Lightly spray a small muffin pan with cooking spray, peel the broken crayons and put them in the pan. Using seasonal pans are fun too, i.e. hearts around valentines. My daughter got one in a little treat bag at school last year and loved it!
Bake at 250 degrees for about 10 minutes.
Once the pan cools down a bit, put it in the fridge to cool the rest of the way- 10 or 15 minutes. After pounding the pan upside down on the floor or counter a few times they should come right out!
