Ingredients

For the cookie cake:

  • ¾ cup salted butter melted
  • 1 cup light brown sugar
  • ¼ cup granulated sugar
  • 2 tsp vanilla extract
  • 2 eggs room temperature
  • 2 cups all-purpose flour
  • 1 tbsp corn starch
  • ½ tsp baking soda
  • ½ tsp salt
  • ¾ cup chocolate chip I prefer milk chocolate or semi-sweet but you can use whatever you like!
  • ¾ cup M&Ms
  • ½ cup sprinkles

For the frosting:

  • ¾ cup salted butter room temperature
  • 4 cups powdered sugar
  • 1 tsp vanilla extract
  • 3-5 tbsp heavy cream room temperature
  • ½ tsp salt
  • food dye I use purple, green and orange
  • candy eyes

Instructions

For the cookie cake:

  • Preheat the oven to 350° and grease and line the base of a 10 inch springform pan with parchment paper. In the bowl of a stand mixer combine melted butter, light brown sugar, granulated sugar, vanilla extract and eggs. Mix on medium speed for 30 seconds until combined.
  • With the mixer on low add in the flour, corn starch, baking soda and salt. Mix on low until incorporated. Remove the bowl from the stand and fold in the chocolate chips, M&Ms and sprinkles with a spatula. Spread the cookie dough in the prepared pan and bake for 25-30 minutes or until the cookie is lightly browned and looks dry on the surface. Allow to cool completely before frosting.

For the frosting:

  • In the bowl of a stand mixer beat together the butter and powdered sugar for 2-3 minutes until combined and smooth. Add in the vanilla, salt and 2 tablespoons of heavy cream and beat until smooth. Add in additional heavy cream to get the consistency you prefer. Once smooth, divide the frosting into 3 separate bowls. Add in 1-2 drops of coloring in each bowl, one purple, one orange and one green. Prepare 3 piping bags with different tips tip (I used a large Wilton #8B, one Wilton #233, and one Wilton #4B) and pipe alternating colors along the edges. Top with additional candy eyes and slice and serve!
