Servings 8


  • 3x9 inch baking pans
  • Stand mixer
  • Medium mixing bowl


Cookie Cake

  • 3 cups All purpose flour
  • 2 tsp corn starch
  • 1 cup unsalted butter
  • 1 cup brown sugar
  • 1/2 cup granulated sugar
  • 2 eggs
  • 2 tsp vanilla extract
  • 2 cups chocolate chips

Peanut Butter Frosting

  • 1 cup unsalted butter
  • 1/2 cup creamy peanut butter
  • 1 cup confectioners’ sugar
  • 1 tsp pure vanilla extract


Cookie Cake:

  • Preheat oven to 350°F. Grease 3X9-inch cake pans, line with parchment paper and grease the parchment paper. (If there is anything I've learned in baking is always grease the parchment paper).
  • Whisk the flour, cornstarch, baking soda, and salt together in a mixing bowl.
  • Use a stand mixer fitted with a paddle attachment and beat the butter, brown sugar, and granulated sugar together on a medium-high speed until smooth. This took about 5 minutes. Add the eggs individually followed by the vanilla extract. Make sure it's evenly distributed.
  • Slowly add bowl of dry ingredients to the bowl of wet ingredients. Mix on a low setting until evenly combined. Then add the chocolate chips. The dough will be VERY thick and sticky.
  • Divide cookie dough between the pans and press down to make flat and even.

  • Bake for 20 minutes or until the cake layers are lightly brown on top and a toothpick inserted in the center comes out mostly clean. You'll probably get melted chocolate chip on there and that's fine.
  • Let completely cool.

  • Beat the butter and peanut butter together on medium speed until creamy and smooth. Then add the sugar, vanilla extract, and 1 Tablespoon milk. After completely mixing, add the second tablespoon of milk. You can add more milk if you find the frosting too thick.


  • Place 1 cake layer on stand. Evenly cover the top with frosting. Add each layer with a layer of frosting. Then add frosting to the sides.
  • Stored covered in your refrigerator
