The best tips are this:
The lamb cake mold takes ONE cake mix, spread shortening throughout both sides of mold, then flour thoroughly. Pour the cake mix into the bottom half, place toothpicks in appropriate places, only to support the head. Place the top of the mold onto the bottom, and bake (the cake mix will rise appropriately filling both halves). I have yet to find info on baking instructions, but I believe it is as the recipe on the box states, and about 5 more minutes. Not sure though, I will have to get back to you on that!
