This recipe uses plenty of ripe bananas to make a moist, mildly sweet banana cake. Mash the bananas with a fork, then mix in brown sugar, melted butter, and eggs in that order. Sift in the cake flour and baking powder and mix gently with a rubber spatula. Pour the batter into a loaf pan, and for the finishing touch, top with bananas cut in half lengthwise and bake. This simple and gentle baked good is perfect for a home café experience.
