Prep the baking pan but spray with non-stick cooking spray and then lightly wipe off any excess.
Pour the mixture into the prepared pan.
Then, place in the refrigerator until the Jello sets, at least 3-4 hours. I usually just let it set overnight.
You can use a sharp knife to cut the Jello into squares or rectangles. Or you can use cookie cutters to create shapes. Use a spatula or your clean hands to remove Jello Jigglers from the pan.
Notes
The metal pan can be 9×9 inches or 8×8 inches. The smaller size will make slightly thicker Jello Jigglers.
Be sure to use boiling water as that helps the jello solidify.
Leftover Jello Jigglers can be stored in the refrigerator for up to five days.
Be sure to grease your pan with non-stick cooking spray before adding the jello to the pan to avoid it sticking to the pan.
Refrigerate for 3 hours or until jello is solid, I usually just let it chill overnight.
