Layered Rainbow Jello

Layered Rainbow Jello is a multicolored gelatin dessert made by alternating flavored jello layers with sweetened condensed milk gelatin layers. Each colored layer sets before adding the next, resulting in a visually striking, firm, and creamy layered snack or dessert. The use of unflavored gelatin strengthens each layer and ensures a consistent, sliceable texture.

Description

Layered Rainbow Jello combines various flavors of colored jello—such as grape, berry blue, lime, lemon, orange, raspberry, or strawberry—with white layers made from sweetened condensed milk and unflavored gelatin. Each colored jello layer powder is dissolved with some gelatin in boiling water and chilled until firm in a flat pan. The white layer is prepared separately with gelatin and condensed milk to add a creamy contrast between the vibrant colors.

The process requires careful timing so each layer sets completely before pouring the next, preserving sharp, distinct layers that give the dessert its characteristic rainbow effect. The white layers also add a smooth texture and balance the sweetness and tanginess of the fruit-flavored gelatin layers.

This dessert is a festive treat that can be served chilled in slices, offering a fun mix of fruity and creamy flavors in every bite. It is suitable for celebrations or casual gatherings where a colorful, cool dessert is appreciated.

According to the notes, the white gelatin layer may sometimes start setting while waiting for layering; reheating it gently in hot water restores its smooth consistency. Multiple batches of the white layer are required to complete the full multi-layered dessert.

Ingredients

Servings
  • 6 jello 3 ounce packages, flavors: Berry Blue, Lime, Lemon, Orange, Grape, Raspberry, Cherry, or Strawberry for red
  • 5 packages gelatin unflavored
  • 1 1/2 (14-ounce) cans sweetened condensed milk
  • 8 1/2 cups water

Instructions

  1. Bottom (purple) layer: Dissolve a 3-ounce package of grape flavored jello with 1 teaspoon of unflavored gelatin (1/2 envelope of Knox unflavored gelatin) in 1 cup of boiling water by stirring until completely dissolved. Pour into a 9x13-inch pan and transfer to the refrigerator. Make sure the pan is sitting completely flat.  Chill until completely set, about 30 minutes.
  2. Second (white) layer: Make this layer at the same time as the bottom layer. Stir 2 teaspoons (1 envelope) of Knox unflavored gelatin in 1 cup of boiling water until dissolved. Add 1/2 can of sweetened condensed milk and stir until combined. Let this sit out on the counter until cooled to room temperature, but not yet set while the previous layer sets up in the fridge.
  3. Once the first colored layer has set, make the next colored layer (berry blue) following the directions in Step 1 so it can start to cool. Then pour 3/4 cup of the white jello mixture over the colored layer and gently tilt the pan side to side for even distribution. Return jello to the refrigerator to set up, which takes about 20 minutes. 
  4. Continue to make layers following steps 1 & 2, alternating flavored colorful layers (the next colors in rainbow order are green, yellow, orange, and red) with the creamy white layers, letting the jello set between each addition until all of the jello has been used up. You will need to make the white layer a couple of times because even without refrigeration it will set up on the counter if you make it all at once.  
  5. Once the jello is completely set, slice into 1-inch squares using a paring knife (not a serrated blade which leaves marks in the jello) and serve. A small spatula will help you get the jello cubes out of the pan.

Notes

  • If the white layer starts to set before layering, warm it gently in a bowl of hot water for 5 minutes and stir until smooth to use again.
  • Prepare about two and a half batches of the white gelatin layer to complete all layers in the recipe.
