The chocolate chip cookie was the accidental invention of Ruth Graves Wakefield. She and her husband owned and operated the Toll House Inn in Whitman, Massachusetts in the mid-1930s. Wakefield prepared meals and desserts. One day she was without Baker's Chocolate for a butter drop cookie recipe. She cut a Nestlé's semi-sweet chocolate bar into bits and added the bits to the dough, thinking the pieces would melt as the cookie baked. The bits did not melt completely, but they did soften. The result was called the Toll House Cookie. Nestlé printed the recipe on its packages of chocolate. Wakefield received a lifetime supply of Nestlé semi-sweet chocolate for her permission to print the recipe.
