Ruth Wakefield initially expected the chocolate pieces to melt and blend into the dough, but they didn't, resulting in the distinct chocolate chip cookie.

Ways to celebrate

The chocolate chip as a distinct product didn't exist until a year after the cookie itself — Nestlé had to invent a whole new manufacturing shape, the teardrop "morsel," just to keep up with demand for Ruth Wakefield's recipe.

Snack on some, plain

Celebrate by:

  • Eating chocolate chips straight out of the bag, no baking required.
  • Comparing chip sizes and brands, since not all "chips" are actually the same shape.
