Equipment

  • Two 8-inch round baking pans for baking the cake layers
  • Electric hand mixer for whipping the frosting
  • Whisk for dissolving the jello
  • Wire rack for cooling the cakes
  • Large bowls for mixing the jello and whipped topping

Ingredients
  

  • 1 box white cake mix

Jello Frosting

  • 32 oz whipped topping
  • 2 cups boiling water
  • 4-3 oz boxes jello, any flavors

Instructions
 

  • Start by baking the cakes in two 8-inch round pans according to the instructions on the box.
  • After baking, let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.
  • As the cakes cool, prepare the frosting one color at a time.
  • Dissolve each packet of jello in a large bowl by whisking it with 1/2 cup of boiling water.
  • Repeat this process for all four colors.
  • Allow the jello mixtures to cool for about 10 minutes.
  • Next, whisk 1 1/2 cups of whipped topping into each bowl of jello.
  • Cover the bowls and refrigerate them for 2 hours.
  • After chilling, use an electric hand mixer to break up the mixtures.
  • Then, add another 1 1/2 cups of whipped topping to each bowl and whip until smooth, leaving a few small lumps.
  • To assemble the cake, slice each cake layer in half horizontally.
  • Place the bottom half of one layer on your serving platter.
  • Reserve about 1/4 to 1/3 cup of your first jello frosting, and spread the rest over the cake layer.
  • Place the top half of the cake layer on top. Repeat this process with the next color of jello frosting.
  • Add the next cake layer, this time placing the top side down.
  • Frost with your third jello color.
  • Finally, place the last cake layer on top, bottom side up, and frost with the remaining color.
  • For the ombre effect, dollop the remaining frosting around the outside of the cake.
  • Use a bench scraper or offset spatula to smooth the frosting evenly.
  • Place the cake in the refrigerator for at least one hour to set, then serve.

Notes

  • Make sure your cake is at room temperature before applying the Jello mixture.
  • Experiment with different Jello flavors to create a unique and flavorful cake.
  • Chill the cake in the fridge for a few hours to make slicing easier.
  • Keep frosting layers smooth for a beautifully presented slice.
