After creating the rainbow gelatin cups, there was quite a bit of leftover gelatin. Not wanting to waste a single bit, it was a great opportunity to experiment with stained-glass gelatin.

If you need a colorful dessert for a unicorn party, baby shower, bridal shower, or any happy event, these layered cubes are a fun choice.

Of course, you do not need to start with the rainbow gelatin cups in order to make stained-glass gelatin. These tasty layered rainbow jelly cubes are excellent to make on purpose.

These bites are loaded with flavor, a fun texture, and look impressive to all the lucky guests who get to eat them!

Recipe Notes and FAQ

Why is my gelatin watery?

Watery gelatin usually results from covering the mixture before it has cooled completely and set. Covering the gelatin allows liquid from condensation to drip down into the mix, causing it to have too much water to set properly.

Should you grease a gelatin mold?

This recipe uses a simple glass dish, so no greasing is required. For molds that have edges and other fancy contours, spray the mold with a non-stick spray to keep it from getting stuck in the crevices.

How long does gelatin last?

Gelatin will stay fresh for 7 to 10 days when covered and refrigerated.

Does boxed gelatin go bad?

Unopened dry gelatin mix has an indefinite shelf life when stored at room temperature. However, if the package has been opened, the mix will only last for about 3 months. Check the box for a “best buy” date and try to use it by then for best results.
