It is possible to make a cake from a boxed mix without eggs. Some popular substitutions for the eggs include applesauce, bananas, pudding, yogurt and even tofu.
Chefs often substitute the eggs for a boxed cake mix with applesauce, bananas or pudding to make the cake more moist than using eggs normally allows. Vegans use soy yogurt, silken tofu, flax seeds or a commercial egg substitute. Substitute 1/3 cup applesauce, 1/2 cup pureed bananas, 1/4 cup soy yogurt or 1 tablespoon flax seeds for each egg in the recipe. Commercial egg substitutes use conversions that are printed on the carton.
