Preheat oven to 350 degrees Fahrenheit. Spray a 9 x 5-inch non-stick loaf pan with baking spray, or grease with butter.
In a bowl, whisk together the flour, baking soda, baking powder, salt, ginger, cinnamon, clove, and nutmeg.
In the bowl of your mixer, add the mashed bananas, eggs, oil, molasses and sugar. Mix on low to combine.
Add the flour mixture to the wet mixture, a little at a time, mixing just enough to incorporate the flour without over-mixing.
Pour batter into the pan and bake for 45 to 50 minutes, or until a toothpick inserted in the center of the loaf comes out clean.
Remove from the oven and allow the ginger banana bread to cool for 10 minutes in the pan before removing and placing loaf on a wire rack.
While loaf is cooling, prepare the glaze. Mix together the powdered sugar, vanilla, spices, and milk. Whisk until smooth, and the correct consistency for glazing. If too thick, add more milk a few drops at a time. If too thin, add more powdered sugar a little at a time.
When loaf is fully cooled, drizzle glaze across the entire loaf, allowing it to drip over the sides.
