Chocolate chip cookies are a popular type of cookie that originated in the United States. They are made from a dough that typically includes ingredients like flour, sugar, butter, eggs, and vanilla, with chocolate chips added for sweetness and flavor. The cookies are usually baked until they are golden brown on the edges while remaining soft in the center. These cookies can be enjoyed warm or at room temperature and are often served as a dessert or snack. They are versatile, allowing for variations such as adding nuts or using different types of chocolate like dark or white chocolate.
