I searched high and low for a way to make a cake from a boxed mix so other preschool moms could easily use the recipe for class parties (my daughter has food allergies). The challenge - when using egg substitutes, the box mixes just don't rise well and tend to crumble apart. These actually hold their shape, have a nice flavor (very sweet!), and are so easy to make. If you don't like the flavor of banana, you can substitute 1/3rd cup of applesauce instead. They do better at holding together if they are refrigerated overnight before serving.
