This rainbow colored dessert has a layer of cake that’s made out of white cake mix, water, vegetable oil, and eggs. To bring the colors to life you’ll need boiling water and four boxes of jello mix.
For this recipe I used strawberry, lemon, blue raspberry, and lime jello. Feel free to choose whatever colors or flavors of jello you and your family like though!
