Recipe Instructions

Step 1

Preheat the oven to 350 degrees F (175 degrees C). Line a 9-inch round cake pan with parchment paper and spray with cooking spray.

Step 2

Combine butter, brown sugar, and white sugar in a large bowl. Beat with a mixer until light and fluffy. Add eggs, one at a time, beating well after each addition. Stir in vanilla. Mix in flour, baking soda, and salt on low speed until just combined. Fold in chocolate chips and rainbow sprinkles.

Step 3

Press cookie dough into an even layer in the prepared pan and top with more chocolate chips and sprinkles, if desired.

Step 4

Bake in the preheated oven until golden, about 25 minutes. Remove from the oven and let cool in the pan for 15 minutes, then transfer to a cooling rack to cool completely, about 30 minutes.

Step 5

Mix frosting and food coloring. Transfer to a piping bag fitted with a large star tip. Pipe frosting around the edge of the cooled cookie cake. Slice into wedges to serve.
