National Chocolate Chip Cookie Day

Celebrated on 08/04/2026

Quick Fact

Chocolate chip cookies were invented by accident in 1938 when Ruth Wakefield, owner of the Toll House Inn, ran out of baker's chocolate and used a chopped semi-sweet chocolate bar instead, expecting it to melt into the dough. The resulting cookies with chunks of chocolate became an instant hit, and the rest is history.

Origins and Establishment of National Chocolate Chip Cookie Day

National Chocolate Chip Cookie Day is celebrated annually on May 15th. The exact origins of this food holiday are unclear, but it is believed to have been created by the cookie industry or a marketing campaign to promote the beloved treat. The day honors the chocolate chip cookie, which was invented in 1938 by Ruth Wakefield at the Toll House Inn in Whitman, Massachusetts. The cookie's popularity soared after Nestlé struck a deal with Wakefield, printing her recipe on their chocolate bar packaging and later creating pre-chopped chocolate chips.
