A chocolate chip cookie is a drop cookie that features chocolate chips or chocolate morsels as its distinguishing ingredient. Chocolate chip cookies are claimed to have originated in the United States in 1938, when Ruth Graves Wakefield chopped up a Nestlé semi-sweet chocolate bar and added the chopped chocolate to a cookie recipe; however, historical recipes for grated or chopped chocolate cookies exist prior to 1938 by various other authors.

A cookie or biscuit is a baked snack or dessert that is typically small, flat, and sweet. It usually contains flour, sugar, egg, and some type of oil, fat, or butter. It may include other ingredients such as raisins, oats, chocolate chips, or nuts.
