Did you celebrate National Chocolate Chip Day? It happened last month, May 15 to be exact!
According to National Day Calendar, Ruth Graves Wakefield of Whitman, Massachusetts, was probably curious about what a little bit of chocolate would be like added to her cookies. In 1937, while working at the Toll House Inn, Wakefield added cut-up chunks of a semi-sweet Nestle chocolate bar to her cookie recipe.
The cookies were a huge success!
