Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, softened
  • ¾ cup packed light brown sugar
  • ¾ cup granulated sugar
  • 2 large eggs
  • 1 tablespoon vanilla extract
  • 2 ¼ cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 ½ cups semi-sweet chocolate chips (use a mix of chopped and whole chips)
  • 1 cup vanilla buttercream frosting
  • Optional: Sprinkles for decoration

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease a 12-inch round pizza pan or a 10-inch springform pan. If using a springform pan, line the bottom 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 chocolate chips using a spatula.
  7. Press the dough evenly into your prepared pan. For a bakery style look, press some extra chocolate chips onto the top surface.
  8. Bake for 22 to 28 minutes. The edges should look set and golden brown, but the center should still look slightly soft and underbaked. This ensures a soft and chewy center.
  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 the vanilla buttercream frosting evenly over the top of the cookie cake. Decorate with sprinkles if desired.
  11. Slice and serve this giant chocolate chip cookie for your next celebration dessert.

Notes

  • For the chewiest texture, slightly underbake the cake. The residual heat will finish cooking it as it cools.
  • Use room temperature eggs for better incorporation into the batter.
  • If you want a thicker cake, use a 9-inch round pan instead of a 12-inch pan, but increase the baking time by 5-10 minutes.
