Rich, buttery chocolate chip cookie baked as a cake-sized dessert. This recipe yields a decadent chocolate chip cookie cake with a soft, chewy center and a slightly crisp edge. Finish it with a smooth buttercream frosting for a homemade treat that easily rivals store-bought cookie cakes.

I baked this as a Valentine’s Day cookie cake as a practice run for my husband’s birthday. He’s had cookie cakes every birthday since he was a child, and after seeing how expensive they can be, I wanted to learn to make one at home. My sister-in-law made one for his birthday last year and it was better than anything we bought in a store, so she generously shared her recipe with me.

I kept the cake simple and classic. It was fun to press the dough into a large pan and watch a familiar cookie texture take on a new, cake-like form. We couldn’t help sneaking bites while it cooled—cookie cakes have a way of disappearing fast!

Chocolate Chip Cookie Cake Recipe

This chocolate chip cookie cake is simple to make and easy to customize. The method uses familiar cookie ingredients, but the batter is pressed into a large round pan and baked like a cake. The result is a dessert with the comforting flavor of fresh-baked cookies and a shareable, celebratory size perfect for birthdays, holidays, or any occasion.

Equipment

Mixer (stand or hand mixer)
Mixing bowl
12-inch round pan (or another pan with sides)
Spatula
Parchment paper
Large cookie sheet or flat board for flipping
Cake plate or cardboard covered with foil for presenting or storing

Ingredients

1 cup butter, softened and slightly melted
1 cup white sugar
1/2 cup packed light brown sugar
1/2 cup packed dark brown sugar
2 eggs
2 tsp vanilla extract
1 tsp baking soda
2 tsp hot water
1/2 tsp salt
2 3/4 cups all-purpose flour
1 3/4 cups milk chocolate chips

Instructions

Preheat the oven to 350°F (175°C).
Lightly grease a 12-inch round cookie pan and line the bottom with parchment paper.
In a mixer, cream together the butter, white sugar, and both brown sugars until smooth and well combined.
Beat in the eggs one at a time, then stir in the vanilla extract.
Dissolve the baking soda in the hot water, then add it to the batter and mix in the salt.
Gradually mix in the flour until incorporated, then fold in the chocolate chips.
Transfer the dough to the prepared pan. Press it down evenly so it’s about 1/2 inch (1.3 cm) high. For a smooth, even surface, place a piece of parchment over the dough and gently press it flat; remove the top parchment before baking.
Bake for 20–22 minutes, until the top is golden brown. The center should still be slightly soft to keep that chewy texture.
Allow the cookie cake to cool in the pan for about 15 minutes.
Place a large cookie sheet or flat board over the pan and carefully flip the pan so the cookie cake transfers onto the sheet. Peel off the parchment from the bottom.
Flip the cookie cake again onto your serving plate or cake stand, then decorate with buttercream icing or any frosting of your choice.

Topping and Serving Suggestions

A classic sweet buttercream frosting complements the warm, chocolate-studded cookie base. You can pipe messages or decorations for birthdays and special occasions, or keep it simple with swirls of frosting and extra chocolate chips on top. For a fun twist, try a cream-cheese frosting, a drizzle of caramel, or a sprinkle of sea salt for contrast.

Tips for Best Results

Soften the butter but avoid melting it completely; slightly melted butter still yields a tender texture.
Do not overbake—remove the cookie cake when the edges are set and the center is slightly soft. It will continue to set as it cools.
Press the dough evenly to ensure uniform baking; using a sheet of parchment on top helps create a smooth surface.
To achieve a chewier center, underbake by a minute or two and let it rest before slicing.
Experiment with mix-ins like dark chocolate chips, white chocolate, chopped nuts, or a handful of toffee bits.

Storage

Store the cookie cake in an airtight container or cover it with plastic wrap. It keeps well at room temperature for 2–3 days. For longer storage, refrigerate for up to a week or freeze individual slices wrapped tightly; thaw at room temperature before serving.

My sister-in-law also shared a favorite buttercream recipe that pairs beautifully with this cookie cake. The combination of a soft cookie interior, crispy edges, and creamy frosting makes every bite irresistible.

Enjoy this cookie cake for birthdays, holidays, or any time you want a crowd-pleasing dessert that feels homemade and special. Do you love cookie cakes as much as we do? What are your favorite ways to celebrate Valentine’s Day—do you dine out, cook something special, or bake your own sweet treats?
