This chocolate chip cookie cake recipe is very easy and super delicious! The cookie dough is pressed into a pan and baked into the best cookie cake for anyone's birthday. This recipe includes a simple buttercream frosting recipe so you can easily decorate the homemade cake.
Preheat oven to 350°F. Spray 9- or 10-inch cake pan or springform pan with Baker's Joy or line bottom with parchment paper; set aside.
In a large mixing bowl, cream together the butter and sugars until light and fluffy; about 1 minute. Stir in the vanilla, then the egg and yolk. Beat on medium high for 3 minutes.
In a separate mixing bowl, whisk together the flour, cornstarch, baking soda and salt. Add to the wet ingredients and mix until just incorporated. Stir in the chocolate chips.
Press the cookie batter into the prepared pan. Bake for 20 to 25 minutes until golden. Remove from oven and set pan on wire rack to cool completely. Once cooled, remove from pan and decorate with optional frosting recipe, or as desired.
For the frosting:
Beat butter and 3 cups of powdered sugar on low speed until combined. Mix in vanilla and 1 tablespoon of milk. Continue to beat on medium high speed, adding 1 tablespoon of milk at a time with additional powdered sugar until reaches desired consistency and taste. I prefer a sweet and stiff frosting to hold star shape while decorating cake, which takes about 5 minutes of beating.
To quickly bring butter to room temperature, cut into small pieces.
To quickly bring eggs to room temperature, let set in a bowl of hot water for 5 minutes.
My favorite nonstick spray is Baker's Joy.
