Cake Instructions
  1. Preheat oven to 350 degrees and spray cake pans with baking spray.
  2. Follow the directions on the back of the cake boxes to prepare the cake batter.

  4. Bake in the oven for 25-35 minutes or until a toothpick comes out clean.
  5. Allow to cool completely before icing and assembling.
  6. Remove the cakes from the cake pans and place them onto a cutting board.
  7. Place one cake onto the cake board and use the cake leveler to remove the dome from the cake.
  8. Repeat leveling with remaining two layers and set aside.
Frosting Instructions
  1. Using a standing mixer, combine all ingredients except the food coloring and beat until smooth and stiff peaks form.
  2. Scoop 1 1/2 cups of frosting into each of the 3 bowls.
  3. Mix in 1 color into each bowl.
  4. Scoop each color into its own piping bag.
  5. Scoop 2 cups of frosting into the green frosting bowl and add more green food coloring into the frosting. Mix until combined.
  6. Cut the tips off the three disposable piping bags.
  7. Using the green frosting, pipe a thick ring around the outer edge of the top of the first layer of cake.
  8. Pipe a thick ring of purple frosting on the inside of the green ring.
  9. Pipe a thick ring of orange frosting on the inside of the purple ring.
  10. Repeat these steps until you’ve filled the circle and can’t pipe any more rings.
  11. Place the second layer of cake on top of the first layer of frosting.
  12. Repeat the steps with the frosting rings.
  13. Place the third layer of cake onto the second layer of frosting.
  14. Using 1 3/4 cups of the green frosting, frost the entire cake.
  15. In a large bowl, combine all Halloween sprinkles.
  16. Coat the entire cake with the halloween sprinkles.
  17. Using the left over green and white frosting, scoop green frosting onto one side of the piping bag and the white frosting onto the other side, so you have two-colored frosting.
  18. Pipe dollops of frosting onto the top of the cake.
  19. Using the piping gel, pipe oozy drips onto the top of the frosting dollops.
  20. Place the cake into the refrigerator to allow the frosting to set before cutting into slices and enjoying!
