Chocolate cookies are a popular baked treat made primarily from flour, sugar, butter, and cocoa powder. They often include chocolate chips or chunks, which melt during baking, creating a rich, gooey texture. These cookies can be soft and chewy or crisp, depending on the recipe and baking time. Many variations exist, including double chocolate cookies, which use both cocoa powder and chocolate chips, and gluten-free chocolate cookies, made with alternative flours. Chocolate cookies are enjoyed worldwide and are often served as a dessert or snack, appealing to both children and adults alike.
