Chocolate-chip Cookies

A chocolate chip cookie is a drop cookie that is distinguished by the presence of chocolate chips or chocolate morsels. Ruth Graves Wakefield invented chocolate chip cookies in the United States about 1938, when she broke up a Nestlé semi-sweet chocolate bar and put the chopped chocolate to a cookie recipe.

In general, the recipe begins with a dough made of flour, butter, brown and white sugar, semi-sweet chocolate chips, eggs, and vanilla extract. Other varieties of chocolate, as well as extra ingredients such as nuts or oatmeal, may be used in variations of the recipe. Vegan versions are also available, with required ingredient replacements such as vegan chocolate chips, vegan margarine, and egg substitutes. A chocolate chocolate chip cookie is made using a dough that has been flavored with chocolate or cocoa powder before adding chocolate chips. Depending on the combination of dough and chocolate kinds, these variations of the recipe are also known as 'double' or 'triple' chocolate chip cookies.
