  • For the Cake
  • 1 box Double Chocolate Cake Mix
  • 1 1/2 c. Orange Fanta
  • 1 egg white
  • 6 crushed OREOS
  • For the Whipped Topping
  • 1 c. Whipping Cream
  • 3 Tbs. sugar
  • 1/2 c. Marshmallow cream
  • For the Orange Fanta Slime
  • 1 c. Orange Fanta
  • 2 tsp. corn starch


  • Combine cake mix, orange fanta and egg white. Mix on medium until no longer lumpy.
  • Add to greased baking pan, top with crushed OREOs, then bake according to cake mix instructions, then let cool.
  • For the Orange slime, pour Orange Fanta into a small bowl, then whisk in corn starch.
  • Heat a pan to medium heat, then add Fanta mixture.
  • Turn up heat and bring to a boil, then turn heat down to low. Let it cook for about 1-2 minutes, stirring often until it thickens. Remove from heat and refrigerate.
  • While cake and slime is cooling, whip whipping cream in a mixer until it starts forming peaks, for about 2-3 minutes. It needs to be stiff, but don't wait too long or it will turn to butter.
  • Once it's thickened, add sugar and marshmallow cream and whip until combined.
  • Pipe or spread whipped topping over cake, top with slime and more crushed OREOs and serve!
