Ingredients & Substitutions
For the Crust and Topping:

- 1 ¼ cups all-purpose flour – Can be substituted with whole wheat flour or a gluten-free blend.
- ½ cup brown sugar – Adds a deep, caramel-like sweetness. Coconut sugar works too.
- ¼ teaspoon salt – Enhances the flavors.
- ½ teaspoon cinnamon – Complements the sweetness of the peaches.
- ½ cup unsalted butter, melted – Can be replaced with coconut oil for a dairy-free option.
- 2 tablespoons honey or maple syrup – Natural sweeteners that add a hint of extra flavor.
For the Peach Filling:
- 3-4 medium fresh peaches (peeled, pitted, and diced; about 2 cups) – Can substitute frozen or canned peaches (drained).
- ¼ cup granulated sugar – Adjust based on the sweetness of your peaches.
- 2 tablespoons cornstarch – Helps thicken the filling.
- 1 tablespoon lemon juice – Brightens up the flavor and balances sweetness.
- ½ teaspoon vanilla extract – Adds warmth and depth.
Step-by-Step Instructions
Preheat the Oven
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper, leaving some overhang for easy removal.
Make the Crust and Topping
In a medium bowl, mix together the oats, flour, brown sugar, salt, and cinnamon.
Add the melted butter and honey (or maple syrup) to the dry ingredients and mix until crumbly.
Reserve about ¾ cup of the mixture for the topping and press the remaining mixture evenly into the prepared baking dish to form the crust.
Prepare the Peach Filling
In a saucepan over medium heat, combine the diced peaches, sugar, cornstarch, lemon juice, and vanilla extract.
Cook, stirring occasionally, for 5-7 minutes, until the mixture thickens and becomes jam-like. Remove from heat and let it cool slightly.
Assemble the Bars
Spread the peach filling evenly over the crust.
Sprinkle the reserved crumble mixture over the top of the peach layer.
Bake
Bake in the preheated oven for 25-30 minutes, or until the topping is golden brown and the filling is bubbling slightly.
Cool and Slice
Allow the bars to cool completely in the pan (about 1 hour). For easier slicing, refrigerate for 20-30 minutes before cutting into squares or rectangles.

Serve and Enjoy
Serve as a quick breakfast, snack, or even dessert. These bars are delicious on their own or with a dollop of yogurt on top.
Expert Tips & Tricks
Best Practices
For extra crunch, add chopped nuts like pecans or almonds to the crumble topping.
Use ripe peaches for the best natural sweetness. If your peaches aren’t sweet enough, add an extra tablespoon of sugar.
Common Mistakes
Don’t skip the cornstarch, or your filling might turn out too runny.
Make sure the bars are fully cooled before cutting to avoid a crumbly mess.
Time-Saving Tips
Make the peach filling a day in advance and store it in the fridge.
Freeze leftover bars for a grab-and-go snack anytime.
Serving Suggestions
Pairings
These bars go perfectly with a warm cup of tea or coffee.
For a full breakfast spread, serve alongside a French Omelette with Fines Herbes.
Presentation Ideas
Dust the bars with powdered sugar for a bakery-style look.
Drizzle with a simple glaze made from powdered sugar and milk for extra sweetness.
Beverage Pairings
Enjoy with a vanilla latte or a fresh fruit smoothie.
Pair with a chilled glass of almond milk for a dairy-free treat.
Storage & Reheating
Leftover Storage
Store bars in an airtight container at room temperature for up to 3 days.
For longer storage, refrigerate for up to a week or freeze for up to 3 months.
Reheating Methods
Enjoy cold or at room temperature, or warm them in the microwave for 10-15 seconds for a fresh-from-the-oven taste.
