Who invented the chocolate chip cookie?
Ruth Wakefield invented the chocolate chip cookie in 1938 when she added broken chocolate pieces to dough, expecting them to melt.
She ran out of baker's chocolate and used a Nestlé semi-sweet bar instead. The chocolate chunks stayed solid instead of mixing into the dough, creating the first chocolate chip cookie.

Ruth Wakefield was a dietitian who ran the Toll House Inn in Massachusetts. Her recipe became famous after she published it in her 1938 cookbook. During World War II, soldiers shared these cookies with others, which made the recipe popular across the United States.In 1939, Wakefield sold the rights to the recipe and the Toll House name to Nestlé. She received a lifetime supply of chocolate as part of the deal. Nestlé started selling small chocolate morsels specifically for these cookies in 1941.The cookie changes color and flavor through the Maillard reaction. This is a chemical process where heat turns sugars and proteins brown. The chocolate pieces stay in shape because they have a higher melting point than the butter in the dough. Americans now eat about 7 billion chocolate chip cookies every year.
