Inspired by the Sprinkles Cookie Cupcake, I've created my new Chocolate Chip Cookie Cake with layers of dark chocolate cookie crust, tender yellow chocolate chip cake, silky brown sugar frosting and dusted in chocolate chip cookie crumbs.

Instructions

For the Chocolate Cookie Crust

  1. Preheat your oven to 300 degrees F. Spray three 8-inch or four 6-inch round cake pans with nonstick spray, line the bottoms with parchment paper and spray again. Set aside.
  2. Combine the flour, cornstarch, sugar, cocoa powder, and salt in the bowl of a stand mixer fitted with the paddle attachment and paddle on low speed until mixed.
  3. Add the butter and paddle on low speed until the mixture starts to come together in small clusters.
  4. Spread 8 ounces of the chocolate crumbs on the parchment in each the three 8-inch cake pans or 6 ounces in each of the 6-inch pans. Using the back of a spoon, push the crumbs together to form a crust. Bake for 15 minutes.
  5. Let the crust cool a bit while you make the yellow cake. 

For the Yellow Chocolate Chip Cake

  1. While the chocolate cookie crust is cooling, turn your oven to 350 degrees F.
  2. In the bowl of a stand mixer fitted with a paddle attachment, combine the butter, oil, sugar and salt. Beat on medium speed for about 2 minutes, until light and fluffy.
  3. Turn the mixer to medium-low and add the eggs and egg yolks, one at a time, scraping down the sides of the bowl in between each addition.
  4. With the mixer on low, alternately add the flour and baking powder with the sour cream, starting and ending with the flour. Mix until combined.
  5. Add the butter and vanilla extract. Mix on low until combined.
  6. In a small bowl, combine the mini chocolate chips with 1 tablespoon of flour. This helps to coat the chocolate chips so they don't sink to the bottom of the cake.
  7. Fold the chocolate chips into the cake batter.
  8. Evenly distribute the cake batter in the pans with the chocolate cookie crust.
  9. Bake the cakes and cookie crust for 25 to 30 minutes, until a toothpick inserted in the center of the cakes comes out with only just a few crumbs on it.
  10. Cool the cakes on wire racks for about 10 minutes. Carefully invert the cakes onto cooking racks to cool completely. If you don't plan to stack and decorate the cake right away, wrap each layer in plastic wrap or tin foil and freeze. 

For the Brown Sugar Frosting

  1. In a medium sauce pan, combine the brown sugar and water over medium heat. Stir to combine. Bring the mixture to a soft boil and let cook for about 5 minutes to thicken. Remove from heat and let cool for about 10 minutes. It won't be hot but it won't be room temperature.
  2. When the brown sugar syrup has cooled a little, put the butter in the bowl of a stand mixer fitted with the paddle attachment. Beat the butter for about 2 minutes, until light and fluffy.
  3. With the mixer on low speed, gradually add the powdered sugar.
  4. Once all the powdered sugar is incorporated, slowly stream the brown sugar syrup into the bowl. Once the syrup has been added, turn the mixer up to medium-high and beat for about 5 minutes. Don't worry if the buttercream is soft. 
  5. If the mixer gets too soft, refrigerate the frosting for 30 to 60 minutes. Beat the frosting again for a couple minutes. 

Assembly

  1. Spread a small dollop of frosting on your cake board. Place the first cake layer on the board, with the chocolate cookie crust on the bottom.
  2. Spread about 3/4 cup of the brown sugar frosting on top of the cake layer. Make sure to get eye level with the cake to ensure it is level.
  3. Sprinkle three crushed chocolate chip cookies (big chunks of cookie are ok!) on the frosting and tap them with your fingers to gently set them into the frosting.
  4. Place the second cake layer, chocolate cookie crust on the bottom, on top of the frosting and cookie crumbs. Repeat step 2 and 3.
  5. Place the final cake layer, chocolate cookie crust on the bottom, on top of the second layer of frosting and cookie crumbs.
  6. Spread a thin layer of frosting around the entire cake to lock in any crumbs. This is called the crumb coat. Freeze the cake for 10 minutes to ensure the crumbs get locked into this coat of frosting. After the frosting is set, continue to frost the cake. I used about 16 cookies to pulse in my blender to get find crumbs for the outside of my cake.
