ingredients

  • 2 white cake layers, cooled (9-inch rounds)
  • 2 12 cups boiling water
  • 0.5 (3 ounce) package red gelatin
  • 0.5 (3 ounce) package orange gelatin
  • 0.5 (3 ounce) package green gelatin
  • 0.5 (3 ounce) package blue gelatin
  • 0.5 (3 ounce) package purple gelatin
  • 12 ounces whipped topping, thawed (Cool Whip)
  • 1 large egg white
  • 2 cups confectioners' sugar
  • 12 lemon, juice of
  • red green, blue, purple, orange food coloring

directions

  • Place cake layers, top side up, in two 9" round cake pans.
  • Pierce cake with skewers at 1/2" intervals.
  • Stir 1/2 cup of the boiling water into each flavor gelatin in separate bowls, stir for 2 minutes or until completely dissolved.
  • Start pouring each different color gelatin into the various holes in both cake layers. Only pour one color into each hole. Keep pouring until all holes are filled with color. Refrigerate 3 hours.
  • Dip 1 cake pan in warm water 10 seconds; unmold onto serving plate.
  • Spread with about 1 cup of the whipped topping.
  • Unmold second cake layer; place on first cake layer.
  • Frost with remaining whipped topping.
  • Refrigerate until whipped topping is firm.
  • Place egg white in a medium mixing bowl and beat with an electric mixer to form soft peaks.
  • Add icing sugar and lemon juice and stir with a spatula to combine.
  • You want your mixture to be a thick but still running paste, if it is too thin it will run right off the cake and if it is too thick it won't mix and drip down the sides.
  • Split mixture into 5 bowls and add color to each bowl (orange, red, purple, blue and green).
  • Carefully drizzle small amounts of each color over the top of the cake. Start from the center and work your way out, this makes it easier to gauge when there is enough icing for it to just start over-flowing around the edge of the cake.
  • Chill cake until ready to serve.

    Turned out great! I've never done a layer cake before and was a little intimidated, but this turned out to be easy. I followed recipe pretty closely except I used yellow instead of orange icing. My 6yo wanted a rainbow birthday cake, and she got one!! Next time I will add more pokes and jello - I was nervous it'd be a brown blob on the inside, but it wasn't! Be sure to NOT add the cold water step to your Jello, it thins out the colors. Just very slowly and carefully pour the hot Jello into the holes to minimize it running all over the top. I used a boxed white cake mix and it was super moist and crazy delicious. Best served cold, the icing starts to run once it's not cold. I had to add a tiny bit of milk to the icing mix, mine was a little to thick. Pay no mind to the intolerant review - this cake is awesome.

    What an awesome way to celebrate diversity. I made this cake for a Pride party and it was the centerpiece of the dessert table. Lots of ohh's and aww's. It really did turn out beautiful. It strikes me as so sad that the only other review for this cake was mad by a totally intolerant and hate-filled person who has no right to judge others, as her review insinuates.

    I added yellow to the recipe so the rainbow was represented even better.

    Rainbows don't mean what God gave them to us for anymore.
