Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, softened
  • 3/4 cup granulated sugar
  • 3/4 cup packed light brown 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 vanilla buttercream frosting ingredients (listed separately below)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour a 12-inch round pizza pan or a 9-inch springform pan.
  2. In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
  3. Beat in the eggs one at a time, then mix 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 using a spatula.
  7. Press the cookie dough evenly into the prepared pan.
  8. Bake for 20 to 25 minutes, or until the edges are golden brown and the center is set but still slightly soft.
  9. Let the cookie cake cool completely in the pan on a wire rack before frosting.
  10. Prepare the frosting: Beat 1/2 cup softened butter, 3 cups powdered sugar, 1 teaspoon vanilla extract, and 2-3 tablespoons milk until smooth and creamy. Add more milk if needed for spreading consistency.
  11. Spread the vanilla buttercream evenly over the cooled cookie cake. Decorate with extra chocolate chips if desired.

Notes

  • For a chewier center, slightly underbake the cake by about 2 minutes.
  • If using a springform pan, line the bottom with parchment paper before greasing for easy removal.
  • Chill the dough for 30 minutes before pressing it into the pan for thicker cookies.
