Regarding the clay cookie molds YOU DO NOT BAKE THE COOKIE IN THEM!!!! You have to make a special dough recipe then you press the dough in the very lightly oiled (a spray of PAM works best) and floured mold. You then give a swift bang of the mold on a wooden cutting board and the preformed cookie should come right out and you place it on a cookie sheet and bake as normal. Here is a great guide on how to use them:
