A small, decorative, round or square cookie imprinter, usually made of glass, ceramic or wood. When the stamp is pressed into a ball of cookie dough, it not only flattens it, but imprints a relief design on the surface. Cookie stamps come in many designs and are available at specialty kitchenware shops.
