hearts for the adults who don’t reach for standard sweet candy.

Vegan Chocolate Marshmallow Hearts

Use dairy-free chocolate (Enjoy Life, many Ghirardelli 70%+ products) and vegan marshmallows (Dandies brand produces vegan mini marshmallows that are available at most natural food stores and online). All other steps are identical. The finished hearts are indistinguishable from the standard version in appearance and very close in flavor – vegan marshmallows have a slightly different texture (firmer, less pillowy) than standard gelatin-based ones, but they work correctly in the chocolate shell and provide the expected textural contrast. For a vegan Valentine’s Day gift: these plus the Vegan Love Heart Cupcakes in the same box covers every dietary preference.

Serving Suggestions

The Gift Box Presentation

Six chocolate marshmallow hearts arranged in mini cupcake liner cups inside a small red or pink gift box is the classic presentation that makes these look like purchased confectionery. For a more substantial gift: combine 4 chocolate marshmallow hearts with 4 pieces of the Valentine’s Day Chocolate Bark and 4 pieces of the Chocolate-Covered Marshmallows in a larger box. The three confections together provide variety in both format (molded heart, bark shard, dipped marshmallow) and texture (crisp and filled, snapping thin bark, dipped-marshmallow) that makes the gift feel curated and abundant.

On A Valentine’s Day Dessert Board

  • Arrange the hearts in a row or cluster on a confectionery board alongside chocolate-covered pretzels, chocolate bark, truffles, and fresh strawberries
  • The heart shape stands upright when leaned against something – arrange them leaning against each other in groups of three for a dimensional presentation rather than laying flat
  • Add a small card identifying them (“Chocolate Marshmallow Hearts”) for anyone who hasn’t encountered them before and needs to know what they’re reaching for

Occasion Ideas

  • Valentine’s Day gift for teachers, neighbors, friends – six in a box with ribbon is a complete gift from a single afternoon’s work
  • Valentine’s Day class party treat – 30 pieces from one mold, individually wrapped in cellophane squares with a twist tie, is a complete class set with no cutting or portioning required
  • A homemade candy collection alongside other confections for the most impressive Valentine’s Day candy spread possible
  • Any occasion where a heart-shaped confection is appropriate: Mother’s Day (mother theme, switch to gold or pink drizzle), anniversary, birthday of someone who loves chocolate and marshmallows

Beverage Pairings

Hot coffee or espresso against the dark chocolate and sweet marshmallow center is the most satisfying adult pairing – the coffee bitterness amplifies the dark chocolate flavor and the sweet marshmallow provides a counterpoint. Champagne or sparkling rosé for a celebration – the bubbles cleanse the palate between bites and the slight acidity cuts through the richness of the chocolate shell. Hot cocoa for children alongside these hearts is meta in the best way: marshmallow-filled chocolate alongside hot cocoa is serving marshmallow-and-chocolate twice in the same experience, which is either too much or exactly enough depending on your position.

Chocolate Marshmallow Hearts Recipe

Chocolate Marshmallow Hearts FAQ

Do I Need A Special Silicone Mold Or Will Any Heart-Shaped Mold Work?

Silicone molds are specifically recommended because the flexibility of silicone is what produces a clean release from the set chocolate – you gently press the back of each cavity and the candy pops out without any sticking or damage. Rigid plastic or metal molds can work but require careful lining with a very thin layer of vegetable spray or by lightly rubbing the inside with a barely-damp paper towel before pouring chocolate – even then, release can be uneven and the finished surface may have marks from prying. Silicone is worth using for candy mold work. A 30-cavity mini heart silicone mold costs $8-12 and produces exactly the right size heart for this recipe. Available at craft stores, kitchen stores, and online.

Can I Use Large Marshmallows Instead Of Mini?

Large marshmallows cut into quarters or sixths work in standard cavity-size molds. The cut surface of the marshmallow should face down (toward the chocolate shell) so the smooth exterior of the marshmallow faces toward the sealing chocolate layer. Cut marshmallows release more moisture than intact marshmallows over time, which can make the chocolate shell slightly sticky at the interior surface after several days. Use mini marshmallows where possible; use cut large marshmallows within 3-4 days for best results.

My Chocolate Keeps Getting Thick While I’m Working. How Do I Keep It Fluid?

Chocolate cools and thickens as it sits at room temperature, especially in a cool kitchen. Two strategies: work faster (aim to complete the shell coating for all 30 cavities before the chocolate in the first cavities starts to thick significantly – about 10 minutes of efficient work); or keep the piping bag warm between uses by setting it in a cup or pitcher of warm water (not hot – you want to maintain temperature, not reheat to the point of the bag leaking). If the chocolate does thicken mid-session, microwave the bag in 5-second bursts at 50% power, massaging between each, until fluid again.

The Hearts Won’t Release From The Mold. What Do I Do?

Return the entire mold to the refrigerator for 5 more minutes, then try again with the gentle-flex technique. The most common reason a candy won’t release is that the chocolate hasn’t fully set at the center – the shell may feel solid at the surface but still be slightly soft in the thickest areas. Extended cold sets the chocolate more completely and improves release. If after additional refrigerator time the heart still resists: try the freezer for 3-5 minutes. Cold-firm chocolate releases from silicone most reliably. Never use a knife, skewer, or other tool to force the candy out – these damage the shell surface permanently.

Can I Make These Without Pink Drizzle?

Yes – the pink drizzle is entirely optional and the hearts are complete and beautiful without it. A simple dusting of powdered sugar through a fine sieve produces an elegant matte white coating that looks sophisticated without any colored decoration. Crushed freeze-dried raspberry scattered over the hearts while the sealing chocolate is still wet (before the final chill) provides color, flavor, and texture in one step without any additional melting. Edible gold luster dust brushed over the set hearts produces a dramatic, formal appearance. Or leave them plain – a smooth dark or milk chocolate heart is already beautiful without any additional decoration.

How Many Hearts Does One Batch Make?

The recipe as written, using a 30-cavity mini heart silicone mold, makes exactly 30 hearts. The 2 cups of chocolate is the right quantity to coat the shells and seal the tops for 30 mini heart cavities at a 1-2mm shell thickness. If your mold has a different cavity count: 1.5 cups of chocolate for 24 cavities; 1 cup for 15-16 cavities. For a doubled batch (60 hearts for a larger gifting occasion or class party): double all quantities and work in two mold batches since a 30-cavity mold can only produce 30 hearts at a time.

Recipes You May Like

If these chocolate marshmallow hearts have you in the spirit of Valentine’s Day confectionery that looks impressive and works beautifully in a gift box, here are three more from the blog in exactly the same category.

Valentine’s Day Chocolate Bark – The flat-pour chocolate confection that makes a natural companion to the molded hearts in a gift box. Where the hearts are individually shaped, filled, and three-dimensional, the bark is thin, flat, and broken into irregular pieces. Both are made by melting chocolate; both take under 30 minutes; both look beautiful. Together in one box or on one board, they provide visual and textural variety that makes the gift feel curated and substantial. The bark is the easiest-possible chocolate confection; the hearts are slightly more technical but produce a more elaborate result. Both belong in the Valentine’s repertoire.

Chocolate-Covered Marshmallows – The simpler marshmallow-in-chocolate format for when silicone heart molds aren’t available or when you want a quicker version of the same flavor concept. Where the hearts enclose the marshmallow completely in a shaped shell, the chocolate-covered marshmallows are simply whole marshmallows dipped in melted chocolate – the same flavors, a different presentation. Both are excellent; the molded hearts look more refined and gift-specific while the dipped marshmallows are faster and more casual.

Valentine’s Crack Candy – The saltine-cracker toffee confection that rounds out a Valentine’s Day confectionery spread with a completely different flavor register – sweet, salty, caramel, and chocolate all at once. Where the marshmallow hearts are sweet and soft, the crack candy is crispy, caramelized, and slightly addictive in a way that nothing sweet-only achieves. Include both in the same gift tin for a confectionery spread that covers both the sweet-sweet and the sweet-salty ends of the candy spectrum.

Conclusion

These chocolate marshmallow hearts are the Valentine’s Day confection that Emily turned into an annual February tradition by coming home from a market and describing heart-shaped chocolate with marshmallow inside at length, three different times, until I made them. Some recipe inspirations are elegant and spontaneous. Some are very specifically requested by a small person who really wants what they had at a market. Both produce recipes worth keeping.

The dark chocolate shell with sea salt is the adult version worth making for the people on your list who appreciate complexity. The milk chocolate with pink drizzle is the classic version Emily takes to her teacher every year. Making all three chocolate types in one session and mixing them in a gift box is the approach that produces the most impressive presentation for the same amount of total work.

Let Emily – or whoever is your Emily in this situation – manage the marshmallow centering. It takes longer than it needs to and produces better results and more investment than any other approach. Tell me in the comments which chocolate type you used first and whether the tapping-for-air-bubbles step was as important as I said it was. Save this to Pinterest for your next Valentine’s Day or special occasion candy-making session – and happy cooking!

Happy cooking! – Callie
