Warmer weather is in the air, I hear the birds chirping again… and there is snow on the ground! Grrrr. I think I prematurely packed away all of our winter gear, but I am refusing to pull anything down from storage so my fingers will just have to put up with it.

You must have known that rainbow jello was in the works. First, we shared a recipe for cute Rainbow Donuts and I’ve been sharing a few recipes that use jello like melon kiwi layered jello cups and swimming peeps jello cups. So it’s time to combine rainbows and jello :)

And by recently I mean, until I made those ridiculous rainbow donuts. Now I want to make everything rainbow colored! I even ordered a rainbow cookie cutter and I’ve been having dreams about rainbow dipped twinkies. Weird.

Well, my ways have changed and I’m on board with rainbows. And fluffy kitties and unicorn poop cookies.

Eww, just kidding. But unicorn poop cookies (see here on pinterest) are a real thing, and being rainbow colored, I now like them, except someone had to go and ruin them by calling them unicorn poop cookies.

It’s great that jello comes in so many different flavors. For the yellow layer, instead of having to get lemon jello, which I’m not sure lemon jello would be very good, they offer island pineapple, which is what I used and it’s tasty! I also saw apricot, melon fusion, peach, and tropical fusion. Just pick the colors and flavors you want, and you’re ready to make rainbow jello!

  1. beth these are so great! and for not liking rainbows, you did an amazing job :)

  2. My girls would have a blast eating these!

  3. I love the way this looks! I am not big on jello but my kids are and they’d love this for sure!

  4. What a fun dessert and so pretty too! This would be great to serve up at a summer swim party.

  5. What a great idea with Easter coming up!

  6. Wow, I’ve never seen rainbow jelly before, ever! This is SO cool!

  7. You and your layered jello! Mine would never turn out this cute….

  8. We had a cold front come in too. After having temps in the high 70’s for almost a week, 23 degrees is a huge disappointment. I should just create my own spring with this color rainbow jello!

  9. I woke up this morning remembering my dream about sitting outside in the sun while working! I can’t wait for warmer temps and sunshine, even if it means we have to deal with a few rainbows. This jello is sooo cute!

  10. What a cute idea Beth! You always have such fun ideas and tasty treats!

  11. Super, super cute!! Love your rainbow donuts, too! The “poop” cookies…ummmm….. ;)

  12. These are utterly charming! I have a Rainbow Food pin board, so this is going on it!

  13. This is so adorable! I bet kids would love to dig into a bowl of rainbow jello :)

  14. Did this take forever?  Being you have to let each color set. My 5 year old granddaughter is OBSESSED with rainbows and this is on her activity agenda. 

    • Hi Jen! It doesn’t actually take much “hands on” time. A lot of the time is the jello setting because yes, you need to let each layer semi-set before adding the next. I think I made this recipes over a few days.

  15. Could you put sweets in between layers like a number made of smarties for a birthday or put them on top? Would they sink. Your squares look amazing

  16. I love this! I used to make them with a white layer separating colors. This looks (and I bet tastes) way better!

  17. I had all but the blue on hand (no idea where that blue one went!) to make rainbow jello when my one grandson would be coming for dinner and went looking for a recipe. I wasn’t crazy for any of the white layer between options as we have one who hates sour cream, another who detests evaporated milk… you get the picture … Came across you simple solution and knew it would be a hit. I layered it in an 8″ glass baking dish in rainbow order but starting with purple and ending with green so the blue wouldn’t be missed. I used 3/4 cup boiling water and 3/4 cup cold to give it more “body.” Love the fact I could fully chill each layer and the heat from the next was enough to fuse them but not so much to mix them. My orange package was a double size, so had I had all small packages including the blue it would have filled the 8″ square pan the same – perfectly! My 3-1/2 year old great grandson took a bite, his face lit up and he announced, “I LIKE this!” He and his 2-1/2 year old brother had seconds and thirds, even after they had eaten supper and birthday cake. Guess “there’s always room for jello” still stands.
