Rainbow Jello Recipe
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.
You can pick the colors and flavors you would like to use to make your rainbow jello. I went with red, orange, green and blue for this batch. Feel free to make as few or many layers as you like.
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 of sweetened condensed 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 about rainbow jello that 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!
How To Make Rainbow Jello
Rainbow JELL-O Cubes
Ingredients
- 4 packages 3 ounces each assorted flavored gelatin
- 1.5 oz unflavored gelatin divided
- 5-3/4 cups boiling water divided
- 14 oz sweetened condensed milk
- 1/4 cup cold water
Instructions
- In a small bowl, combine one package flavored gelatin and one envelope unflavored gelatin. Stir in 1 cup boiling water until dissolved. Let mixture cool slightly for 3-5 minutes.
- Pour mixture into a 13-in. x 9-in. dish coated with cooking spray.
- Refrigerate until set but not firm, about 20 minutes.
- In small bowl, combine the condensed milk and 1 cup boiling water.
- In another bowl, sprinkle two envelopes unflavored gelatin over cold water; let stand for 1 minute. Stir in 3/4 cup boiling water. Add to sweetened condensed milk mixture.
- Spoon 1 cup of the creamy gelatin mixture over the first flavored gelatin layer. Refrigerate until set but not firm, about 25 minutes.
- Repeat from beginning of recipe twice alternating flavored gelatin with creamy gelatin layers.
- Make sure to let the dissolved gelatin sit for a few minutes before spooning over previous layer. This will keep the layers “pure”.
- Chill each layer until set but not firm before spooning next layer on top.
- Make final flavored gelatin and spoon over top.
- Refrigerate for 2 hours after finishing last layer before cutting into 1-in. squares.
- Serve and enjoy!
