  • ¾ cup butter softened
  • ¾ cup brown sugar tightly packed
  • cup sugar
  • 1 egg + 1 egg yolk
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 1 ½ teaspoon cornstarch
  • ½ teaspoon baking powder
  • ¾ teaspoon salt
  • 1 cup chocolate chips
  • 2 Tablespoons sprinkles

Chocolate Frosting

  • 1/2 cup 1 stick salted butter, softened to room temperature
  • 1 1/2 cups powdered sugar
  • 1/4 cup cocoa powder
  • 1/2 teaspoon vanilla extract
  • 1-2 teaspoons milk


  • Preheat oven to 350F (177C) and prepare a 10" round pan by lining the bottom with parchment paper or by lightly greasing. Set aside.
  • Combine softened butter and sugars in a large bowl and use an electric mixer to beat well until light and fluffy. Add eggs, and egg yolk one at a time, stirring well after each addition. Stir in vanilla extract.
  • Add in flour, cornstarch, baking powder, and salt and mix in until combined. Stir in chocolate chips and sprinkles.
  • Spread batter evenly into prepared pan. Bake on 350F for 30 minutes or until edges just begin to turn golden brown.
  • Prepare chocolate frosting while the cookie cake cools. In electric mixer cream butter and sugars together until light and fluffy. Mix in cocoa powder and vanilla extract. Pause to scrape down the sides of the bowl with a spatula. If the frosting is thick, add milk (start with just 1 teaspoon, if consistency is still too stiff add another) and beat well.
  • Transfer frosting to a piping bag and pipe icing around the rim of your cooled cookie cake -- I used a piping bag fitted with a Wilton 2D tip, but in a pinch you can simply transfer your frosting to a ziploc bag, snip off a small corner, and pipe that way. Top frosting with sprinkles for decoration
