Hot tub cake recipe

Ingredients:

  • 1 (15.25 ounce) box yellow cake mix
  • 1/3 cup vegetable oil
  • 3 large eggs
  • 9 Kit Kat candy bars broken into 36 segments
  • 2 (16 ounce) containers blue frosting (or vanilla frosting tinted with blue food coloring)
  • 20 inches black ribbon
  • 3 Barbie dolls, legs removed

Directions:

Bake two round cakes following the directions on the box. Once the cakes have been baked and cooled, you can start assembling.

1. Place a dollop of frosting on your base, which can be a cake board or a cake stand.

4. Frost the sides, making sure that there is enough frosting to hold the Kit Kats in place but not so much that it squishes out when the candies are placed.
