Equipment

  • one 9" round baking pan

Ingredients

Cookie Cake

  • cup all purpose flour
  • ¾ teaspoon baking soda
  • ½ teaspoon salt
  • ½ cup unsalted butter room temperature
  • 1 cup light brown sugar
  • 1 large egg room temperature
  • 2 teaspoons vanilla extract
  • cups semi-sweet chocolate chips

Chocolate Frosting

  • ½ cup unsalted butter room temperature
  • cups powdered sugar
  • ¼ cup cocoa powder
  • ½ teaspoon vanilla extract
  • teaspoon salt
  • 4-6 tablespoons heavy whipping cream
  • sprinkles

Instructions

Cookie Cake

  • Preheat oven to 350°F (180°C). Line a 9" round baking pan with parchment and grease the sides. Set aside.
  • Whisk flour, baking soda, and salt together in a medium sized bowl. Set aside.
  • Add butter and sugar to a large bowl and beat until well creamed together, about 3 minutes. Add egg and vanilla and mix to combine.
  • Add in dry ingredients and chocolate chips. Mix until just combined. The batter will be thick.
  • Transfer batter into the prepared baking pan. Use your hand to press the cookie dough evenly into the baking pan. Bake for 20-25 minutes, or until the edges of the cookie cake are golden.
  • Remove from oven and let cake cool in it's pan for 20 minutes. Run a knife around the outside edge of the cookie cake, then flip out and let cool on a wire rack.

Chocolate Frosting

  • Add butter and powdered sugar to a large bowl. Beat until well combined, about 3 minutes.
  • Add cocoa powder, vanilla, and salt, and mix to combine. Add heavy whipping cream, 1 tablespoon at a time, until you get a piping consistency.
  • Pipe frosting on top of cooled cookie cake. Add sprinkles on top.
  • Store cookie cake at room temperature for up to 3 days.

Notes

  • You can substitute salted butter for unsalted butter in this recipe. Replace the salt in the cake for ¼ teaspoon instead. Omit the extra salt in the frosting.
  • Don't overbake the cookie cake. You want it slightly gooey in the center, but still stable. Remove the cake when it is lightly golden on top.
  • Instead of straight chocolate frosting, alternate between chocolate and vanilla piped frosting. Or just use vanilla frosting.
