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.
