In 1930, Ruth Wakefield was mixing a batch of cookies for her roadside inn guests when she ran out of baker’s chocolate. She substituted broken pieces of Nestle’s semi-sweet chocolate, expecting it to melt and absorb into the dough. However, this process failed. When she removed the pan from the oven, Wakefield realized that she had accidentally invented “chocolate chip cookies.”
As the cookies grew in popularity and Nestle’s chocolate sales spiked, Wakefield and the company came to the agreement of her receiving a lifetime supply of chocolate in exchange for the recipe being printed on the chocolate packaging. Due to her fortunate “mistake”, the chocolate chip cookie became the most popular variety of cookie in America, a distinction it still holds to this day.
