The story of the chocolate chip is inextricably linked to the invention of the chocolate chip cookie. In the 1930s, Ruth Wakefield, co-owner of the Toll House Inn in Whitman, Massachusetts, created what would become the first chocolate chip cookie. She chopped a Nestlé semi-sweet chocolate bar into small bits and added them to cookie dough, expecting them to melt. Instead, they held their shape—resulting in a new, delightful texture.
Nestlé saw an opportunity and struck a deal with Wakefield: in exchange for printing her recipe on their packaging, she would receive a lifetime supply of chocolate. Shortly afterward, Nestlé began selling chocolate in the form of small chips or “morsels,” and the chocolate chip was officially born.
Today, chocolate chips come in a wide variety of forms: semi-sweet, milk, dark, white and even specialty flavors like peanut butter, butterscotch and mint. They’re a staple in pantries and have become a crucial ingredient in many dessert recipes.
Why Celebrate Chocolate Chip Day?
Chocolate Chip Day is about more than just indulgence. It’s a chance to appreciate how a small innovation—cutting chocolate into small, convenient pieces—revolutionized baking. Before chips, adding chocolate to recipes meant chopping up bars, which was time-consuming and inconsistent.
The invention of the chocolate chip made baking easier, more consistent and more versatile. Chocolate chips melt just enough to create pockets of sweetness without losing their shape, which is part of what makes cookies gooey and brownies rich. Their portability and ease of use have made them popular not only in baking but also in snacks and breakfast foods.
