We love using Wiltons chocolate melts to make forms for our cupcakes. I use my crockpot to melt the chocolate and have the kids use spoons to fill a mold. Tap the mold so the chocolate sets then place in the freezer. After a few minutes they are ready to use and decorate. These chocolate bat molds for Halloween came from Michaels and it was a hit with the kids.
Here is a blog mystorminateacup.blogspot.com that gives more info on this fabulous idea. The best part is they are gluten free and the chocolate seems to last forever. I don't believe I saw an expiration date on the package. I may have to add a bag to my earthquake preparedness supplies.
