Rainbow jello is simple layered jello in different colors, one layer atop the next. In this recipe they’re separated by a white layer made from a condensed milk mixture, but you can leave it out.

You use the same methods and ingredients whether you make it as individual cups, or in a pan to be cut later, or any other shape. Any recipe will work with any container.

How gorgeous is this Rainbow Jello in a glass? If you've been intimidated at the thought of trying to make rainbow jello, it's not hard at all. It's just time-consuming - not gonna lie. But kids love it. And serving it in these glasses is a lot of fun. There's just something special about making individual portions in glasses.

Ingredients

  • 6 small packages of jello in various colors
  • 5 packages Knox unflavored gelatin
  • 2 14 ounce cans of sweetened condensed milk
  • Water

Instructions

  1. For the first layer, mix a package of jello with 1 teaspoon of the gelatin and a cup of boiling water. Cool and pour into the bottom of each glass. Refrigerate until set (about 30 minutes).
  2. While waiting for that to set, make your second layer of gelatin mixture and let it be cooling on the countertop.
  3. For the second layer, mix an envelope of gelatin with 1/2 cup hot water until it dissolves. Add 1/2 can of condensed milk and another 1/2 cup of hot water. Once your first Jello layers have cooled, bring them out of the refrigerator and pour this mixture over them in a thin layer. Refrigerate again until firm.
  4. While that's setting in the fridge, go ahead and follow step 1 again to make a new layer of jello. And so on and so forth until you're done creating the layers and the dessert has set.

Notes

Once it's set, it's still a good idea to leave it in the fridge overnight.
