Rainbow Jello
This rainbow layered jello is a fun treat for a rainbow themed party, Saint Patrick’s Day or for Easter. Made with sour cream, this colorful and jiggly rainbow themed dessert is a favorite with kids and grownups alike.

This dish could be one of those holiday staples that everyone anticipates and everyone remembers. I know some people might think all those Jello flavors might taste weird mixed together but it doesn’t!
They blend really well together and I have to say that I was excited to get sent home with the extra pan of Jello. I certainly ate my fair share. And my kids chose to eat the Jello over leftover pie almost every day for a week!
Rainbow jello is a perfect treat to bring when you need something for a big gathering. It makes a lot! It also works equally well for a brunch, party or dessert.
Ingredients
FOR A 9X13 GLASS PAN AND A 7X9 GLASS PAN
- 6 flavors of Jell-o, 2 small boxes of each flavor for 12 boxes
- 4 cups sour cream
FOR TWO 9X13 PANS
- 7 flavors of Jello, 2 small boxes of each flavor for a total of 14 boxes
- 5 cups sour cream
I recommended these flavors but feel free to use whatever you want, just keep in mind the rainbow colors, ROYGBIV- watermelon, strawberry or cherry, orange, pineapple or lemon, lime, berry blue, and grape.
You’ll also need a tub Cool Whip for topping if you want.

How to make this
Step 1: For 1st layer
- Empty 1 small box of Jello into a small glass bowl. Add 1 cup boiled water to jello. Stir until well dissolved.
- Add 2/3 cup sour cream and whisk until well blended.
- Pour mixture into both glass pans, place in the fridge making sure they are level, and chill until set, about 30-45 minutes.
Step 2: For next layer
- Repeat with the same flavor, adding 1 cup boiled water and 1/3 cup cold water to jello.
- Let stand for 10 minutes. Pour onto the chilled 1st layer, tilting the pan if necessary to spread, and refrigerate until set.
Repeat layers
Continue repeating layers following steps 1 and 2, alternating one with sour cream then one without until each flavor is used.
To serve
- Once the jello is completely set, slice into 1-inch squares using a paring knife and serve. Using a small spatula will help you get the jello cubes out of the pan.
- If desired top with Cool Whip.
Top Tips
Is this hard to make?
The process is very easy but it is time consuming. The key thing to have these turn out well is to leave enough time for each layer to completely set up before adding the next one. Trying to rush the process will get you into lots of trouble.
The other key to getting nice even layers is to make sure that the dish is placed level in the refrigerator while it sets. If it’s not level you’ll get wonky layers that won’t look nice when cut into.
Can I freeze this?
NEVER freeze jello! It can be tempting to make this ahead and try to freeze it but when you freeze jello the chemical structure breaks down and the whole thing will begin to melt.
This is best made no more than a day ahead as I have found the jello starts to weep liquid after that.

I decided to switch things up a bit and went with Cool Whip instead of sour cream. Let me tell you, it turned out absolutely delicious! Thanks a million for sharing this amazing recipe with me. Oh, and by the way, I made a smaller portion since I only needed to serve three people. Perfect!
Think I could use yogurt instead of sour cream? Thanks.
I would use plain Greek yogurt in place of the sour cream. Regular yogurt tends to be a little more liquid.
This is delicious my son in law makes and everyone loves it, thanks for sharing I am pinning so I can make it next time.
This might be time consuming, but the result is so worth it! I want to make it sometime, it looks so cool! Thanks for sharing this recipe with Hump Day Happenings.
