(CNN) - They melt in your mouth, and it's impossible to eat just one.

Monday is National Chocolate Chip Day.

Ruth Graves Wakefield, of Massachusetts, is responsible for their creation. In the 1930s, she added chunks of chocolate bar to a cookie recipe while working at the Toll House Inn.

The cookies became famous and she made a deal with the Nestle company, whose chocolate she had used, to have the recipe printed on their packages. In return, Nestle began selling the tiny pieces of chocolate separately from its bars.

It's OK to eat chocolate chip cookies in celebration, but they get their own special day Aug. 4.
