Red Jello (raspberry, cherry, strawberry)
Orange Jello (orange, peach)
Yellow Jello (lemon, pineapple)
Green Jello (green apple, lime)

How to Make Layered Jello in a Cup

Step 1: Jello layer

Mix 1 teaspoon 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 teaspoon 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 in a Cup

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.
Do not pour hot (or even warm) jello mixture onto a previous jello layer. It 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.

Layered Jello FAQ

Do you Cover Jello after making it?

Cover Jello only after it's cooled down.

After the jello has been set properly, it is a good idea to cover it with plastic wrap so that it doesn't pick up other smells or flavors from the fridge.

Is it Hard to Make Layered Rainbow Jello?

Making layered jello is easy, but it is time-consuming! Each layer requires about 30 minutes to set before you can add a new layer, plus you need to let each new batch of jello cool a little before pouring it on the previous layer.

The reactions I see on the faces of my friends and family always make it worth my time.

What kind of cups do you use for Jello in a cup?

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.
