Big Thanks again to Catholic Icing for the recipe to this great teaching tool! When me and the girls made these, they weren't very pretty so I didn't get any pictures. Plus, they were so yummy that we inhaled them down fast! So anyway, go over to Catholic Icing to check out what they look like and how to make them.
Basically, what you do is dip a marshmallow in melted butter and then cinnamon and sugar. And then you wrap it in a crescent roll. When you bake it, the marshmallow melts, leaving the roll empty (just like Christ's tomb!)
