What is a Watermelon Cake?

This cake isn’t a cake at all! It is simply a watermelon sliced into a cylinder and covered in whipped cream or whipped topping. It looks like a cake but is a deliciously fruity dessert!

VARIATIONS: Sprinkle on some blueberries (for a red, white, and blue holiday theme) or some sliced strawberries for a pop of color. Add sprinkles if you’d like.

Drizzle with chocolate sauce. Don’t forget the chopped mint as a colorful garnish! For an extra fancy topping, sprinkle on a few rose petals!

  • Cut the ends off of the watermelon so it can stand upright.
  • Using a sharp knife, trim off the rind. Finally, trim around the watermelon to give it a "cake" shape.
  • Once cut, use paper towels to completely dab the watermelon dry. You don't need to squeeze it but you want the surface as dry as possible.

  • Frost the watermelon with the dessert topping using an offset spatula.
  • Use berries or topping of your choice to decorate your cake.

Recipe Notes

Note: Using Cool Whip Light, the topping did NOT slide off my watermelon even after a couple of days!
