A cookie cutter in North American English, also known as a biscuit cutter outside North America, is a tool to cut out cookie/biscuit dough in a particular shape.
They are often used for seasonal occasions when well-known decorative shapes are desired, or for large batches of cookies where simplicity and uniformity are required. Cookie cutters can also be used for shaping, molding, forming and cutting numerous other types of foods, including meat patties, flapjacks, sandwiches and decorative embellishments for platters (for example, fancy-cut fruit).
