Chocolate ganache

Instructions

  • Preheat oven to 350 degrees and spray the cake pans with pam baking spray.
  • Following the directions on the back of the cake boxes, make your cake batters.
  • Fill 1 cake pan 3/4 way full with one flavor batter for each pan.
  • Bake in the oven for 25-30 minutes or until a toothpick comes out clean.

Frosting Directions

  • Using a standing mixer, beat all frosting ingredients together until combined and smooth and stiff peaks.
  • Scoop 1 1/2 cups frosting into the piping bag and set aside.

Assemble

  • Remove cakes from the pans and use the cake leveler to remove the dome tops.
  • Place the strawberry layer onto the cake board. Add a layer of slice bananas and scoop 1 1/2 cups of frosting onto the top of the cake and smooth evenly with the angled spatula.
  • Place the chocolate cake layer and add another layer of sliced bananas. Scoop another 1 1/2 cups frosting onto the top of the chocolate layer and smooth evenly.
  • Place the vanilla cake layer on top of the second layer of frosting.
  • Using the remaining frosting, frost entire cake.
  • Cover the bottom of the cake with the sprinkles.

Chocolate ganache directions

  • Using a small pot, heat up the heavy whipping cream until steaming.
  • While heavy whipping cream is heating up, place chocolate chips into a heat-proof bowl.
  • Once the heavy whipping cream is heated, pour over the chocolate chips.
  • Allow to sit for 1 minute before whisking until smooth.
  • Pour ganache into the squeeze bottle.
  • Pipe drips of the ganache around the edge of the cake and fill in the top middle of the cake with ganache.
  • Place the cake into the fridge for 30 minutes to allow the ganache to harden.

  • Sprinkle some chopped peanuts.
  • Top the frosting dollops with cherries.
