Preheat the oven to 350 degrees. Thoroughly grease a 9 x 5 inch loaf pan.
In a large mixing bowl, whisk together the flour, salt, soda, ginger, cinnamon, nutmeg, and cloves. Set aside.
In another bowl, whisk together the butter, sugar, and molasses until well combined. Whisk in the eggs, one at a time, until well combined. Stir in the milk and smashed bananas.
Add the flour mixture to the banana mixture and stir until no white remains. Pour into the prepared pan and bake until a toothpick inserted in the center comes out clean, or 45-55 minutes.
