Rainbow Jello. Wow your kids with this layered Jello dessert recipe. Step-by-step instructions on how to make this fun treat!
Today, I have another fun project we did last year for St. Patrick’s Day. Since many people decorate and do crafts with rainbows for St. Patrick’s Day, I thought making rainbow jello would be fun!
UPDATE: Check out my NEW quick set recipe for rainbow jello!
How to Make Rainbow Jello
Supplies:
- 6 Packages of Jello (red, orange, yellow, green, blue, purple – flavors of your choice)
- Clear Cup or Bowl (tall and skinny ones work best)
This recipe is fairly straightforward but it does take some time to make. If you want a faster method, check out my quick-set rainbow jello recipe.
Start by making the first color of jello according to the package directions. After you have made the jello, pour a small amount into each of your cups.
You can either start with red or purple, depending on which direction you want your rainbow.
Let each layer of jello set up for 30 minutes to an hour before you add another color, or your colors will just blend together.
Pour your next level of jello very slowly and carefully. If you have more time, this method is easier than the quick set to keep the layers separate.
Keep adding layers of jello and letting them set until you have all six colors in your cup. Then, top with a whip cream ‘cloud’ (totally optional) and enjoy!
Helpful Tips on Making Rainbow Jello:
- I would recommend making one large pan of rainbow jello rather than individual cups. Prepare the recipe for Jello Jigglers (where you use half the amount of water). Pour each layer into a large rectangular pan. Follow the instructions above. After all the layers have been made, cut it out into bars and top with whip cream.
- If you are going to do this project, be aware it makes a LOT of jello! This would be a great project to do for a party or another event where you will have more than 2 children eating the jello.
- Small, skinny, tall cups work best. Otherwise, you end up with so much jello in one cup.
- This was a fun project and I think it turned out really cute, but it is really time-consuming and not something I plan on doing every year.

Hi. I don’t know what I did wrong, but my colours blended. I think I used little yellie and didn’t let the new batch cool to room temperature before I started.

You definitely need to let each layer set up a bit before adding the next one. Since you are adding hot jello to cooled jello, if you don’t wait for the previous layer to cool, the colors will run. It is a slow, but necessary process.

My daughter really loved this. It was lots of work but it was worth it. She wants this made for all the kids at her next birthday party. I am not so sure about that.
