Chocolate chip cookie
cookie including pieces of chocolate
A chocolate chip cookie is a drop cookie that contains pieces of chocolate mixed into the dough before baking. Texture and appearance vary with ingredients and preparation, ranging from moist, chewy cookies to ones that are crispy.
Chocolate chip cookies are closely associated with the United States, where they are the most popular cookie. Their invention is generally credited to Massachusetts chef and hotelier Ruth Graves Wakefield in the 1930s, although versions existed that preceded hers. Over the 20th century they gained popularity through their association with the Swiss company Nestlé, their distribution to American troops in World War II, and the development of new versions in the 1970s and 1980s by manufacturers such as Famous Amos and Mrs. Fields.
Chocolate chip cookies are made from eggs, white and brown sugar, flour, a leavener, fat, vanilla, and small pieces of chocolate. The starch in the flour is responsible for the cookie's ability to set, while brown sugar and the practice of adding eggs one at a time contribute to chewiness. Nuts and other inclusions are sometimes added, and spin-offs have been developed including chocolate chip cookie dough ice cream and an ice cream sandwich.
Ingredients
Chocolate chip cookies are commonly made with white sugar, brown sugar, flour, salt, eggs, a leavening agent such as baking soda, a fat, typically butter or shortening, vanilla extract, and chocolate pieces.
