Preheat oven to 375, and grease three mini loaf pans (5x3x2).
Combine flour, sugar, ginger, baking powder, baking soda and cinnamon in a large mixing bowl.
Mix in banana, butter and molasses until well blended, about 2 minutes on medium speed.
Stir in eggs until well combined.
Divide batter among loaf pans and bake for 30 minutes or until a toothpick comes out clean.
Cool in the pans for about 15 minutes, then continue cooling on wire racks.
When completely cool, gently spoon powdered sugar into a wire mesh strainer, and shake the strainer over the loaves to garnish.
Notes
Ginger: Look for this dried and powdered version of ginger in the spice section of your supermarket.
Bananas: You need them to be pretty ripe so that you can smoosh them easily. They don’t have to be totally smooth…a few banana lumps are just fine.
Molasses: Look for this rich dark sweet liquid in the baking aisle. We recommend either light or dark molasses. Blackstrap molasses is a little too intense for this recipe.
