Ingredients

Scale
  • 1 cup (227g) unsalted butter, softened
  • 1 cup (200g) light brown sugar, packed
  • 1/2 cup (100g) granulated sugar
  • 2 large eggs, room temperature
  • 2 teaspoons pure vanilla extract
  • 2 1/2 cups (315g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 2 cups (340g) semi-sweet chocolate chips
  • 1/2 cup (113g) unsalted butter, softened (for buttercream)
  • 2 cups (240g) powdered sugar, sifted
  • 2 tablespoons heavy cream or milk
  • 1 teaspoon vanilla extract (for buttercream)
  • Pinch of salt (for buttercream)

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease your 9-inch cake pan or line it with parchment paper.
  2. In a large bowl, beat together 1 cup softened butter, brown sugar, and granulated sugar on medium speed for 3-4 minutes until light and fluffy.
  3. Beat in the eggs one at a time, then stir in vanilla extract. Mix thoroughly but avoid overmixing.
  4. In a separate bowl, whisk together flour, baking soda, and salt. Gradually add this to the wet mixture in batches, mixing on low speed just until combined.
  5. Using a rubber spatula, gently fold in the 2 cups of chocolate chips until evenly distributed.
  6. Scrape the batter into the prepared pan and spread evenly with a spatula.
  7. Bake for 25-30 minutes until edges are golden brown and center is just set but still soft to the touch.
  8. Let the cookie cake cool in the pan for at least 20 minutes, then transfer to a wire rack to cool completely.
  9. For the buttercream border, beat 1/2 cup softened butter until smooth (about 2 minutes). Gradually add powdered sugar, alternating with cream and vanilla, until fluffy and pipeable. Add a pinch of salt if desired.
  10. Fill a piping bag and pipe a decorative border around the cooled cookie cake.
  11. Slice carefully with a sharp knife warmed under hot water for clean cuts and serve.

Notes

If buttercream is too soft, chill for 10 minutes before piping. Cooling the cookie cake completely is essential for the buttercream to set properly. Use softened butter that is cool to the touch for best creaming results. Avoid overmixing flour to prevent toughness. Use good quality chocolate chips for best melting and flavor.
