Homemade cookie cake recipe

There’s just something special about a giant, warm homemade cookie cake that brings everyone together—especially when it’s fresh from the oven and piled high with frosting. This is my go-to dessert for birthdays, lazy weekends, or anytime someone says, “I wish we had something sweet.” And yes, it always disappears fast.

If you’re into cookies that are soft and chewy with crispy edges, this one’s for you. It’s super easy (no mixer needed!), bakes in under 15 minutes, and pipes up beautifully with a simple buttercream. Oh—and the chopped chocolate chip trick? Game changer.

ingredients for homemade cookie cake

for the cookie cake:

• ½ cup unsalted butter (1 stick), melted
• ½ cup light brown sugar
• ¼ cup granulated sugar
• 1 large egg
• 1 ½ teaspoons vanilla extract
• ½ teaspoon baking soda
• ¼ teaspoon baking powder
• ¼ teaspoon salt
• 1 ½ cups all-purpose flour
• 1 cup semi-sweet chocolate chips (½ cup chopped, ½ cup whole)

for the frosting:

• ¼ cup unsalted butter, softened to room temperature
• 1 ¼ cups powdered sugar
• ¾ teaspoon vanilla extract
• pinch of salt
• 2 tablespoons milk

instructions to make homemade cookie cake

1. preheat the oven

Set oven to 350°F (175°C). Get your pan ready—grease it well or line with parchment paper.

2. chop the chocolate

Put ½ cup of chocolate chips in a plastic bag, then crush them gently with a rolling pin. This gives you a mix of flecks and chunks that melt into every bite. Set aside the other ½ cup of whole chips.

3. melt the butter

Microwave the stick of butter in a bowl for about 20–30 seconds. It should be just melted, not hot or bubbling.

4. mix the dough

• Add brown and white sugars to the melted butter and stir with a spatula.
• Stir in the egg and vanilla.
• Sprinkle in baking soda, baking powder, and salt; mix again.
• Add the flour last and mix until combined (dough will be soft and thick).

5. add the chocolate

Toss in the chopped and whole chocolate chips. Stir to combine. Don’t let the dough sit too long—it firms up fast.

6. press into pan

Spoon dough into your greased 11.5″ cookie cake pan (or a regular cake/pizza pan). Drop it in chunks so it’s easier to spread. Press gently into an even layer.

Pro tip: If you see 2–3 chips clumped together, separate them now—helps the cookie bake evenly and cut cleanly.

7. bake the cookie cake

Bake at 350°F for 12–14 minutes. It should look slightly underdone with golden edges—don’t overbake! I pull mine at 12 minutes.

Let it cool completely in the pan before trying to remove it. To remove: run a knife around the edge, flip onto a plate, then flip again onto your serving tray.

8. make the frosting

• Beat softened butter for 2 minutes until smooth.
• Slowly add powdered sugar while mixing on low. Scrape bowl as needed.
• Add vanilla and salt. Mix.
• Add milk 1 tbsp at a time until it’s smooth and pipeable.

If it’s too thick, add a tiny bit more milk. Too runny? Sprinkle in more powdered sugar.

9. decorate

Use a large star tip to pipe a border around the edges. Add sprinkles right away—the frosting sets quickly!

Want to add words like “Happy Birthday”? Double the frosting batch.

storage & reheating tips

• Room temperature: Keep covered with foil or in an airtight container for up to 3 days
• Refrigerator: Stays fresh up to a week (bring to room temp before serving)
• Freezer: You can freeze the undecorated cake for up to 2 months
• Reheat: Not needed! But you can warm slices for 5–10 seconds in the microwave if you love that melty chocolate feel

variations & tips for homemade cookie cake

• Swap chocolate chips with M&M’s or white chocolate chunks
• Add chopped nuts for crunch (pecans or walnuts are great)
• Use holiday-themed sprinkles for festive versions
• Don’t overmix the dough or the texture will be tough
• Grease your hands slightly with butter or oil to press dough more easily

Ever tried a peanut butter version? Just sub in half the butter with peanut butter—it’s insanely good.

faq about homemade cookie cake

how do i know when it’s done baking?

You want golden brown edges and a slightly underdone center—it will finish setting as it cools. Don’t wait for it to look fully baked in the oven.

can i double this recipe?

Yes! You can double it and use a 9×13” pan. The bake time may need an extra 2–3 minutes.

can i use store-bought frosting?

Totally. But homemade is smoother for piping and not as sweet. I love how this buttercream turns out.

what if i don’t have a cookie cake pan?

Use a round pizza pan or a springform pan instead. Just make sure it’s greased well or lined with parchment for easy removal.
