Place the gummy bear or worm mold on a large baking sheet. This will make it easier to transfer after the molds are filled. Lightly oil the inside of each cavity of the mold.
Add the packet of sugar free flavored gelatin, unflavored gelatin, and cold water to a small microwavable bowl. Stir all ingredients together and let sit on the counter for 2-5 minutes to bloom.
After the gelatin has bloomed, place the bowl in the microwave on high for 30 seconds. Take out and stir. Place the bowl back in the microwave for another 30 seconds. Remove and stir making sure the mixture has fully liquified and all the sugar crystals have dissolved.
Moving along swiftly, use a small candy dropper to fill cavities or pour very carefully from spouted measuring cup. Wipe off any excess spill-over a the mold with a butter knife or lint free cloth.
Carefully transfer to the tray to the refrigerator to set for at least 1-2 hours for best texture. Remove tray from the fridge and pop out of the worms individually from the mold and enjoy.
Store gummy bears countertop or in the refrigerator in an airtight container.
