Ingredients

Scale
  • 1 cup unsalted butter, softened
  • 1 cup packed light brown sugar
  • 1/2 cup granulated sugar
  • 2 large eggs
  • 1 tablespoon vanilla extract
  • 2 1/4 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 1/2 cups semi-sweet chocolate chips
  • 1 cup milk chocolate chips (optional, for extra gooeyness)
  • 1 cup buttercream frosting (for decorating)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour a 12-inch round cake pan or line a half sheet pan with parchment paper.
  2. In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture is light and fluffy. This step builds texture.
  3. Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  4. In a separate medium bowl, whisk together the flour, baking soda, and salt.
  5. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Do not overmix the dough.
  6. Fold in the semi-sweet and milk chocolate chips using a spatula.
  7. Press the cookie dough evenly into your prepared pan. For a thick cake, use a round pan; for a crowd, use a sheet pan.
  8. Bake for 20 to 25 minutes for a round pan, or 25 to 30 minutes for a sheet pan, or until the edges are golden brown but the center still looks slightly soft. This ensures a chewy texture.
  9. Let the cookie cake cool completely in the pan on a wire rack before frosting. Cooling is essential for structure.
  10. Once cool, spread your homemade buttercream frosting over the top. Decorate with sprinkles or extra chocolate chips for a festive birthday cookie cake look.

Notes

  • For a copycat bakery cookie cake texture, slightly underbake the center. It will set as it cools.
  • If you prefer a thicker cookie cake, use a 10-inch round pan instead of a 12-inch pan.
  • Chill the dough for 30 minutes before pressing it into the pan for richer flavor development.
  • Use high-quality butter for the best flavor in this large format cookie baking.
