Carob is often used as a substitute for chocolate or cocoa powder in cakes, cookies, and candy. To substitute carob powder for cocoa, replace one part cocoa with one and one-half to two parts carob by weight. Keep in mind that carob is not as flavorful as chocolate, so it is best used in recipes that contain other strongly flavored ingredients. But because carob is naturally sweet, it isn’t usually necessary to add sugar when using it in place of unsweetened cocoa powder. Carob chips are easily substituted for chocolate chips in cookie and muffin recipes, and many people enjoy hot beverages made from carob powder as a substitute for coffee.
