Add Jello mix into a large bowl, and pour in 2 cups of boiling water. Stir for about 2-3 minutes, ensuring the mix is fully dissolved.
Lightly spray your chosen mold or pan with cooking spray, and gently wipe with paper towels to ensure easy removal of the finished Jigglers.
Pour the dissolved gelatin mixture into the mold or pan.
If needed, use toothpicks to poke any visible bubbles on the surface for a smooth finish.
Refrigerate for at least three hours or until firm enough to hold their shape.
Finally, use cookie cutters or a knife to cut the Jello Jigglers into your desired shapes. You can get creative with various designs that suit the occasion or theme of your gathering. Be sure to loosen the edges with a knife or by dipping the mold bottom in warm water for a few seconds before removing the Jigglers.
