Banana bread is a favorite everywhere apparently! So if you have some old ripe banana's and a rice cooker you are on your way to a great treat. This recipe was adapted from one I saw in Japan. Asian banana's are much sweeter and smaller than the commercial ones found in North America or Europe so the sugar has been turned down in this recipe. If you like yours a bit sweeter substitute brown sugar for white sugar. Your banana's need to be very soft to touch, with black skins or very spotted to make this taste the best. If you do not have access to baking soda you may omit or substitute with 1/2 teaspoon more baking powder. Powdered milk is ok for this recipe if fresh milk is not available.
