Wakefield stated that she deliberately invented the cookie. She said, "We had been serving a thin butterscotch nut cookie with ice cream. Everybody seemed to love it, but I was trying to give them something different. So I came up with Toll House cookie."
Wakefield wrote a cookbook, Toll House Tried and True Recipes, that went through 39 printings starting in 1930. The 1938 edition of the cookbook was the first to include the recipe for a chocolate chip cookie, the "Toll House Chocolate Crunch Cookie".
Wakefield gave Nestlé the right to use her cookie recipe and the Toll House name for one dollar. Nestlé began marketing chocolate chips to be used especially for cookies.
Wakefield died following a long illness in Jordan Hospital in Plymouth, Massachusetts.
