Sometimes an unexpected cake ingredient is used to replace another ingredient to make the cake healthier or lighter in fat, calories or cholesterol. And that's the deal with tofu. This soybean curd is a staple in vegetarian and Asian diets that can also be used as an able replacement for eggs and oil in many cake recipes. Just don't try to eat a slice with chopsticks.
