Ingredients

Scale
  • 2 ½ cups (315g) all-purpose flour, sifted
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup (227g) unsalted butter, softened
  • 1 cup (200g) brown sugar, packed
  • ½ cup (100g) granulated sugar
  • 2 large eggs, at room temperature
  • 2 teaspoons pure vanilla extract
  • 1 ½ cups (270g) semi-sweet chocolate chips
  • ½ cup (113g) unsalted butter, softened (for buttercream)
  • 3 cups (360g) powdered sugar, sifted
  • 2–3 tablespoons (30–45ml) heavy cream
  • 1 teaspoon pure vanilla extract (for buttercream)
  • Pinch of salt (for buttercream)

Instructions

  1. Preheat oven to 350°F (175°C). Lightly grease a 9-inch round cake pan and line the bottom with parchment paper.
  2. In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Set aside.
  3. In a large bowl, beat softened butter, brown sugar, and granulated sugar with an electric mixer on medium speed until fluffy and pale, about 3-4 minutes.
  4. Beat in eggs one at a time, fully incorporating each before adding the next. Mix in vanilla extract.
  5. Slowly add dry ingredients to the wet mixture and mix on low speed until just combined. Avoid overmixing.
  6. Fold in chocolate chips gently with a spatula.
  7. Spread batter evenly into prepared pan, smoothing the top.
  8. Bake for 25-30 minutes. Check at 25 minutes with a toothpick; it should come out with a few moist crumbs.
  9. Cool in pan for 15 minutes, then transfer to a cooling rack to cool completely before frosting.
  10. For the buttercream, beat softened butter until creamy. Gradually add powdered sugar, alternating with heavy cream, until smooth and spreadable.
  11. Mix in vanilla extract and a pinch of salt. Adjust consistency with more cream or sugar if needed.
  12. Once cake is cool, spread buttercream evenly over the top. Optionally pipe decorative swirls or add sprinkles.
  13. Slice into wedges and serve.

Notes

Do not overmix the batter after adding flour to keep the cookie cake soft. Use room temperature eggs and butter for proper creaming. Check the cake at 25 minutes with a toothpick to avoid overbaking. Cool completely before frosting to prevent buttercream meltdown. Cover edges with foil if browning too fast. Buttercream can be chilled for 10 minutes before spreading for easier handling.
