Rainbow J-E-L-L-O Cake!


Rainbow Jell-O Cake
Yesterday was my hubby’s birthday, and every year he orders the same cake.
A Rainbow Jello Cake!
With grape Jello, and one other flavour that the kids get to pick…this year they chose lime!
(a secret yeay!  from Mom, because lime is my fave!)
 – – – 
This is such a fun cake that most people love!
You can’t seem to go wrong with Jello, white cake, and whip cream!  Yeeuuum.

Rainbow J-E-L-L-O Cake!
Save Recipe


  • 1 white cake mix (2 layer cake, no pudding)
  • 2 packages of Jello (2 different flavours)
  • 2 cups boiling water
  • whipping cream (you can use real whipping cream or cool whip)


  1. Bake your cakes according to the package directions, for a 2 layer cake. Tip! I spray the pans with cooking oil spray, then I line the bottoms of the pans with a circle of wax paper. From my experience with this cake, this is a necessary step! It can be so hard to get the cake out.
  2. Once the cakes have been baked, remove them from the oven, and let cool for 15 minutes.
  3. In the mean time, its Jello time! ** See the image above for more help! **
  4. Get out 2 glass measuring cups or bowls.
  5. Add 1 cup of boiling water to each bowl.
  6. Add 1 package of Jello to one bowl, the other package of Jello to the other bowl.
  7. Stir to dissolve.
  8. Once your cakes have cooled for 15 minutes, use a fork and poke holes all over them. Make sure you poke your holes deep so the Jello can get all through the cake.
  9. Pour your Jello over your cakes, one flavour on each cake.
  10. Refrigerate for at least 4 hours. You can leave them un-iced overnight in the fridge.
  11. After they have refrigerated, un-mold them, and frost with whipping cream.

  30. MMMMM This looks amazing!

    I would love if you would come share with Blog Stalking Thursday at The Crafty Blog Stalker.

  31. That is so much fun…I Love it!

  32. This recipe is even easier if you simply divide the cake mix in half, mix one packet into each half and them bake. Turns out pretty much the same.

  33. I’ve been making these jello cakes for decades, although have never tried grape!!… Orange and lime is a great combo, too. I’ve also made a one layer sheet cake with 2 packages of strawberry jello. Then I stir sweetened sliced strawberries (from the frozen food aisle – thawed) including the juice, into the whipped topping before icing cake (you have to refrigerate it again for the topping to ‘firm’ up again)…. it makes the icing pink! YUM!… love these cakes!
