Sometime in 1930: The chocolate chip cookie is accidentally invented by Ruth Wakefield of Whitman, Massachusetts. “Wakefield is said to have been making chocolate cookies and on running out of regular baker’s chocolate, substituted broken pieces of semi-sweet chocolate from Nestlé thinking that they would melt and mix into the batter. They did not and the chocolate chip cookie was born.”
