Rainbow Jello Jars

Updated: May 11, 2019

Beautiful jars of rainbow jello that are just as tasty as they are pretty! A great option for allergy friendly individual serving desserts that kids and adults alike are sure to love!

Ok, not gonna lie, these are super easy to make but take a long time to assemble because they need to sit in the fridge after each layer is added (and there are 12 layers). Not the kind of thing you want to make if you're in a rush, but super easy to do on a day that you can go back and forth between the kitchen and chores (or watching tv! I hope it’s watching tv and not chores).

The jars I used to make these hold 1/2 cup and I ended up filling 11 of them. The thing is though... I only used half of each packet of jello mix. I didn't have enough little jars and making 6 full packets of jello is a lot to eat! I split them in half using a kitchen scale and saved the other halves of each packet for later use.

If your serving cups hold significantly more or less than 1/2 cup, you’ll want to adjust how much you measure out for each layer, and the number of servings you make will also change.

You may also find that your grocery store is missing one of the jello colours you need... I had this happen with blue. The good news is that there’s a really easy workaround! Get yourself some Gatorade or other similar sports drink in the appropriate colour and some unflavoured gelatine powder and you’re good to go (see recipe notes for details on how to use this).

Makes 10-12 servings


  • Half each of 85g / 3 oz packages of jello in purple, blue, green, yellow, orange, and red (flavours of your choice) *

  • 6 tbsp vanilla yogurt (divided)

  • Whipped cream (optional)

  • Sprinkles (optional)


  1. Place jello powder for each colour in its own mug (needs to be big enough to comfortably fit 1 cup of liquid). Line colours up in the order you’ll use them so you don’t lose track of which is next.

  2. Boil at least 3 cups of water. Add 1/2 cup of boiling water per mug of jello powder and stir until dissolved.

  3. Add 1/3 cup of cold water to each mug and stir.**

  4. Measure out 3/8 cup (6 tbsp) of your first colour into a new mug and set the rest aside. Add 1 tbsp of vanilla yogurt to the 3/8 cup jello liquid you measured out and stir until yogurt is dissolved.

  5. Measure out 2 tsp of the yogurt mixture into each serving container and then transfer them all to the fridge taking care not to jostle them or tip them too much. Refrigerate for 15-20 minutes until no longer liquid. The first few layers may take a bit longer to set since the liquid will be warmer.

  6. Measure out 2 tsp of the non-yogurt mixture of the first colour (the part you had set aside) into each serving container. If you find that the layer below looks a bit like it's rippling or you see any mixing when you're adding the next layer then stop and put them all back in the fridge for 5 minutes so the previous layer can set up a bit more. Refrigerate for 15-20 minutes until no longer liquid.

  7. Repeat steps 4-6 for each subsequent colour. If you notice that any of the colours are starting to set up on the counter, you can put a bit of boiling water into a bowl and put the whole mug into the water to warm it up a bit.

  8. When all layers have been completed, refrigerate for 3 hours to fully set.

  9. To serve, top with whipped cream and sprinkles if desired.


* Not sure what to do with the other half of those jello packets? Why not make playdough with them! Just make half of the linked recipe for each colour.

** If you're using Gatorade and unflavoured gelatine powder you'll want to measure out 1/2 tbsp of gelatine (1/2 an envelope) and put that in a mug. Heat 1/2 cup of the Gatorade in a small saucepan until bubbles are just starting to form then add this to the gelatine powder and stir until combined. Add 1/3 cup of cold Gatorade to the mixture and you're ready to make jello.
