Ingredients

For the cake

  • 2 cups (260 g) all purpose flour
  • 1 teaspoon salt
  • ½ teaspoon baking powder
  • ¾ cup (169 g) unsalted butter, at room temperature
  • ¾ cup (150 g) light brown sugar, packed
  • ½ cup (100 g) granulated sugar
  • 1 large egg, at room temperature
  • 1 large egg yolk, at room temperature
  • 2 teaspoons vanilla extract
  • 1 ½ cups (255 g) semisweet chocolate chips

For the frosting

  • ½ cup (113 g) unsalted butter, at room temperature
  • 1 ½ cups (180 g) confectioners' sugar
  • ¼ cup (21 g) unsweetened cocoa powder
  • 2 tablespoons heavy cream
  • Rainbow sprinkles for decorating

Instructions

Make the cake

  • Preheat the oven to 350℉. Grease a 9-inch springform pan and line the bottom with parchment paper.
  • In a medium bowl, whisk the flour, salt, and baking powder together.
  • In a large mixing bowl, beat the butter and both sugars together until smooth, about 1 minute.
  • Mix in the egg, egg yolk, and vanilla until combined.
  • Add the flour mixture and mix just until combined.
  • Stir in the chocolate chips.
  • Spread the dough into the prepared pan and bake for 22-25 minutes, until edges are lightly golden and center is puffed.
  • Cool completely before removing the sides of the pan, about 2 hours or refrigerate for 1 hour.

Make the frosting

  • In a large mixing bowl, beat the butter until smooth, about 2 minutes.
  • Add the powdered sugar and cocoa powder and mix on low speed until fully combined.
  • Add the heavy cream and mix on medium speed until frosting is light and fluffy.
  • Transfer frosting to a piping bag fitted with desired piping tip and pipe a border of frosting around the outer edges of cake. Decorate with sprinkles.

Notes

  • Your cookie cake is ready when it's perfectly puffed and has those lovely light golden edges! If you’re on the fence about doneness, don’t hesitate to take it out. A little underbaked? No problem! It just means a delightfully soft center. Enjoy that gooey goodness!
