I follow this recipe to a "T" but I also learned a trick from my boyfriend that his mother used to do (he just observed). She would take a ripe banana and mash it up real good (a blender or food processor really helps!) and she would mix it in with the rest while it was on the stove. You just have to be a little more careful making sure it doesn't stick. It bakes pretty much the same but it makes it so much more moist on the inside and adds to the already enticing flavor with a hint of banana!
