Ingredients

For the Cake:

  • 2 boxes of triple chocolate cake mix 
  • 6 large eggs
  • 2 Cups whole milk
  • 2/3 Cup unsalted sweet cream butter, softened 
  • 3 9 inch round cake pans 
  • 1 10 inch round cake board

For the Chocolate Frosting:

  • 4 Cups unsalted sweet cream butter, softened
  • 1 Cup Hershey’s cocoa powder
  • 8 Cups powdered sugar
  • 1 tsp vanilla extract
  • 1 large piping bag fitted with a star tip

For the Garnish:

  • Cosmic Brownies
  • 3 Cups of chocolate rainbow crunch sprinkles

Instructions

  • Preheat oven to 350 degrees and spray cake pans with pam baking spray, set aside.
  • Using a standing mixer or hand mixer, beat together the cake mix, eggs, milk and butter until smooth and combined. Split the batter between the 3 pans and bake for 25 -30 minutes or until a toothpick comes out clean. Once baked, remove from oven and allow to cool completely.
  • Using a standing mixer or hand mixer, beat all ingredients until combined, smooth and stiff peaks form. Scoop about 1 1/2 C frosting into the piping bag and set aside.

Building the cake directions

  • Using the cake leveler, cut the domes off the cake rounds to make them leveled. Place one cake round onto the cake board. Scoop 1 1/2 C of the chocolate frosting onto the top of the cake and smooth evenly with the angled spatula. Place another cake round on top of the first one.
  • Scoop another 1 1/2 C of the chocolate frosting onto the second cake round and smooth evenly. Place the third cake round on top of the second one. Scoop remaining chocolate frosting onto the top of the cake and frost entire cake.
  • Place cake on a cake stand in the middle of a cookie sheet. Sprinkle some of the rainbow sprinkles around the bottom of the cake.
  • Place cake into the fridge for an hour to allow the frosting to firm up. Pipe dollops of chocolate frosting along the top of the cake.
  • Place a piece of cosmic brownie in between the chocolate frosting. Sprinkle some more rainbow sprinkles around the top. Cut into slices and enjoy!
