In 1939, Wakefield sold Nestlé the rights to reproduce her recipe on its packages (supposedly for only $1) and was hired to consult on recipes for the company, which was said to have provided her free chocolate for life.

This was apparently before anyone made tiny little chocolate chips – So, Nestlé began pre-scoring its chocolate bars for easy baking, then introduced Nestlé Toll House Real Semi-Sweet Chocolate Morsels which became known as chocolate chips. (It was updated at some point to account for the availability of pre-sifted flour and other modern ingredients.)

You can find the current recipe printed on chocolate chip bags here.

Side note, respect for Overlooked! Their tagline says “Since 1851, obituaries in The New York Times have been dominated by white men. With Overlooked, we’re adding the stories of remarkable women.” Love this.
