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 powdered sugar (for frosting)
  • 1/4 cup unsalted butter, softened (for frosting)
  • 1 teaspoon vanilla extract (for frosting)
  • 12 tablespoons milk (for frosting)

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 12-inch round pizza pan or a 10-inch springform pan.
  2. In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
  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.
  6. Fold in the chocolate chips by hand.
  7. Press the cookie dough evenly into your prepared pan. This recipe makes a thick cookie cake.
  8. Bake for 20 to 25 minutes, or until the edges are golden brown and the center is set but still slightly soft for a chewy texture.
  9. Let the cookie cake cool completely in the pan on a wire rack before frosting.
  10. To make the frosting, beat the softened butter until smooth. Gradually add the powdered sugar, vanilla extract, and milk, one tablespoon at a time, until you reach a smooth, spreadable consistency.
  11. Spread the homemade cookie cake frosting evenly over the cooled cookie cake. Decorate with extra chocolate chips or sprinkles for a birthday cookie cake idea.

Notes

  • For a thicker cookie cake, use a 9-inch round pan instead of a 12-inch pan, and increase the baking time by 5-8 minutes.
  • If you want a copycat cookie cake recipe texture, slightly underbake it; it will firm up as it cools.
  • This recipe is excellent for making a sheet pan cookie cake large batch; press the dough into a rimmed half sheet pan and bake for 25-30 minutes.
