Part 2/15:
One of the most beloved treats in America, the chocolate chip cookie, was born in 1938 when Ruth Wakefield mistakenly ran out of Baker's chocolate. Opting to chop up a semi-sweet chocolate bar instead, she created gooey pockets of chocolate within her cookie dough. The innovation not only became a classic favorite but led to a partnership with Nestle, resulting in the chocolate chip cookie as we know it today.
