You can change things in this recipe according to taste. You might like to add nuts or a little clove seasoning. I have made this with one banana and the water made up the difference in the right consistency. More bananas use a little less water. This comes out quite moist. You can pour this into a square cake pan and serve it without frosting as a snack too, but watch the timing. It might need less baking time.
