Chocolate chips are small pieces or chunks of chocolate, typically used as a dessert topping or ingredient in baking. They are made by melting down chocolate and then forming it into small balls before cooling and hardening them. Chocolate chips can be found in various sizes and flavors, with popular varieties including milk chocolate, dark chocolate, and white chocolate. In baking, they are often used to add texture, sweetness, and a rich chocolate flavor to cookies, cakes, brownies, and other treats.
