Place the gummy bear mold on a large baking sheet. This will make it easier to transfer after the molds are filled.
Add the Jel dessert, gelatin, and water to a small saucepan. Dissolve crystals over low heat until completely dissolved and slightly warmed for about 3 minutes.
Remove the saucepan from the heat and, working quickly, use the dropper from the gummy bear kit to fill cavities. If you don’t have a dropper, you can also very carefully pour the mixture over the gummy bear molds, and wipe off any excess spill-over with a butter knife.
Transfer to the refrigerator to set for least 1-2 hours for best texture. Pop out of the molds and enjoy.
Store gummy bears in the refrigerator in an airtight container.
