Tips & Variations
- For extra chewy texture, chill the dough for 30 minutes before baking.
- Try swapping chocolate chips for white chocolate or butterscotch chips for a different flavor.
- If you prefer a thinner frosting, add milk one teaspoon at a time until you reach the right consistency.
- You can bake the dough as cookies instead of a cake if desired—just adjust the baking time accordingly.
Storage
Store the cookie cake in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days. Reheat slices briefly in the microwave if you prefer a warm treat. The cake can also be frozen uncut for up to one month; thaw before frosting.

FAQs
Can I use salted butter instead of unsalted?
Yes, but reduce or omit the added salt in the recipe to avoid an overly salty flavor.
How do I know when the cookie cake is done baking?
The edges should be lightly golden and the center just barely set. The cookie might still be soft but will firm up as it cools.

Perfect for celebrations or a fun twist on traditional desserts, this cookie cake is chewy, chocolaty, and beautifully decorated for any occasion.
Ingredients
Cookie Cake:
- 3/4 cup unsalted butter, softened
- 3/4 cup light brown sugar
- 1/4 cup granulated sugar
- 1 large egg
- 2 teaspoons vanilla extract
- 2 cups all-purpose flour
- 2 teaspoons cornstarch
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 1/2 cups chocolate chips
Chocolate Frosting:
- 1/4 cup unsalted butter, softened
- 2 cups powdered sugar
- 2 tablespoons cocoa powder
- 1/8 teaspoon salt
- 1/2 teaspoon vanilla extract
- 1–2 tablespoons milk
Instructions
- Make Cake: Preheat your oven to 350º F (175º C). Grease two 9-inch cake pans, a springform pan, or use one large pizza pan.
- Cream Butter and Sugars: In a stand mixer, cream together the softened unsalted butter, light brown sugar, and granulated sugar until the mixture is light and fluffy, approximately 2 minutes.
- Add Egg and Vanilla: Beat in the egg and vanilla extract until fully incorporated and the batter is smooth.
- Mix Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, cornstarch, baking soda, and salt. Gradually add these dry ingredients to the wet mixture, mixing just until combined to avoid overworking the dough.
- Fold in Chocolate Chips: Gently fold in the chocolate chips until they are evenly distributed throughout the dough.
- Shape and Bake: Press the cookie dough evenly into your prepared pans—the dough can be divided into two cake pans, or spread out in a larger pizza pan. Bake smaller pans for 13-15 minutes or the larger pan for about 18 minutes, until edges are lightly golden and the center is just set. Oven variations may affect baking times, so watch closely.
- Cool: Remove the cookie cake from the oven and allow it to cool completely in the pan on a wire rack.
- Prepare Frosting: Using a hand mixer or whisk attachment of a stand mixer, beat the softened butter until creamy and smooth. Gradually add powdered sugar, cocoa powder, and salt, mixing well after each addition.
- Add Vanilla and Milk: Stir in vanilla extract. Slowly add milk one tablespoon at a time, beating until the frosting reaches a smooth and spreadable consistency. Adjust the milk or powdered sugar quantities as needed for desired thickness.
- Frost and Decorate: Once the cookie cake is completely cooled, spread or pipe the chocolate frosting evenly over the top. Decorate with sprinkles, colored frosting, or your choice of toppings to personalize your celebration dessert.
Notes
- For a chewier center, do not overbake the cookie cake; remove it when edges are set but center slightly soft.
- You can freeze leftover cookie dough for up to one month; thaw before baking.
- If you prefer, the frosting can be made less sweet by reducing powdered sugar slightly or adding a pinch of salt.
- Use room temperature ingredients for easier mixing and better consistency.
- Substitute dairy-free butter and milk to make the frosting vegan-friendly, though the cookie might still contain egg unless substituted.
