I've featured some pretty awesome polymer food jewelry before (see links below).  They are so realistic, you almost want to take a bite!  Nothing is more scrumptious than the ones which mimic baked goods. 

Mo Tipton's polymer clay heart cookie charm tutorial shows how it is done.   It is a meticulous how- to as she even demonstrates the 3 different ways to get the cookie shape.   You'll have to hop over and find out what she uses to make the clay rough so it looks like a real cookie once it is baked.

Mo says,  "I combine my love of miniatures with my training as a pastry chef and a graphic designer to create detailed, realistic foods in 1/12 and 1/6 scale."  See more of her designs on her website called The Mouse Market.

Also delicious looking is the chocolate chip cookie pendant tutorial by Madizzio (Madeleine) on Deviantart.
