The jiggliest, most colorful and whimsical treat of all, this Layered Rainbow Jello is the perfect finger food for parties. This finger jello a total crowd-pleaser and it’s fun and easy to make.

Every time I make rainbow jello and take it somewhere, kids and adults alike go crazy for it. It’s basically impossible to resist these sweet, fruity, jiggly little cubes of color.

I was thinking that these would be fun for St. Patrick’s Day, even though I’ve made them more often for school parties or birthday parties with a rainbow party theme and that sort of occasion. They set up like Jello Jigglers (remember those?!) so they are the perfect finger jello to pick up and pop in your mouth.

Is making layered Jello hard?

It’s not difficult to make rainbow jello, but it is a little bit time consuming. Each layer needs to set before adding the next, and you need to let the jello cool so hot jello isn’t poured on top of the previous layer, which will cause it to melt and make the layers cloudy. If you look closely in these pictures, you might notice that I rushed the blue and green layers just a little bit too much this time around. They aren’t terrible, but not totally perfect. Either way the jello tastes awesome though.

How to Make Layered Rainbow Jello

When making rainbow jello, remember ROY-G-BIV for the order of rainbow colors – red, orange, yellow, green, blue, indigo, violet. Except we are skipping indigo since the only good blue option I know of for jello is the “berry blue” flavor.

1. Start with a colored bottom layer by stirring a 3-ounce package of flavored jello (I started with the purple grape flavor) with 1 teaspoon of unflavored gelatin into 1 cup of boiling water until completely dissolved. This is the only layer that you can go ahead and pour right into a 9×13-inch pan while it is still hot. Transfer to the fridge, making sure that the dish is sitting completely flat, and chill until completely set, about 30 minutes.
2. Make the next layer (the white layer) as soon as you put the first layer in the fridge. This will give it time to cool to room temperature so you aren’t pour hot liquid over the first set layer.
3. To make the white layer, dissolve 2 teaspoons (1 envelope) of Knox unflavored gelatin in 1 cup of boiling water. Add 1/2 can of sweetened condensed milk and stir to combine.
4. When the first colored layer has set, pour 3/4 cup of the white jello mixture (1/2 of the white gelatin mix, which will need to be made a couple of times to complete the jello) over the previous layer. Return the jello to the fridge so the white layer can set. I find the white layer sets really quickly – in about 20 minutes. So go ahead and make the next colored layer at this point as well to give it time to cool.
5. Continue to make layers, alternating flavored colorful layers with the creamy white layers, letting the jello set between each addition until all of the jello has been used up. If you find the white layer is setting up on the counter in between waiting for colored layers to cool, you can set it into a bowl of hot water and stir it a few times and it will liquify again as it warms and can then be used like normal. Because this layer is used 5 times, you will need to make 2 1/2 batches of the white layer to finish the jello.
6. Once the jello is completely set, slice into 1-inch squares and serve. Be sure to use a paring knife, rather than a serrated knife, if you want to have clean cuts and edges on your jello cubes.
7. Use a small spatula to remove the jello from the pan. The first couple of cubes are always the hardest to get out cleanly, but after that it’s smooth sailing.

Layered Rainbow Jello

The jiggliest, most colorful and whimsical treat of all, this Layered Rainbow Jello is the perfect finger food for parties.  This finger jello a total crowd-pleaser and it's fun and easy to make.

Prep Time 15 minutes

Additional Time 4 hours

Total Time 4 hours 15 minutes

Ingredients

• 6 (3 ounce) packages different Jello flavors (Berry Blue, Lime, Lemon, Orange, Grape, and Raspberry, Cherry or Strawberry for red)
• 5 packages unflavored gelatin
• 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 you find the white layer is setting up on the counter in between waiting for layers to cool, set it into a bowl of hot water for 5 minutes and stir it a few times until it turns smooth and liquid again, then use like normal. Because this layer is used 5 times, you will need to make 2 1/2 batches total of the white layer to finish the jello.
