I made this cake for my sister in law's birthday. I've tried this recipe before, but it didn't really turn out as I had hoped due to the cheap disposable pan I was using. The flavor was definitely there though, so I tucked the recipe away... determined that I would eventually give it another shot. This time I made the commitment and bought a solid pizza pan (no more disposable!). I've wanted to try making homemade pizza anyway, so I figured the purchase was a valid one. My pan worked like a charm. This cookie cake was awesome! Now, I just have to commit to the pizza making. :)
1 cup (2 sticks) unsalted butter, softened
1 cup packed light brown sugar
1/2 cup granulated sugar
2 large eggs
2 cups plus 2 tbsp all-purpose flour
1 tsp baking soda
1/2 tsp salt
1 1/2 tsp pure vanilla extract
1 1/2 cups bittersweet chocolate chips
3/4 cup white chocolate chips
1 container each of chocolate and vanilla frosting
Preheat oven to 375°F. Line a 14-inch, round pizza pan with parchment paper. Grease the parchment paper with cooking spray; set aside.
In a large bowl, cream butter and sugars. Add eggs, one at a time, beating well after each addition.
In a medium bowl, whisk together flour, baking soda, and salt. Add to butter mixture, mixing until incorporated, then add vanilla extract and finish mixing. Fold in dark and white chocolate chips. Spread across the bottom of the prepared pan.
Bake until edges are golden and the cookie is set but the center is slightly soft, about 20-25 minutes. Cool on wire rack.
Decorate with frosting. Cut into wedges to serve.
