Rainbow Jello

If you’ve ever wondered how to make rainbow jello – you’re in the right place. It’s much easier than you might think and the only hard part is the waiting for each layer to set up.

They layers are absolutely magical and as wonderful as they are to look at, they’re even more fun to eat.

Rainbow JELLO Cubes Recipe (2)

This particular recipe just happens to work for St. Patrick’s Day! It’s so fun to make and easy too! The boys love picking out their favorite flavors of jello and then I put it all together. I say jello “flavors” but really they go by color. You know…”the red jello” or “the green jello”. Whatever works ?

Not only is this dessert beautiful and super-impressive {it looks like it’s really hard to make} but it’s easy on the wallet as well.

You only need some jello, a can ofsweetenedcondensed milk, and some unflavored gelatin. Easy peasy! You can choose whatever colors you like which makes this a very versatile dessert. Layer in the colors of your next party and you’re going to have a yummy treat that’s sure to be a hit!

There’s just something aboutrainbow jellothat bring a smile to my face every time. My boys are also thrilled when I “make rainbows” in the kitchen – they are also HUGE jello fans so this treat is a win-win for everyone.

You can really cut down the calories and sugar in this dessert by using sugar-free jello and low-fat or fat-free sweetened condensed milk. Oh and did I mention this recipe makes TONS of cubes?? Like literally, tons. Depending on how precise I am with my cutting, I usually end up with between 60-80 cubes so there’s plenty for a crowd OR class!
