Impress your friends and family with Rainbow Jello – a delicious and beautiful treat. Follow this recipe with a few simple tips and tricks to get the best layered Rainbow Jello ever!
The first time I saw Rainbow Jello, I thought my eyes were playing tricks on me. Not only that, but it tasted so good – better than it looked even which was really saying something! I remember thinking “I love this but I will never make it. It looks too complicated.” Layered Jello just looked really intimidating to make.
Well, friends, let me tell you. This treat is not very complicated, but it is time-consuming! However, the reaction on my kids’ faces when they saw this Rainbow Jello was totally worth it! So I will definitely be making this again, and I may do some different holiday-themed types soon. In the fall, you should try this Candy Corn Jello I made a few years ago. They were also a hit and less work! Another amazing Jello-ish recipe we have is this Orange Creamsicle Fluff. The reviews speak for themselves!

Rainbow Jello
Ingredients:
Red Jello (raspberry, cherry, strawberry)
Orange Jello (orange, peach)
Yellow Jello (lemon, pineapple)
Green Jello (green apple, lime)
Blue Jello (blue raspberry, blueberry)
Purple Jello (grape)
Unflavored gelatin
Sweetened condensed milk
This recipe is made with 3 oz. boxes of Jello and 14 oz. cans of sweetened condensed milk.
Flavors I used: Raspberry, Peach, Pineapple, Green Apple, Blue Raspberry, Grape
Layered Jello Directions:
Step 1: Jello layer
- Mix 1 tsp unflavored gelatin powder with one package (3 oz) of jello powder.
- Pour 1 cup boiling water into the powder and stir until powder is dissolved.
- Pour jello mixture into a baking dish or individual cups. Put the jello in the refrigerator to set.
Step 2: White layer
- Mix unflavored 2 tsp gelatin powder with 1 cup boiling water and stir til dissolved.
- Stir half of a 14 oz can of sweetened condensed milk into the gelatin mixture. Let it cool to room temperature.
- When the first jello layer is fully set (30 minutes) pour the room temperature white layer evenly over the first jello layer.
- Next, return the dish to the fridge to set and begin preparing the next jello layer. (Refer to step 1)
- Repeat steps 1 and 2 until you have poured all of your rainbow layers.
Pro Tips for Rainbow Jello:
- Stir together the flavored jello and gelatin before adding the hot water. This is to avoid the gelatin clumping together.
- Refrigerate each layer and make sure it is sufficiently cooled before adding the next layer.
- Cool jello mixture to room temperature before pouring it on top of a chilled layer.
- Pouring hot (or even warm) jello mixture onto a previous jello layer will result in the jello mixing together and ruining the clean, layered jello look.
- If you’re making jello in individual cups, place the cups in a larger baking dish or baking sheet so you can more easily transfer the cups back and forth from the fridge to the counter.
I use these dessert cups. We use them to make layered jello, yogurt parfaits, or to serve snacks for parties. They’re very nice and can even be hand-washed and used more than once.

This would be so easy for me to do. I will be taking this to my red hat party for the ladies.
Can’t wait. Thank you. Wonderful ideas.
My kid would be obsessed with this. Also never knew about how to get white so thank you.
It is so fun!
