This fun & fruity rainbow jello will be a hit with everyone! 12 layers of Jell-O and some whipped cream make this so colorful and tasty. It’s surprisingly easy. Anyone can do it!
This rainbow jello brings back many memories because my mom used to make it for us. I remember her doing layer by layer and spending all that time making it, and then being so excited to finally be able to dig in.
I know this may look like it’s too hard to make, but I promise you that if you can boil water, measure water, open a Jello pack, stir, and add cool whip then you can make this rainbow jello 🙂 The hardest part about it is the time commitment. Each layer needs to sit in the freezer for at least 15 minutes. So, 12 layers x 15 minutes = 3 hours of freezer time. You obviously can be doing other things while it freezes, but make sure you make this on a day that you have that amount of time at home.
I made this in an 8×8 baking dish because I wanted a really thick rainbow jello, but I have also made this in a 9×13 dish, a 9×9 dish; you can really use any dish you want. Just remember that it is 12 layers, so you do want to use something that could hold that.
The steps to making this are fairly easy and they’re the same for each layer:
Mix the Jello package with 1 cup boiling water. Stir until dissolved.
Pour 1/2 cup of that mixture into the smaller measuring cup and then add 3 tablespoons cold water. Stir.
Add 1/3 cup cool whip into the hot water mixture and then stir with a whisk until combined and “cloudy” looking,
Pour the “cloudy” mixture into the bottom of the pan. Stick in the freezer for 15 minutes.
Take it out. Add the other jello mixture (the one you added cold water to) on top of the creamy mixture that you just pulled from the freezer. Put back in the freezer for 15 minutes.
Repeat with remaining colors.
The name brand of Jell-O seems to set up better. I suggest buying the Jell-O brand.
If you don’t want to use cool whip you can use anything that will create a “creamy” or “cloudy” effect; greek yogurt, plain yogurt, vanilla yogurt, sour cream. I just prefer the cool whip because it’s light and we love the bit of sweetness it adds.
The first 2-3 layers will take longer in the freezer because the pan is not cold yet. The layers after may only need about 12 minutes in the freezer because everything will be colder.
You can also put it in the fridge but it will take much longer to set up. I’m guessing around 30 minutes + for each layer.
I’ve made these in individual clear plastic cups as well (the larger clear plastic cups; 9 oz I believe). It makes about 7 of those cups.

- For each layer, add 1 cup of boiling water to the package of Jello. Stir and dissolve Jello.
- Pour 1/2 cup of it into a small glass measuring cup. Add 3 tablespoons cold water to it. Stir.
- Using a whisk, stir 1/3 cup cool whip into the other half of the Jello (the half that has the boiling water in it). Stir until combined.
- Pour the creamy Jello layer into your dish. Put in freezer for 15 minutes or until the layer is set.
- When the first layer is set, pour second layer on it.
- Repeat process for remaining packages of Jello. Pour creamy layer first and then the clear layer. You should end up 12 layers.
