Preheat the oven to 350ºF. Brush a 9x5 loaf pan with vegetable oil and dust with flour.
In a large bowl, mash the banana. Add the brown sugar, molasses, non dairy milk, vegetable oil and vanilla. Whisk everything together.
4 medium bananas, ¼ cup brown sugar, ¼ cup molasses, ¼ cup vegetable oil, ¼ cup non dairy milk, 2 tsp vanilla extract
Place a sieve over the bowl and sift in the flour, baking soda, salt and spices.
2 cup all purpose flour, 1 tsp baking soda, ½ tsp salt, ½ tsp ground ginger, ½ tsp ground cinnamon, ¼ tsp ground nutmeg, ⅛ tsp ground cloves
Mix the wet and dry ingredients together using a spatula or a wooden spoon until there are no traces of flour. Do not over mix.
Pour the batter into the oiled and floured loaf pan. Use a spatula to spread the batter evenly in the pan.
Loosely cover the loaf pan with aluminum foil and bake for 45mins. Remove the foil and bake for another 15-20mins. Stick a toothpick in the middle of the loaf, and if it comes out with wet batter, baking for another 5mins.
To make the glaze, whisk all the ingredients together. Start with 1 tbsp of water, and gradually add ½ tbsp of water at a time until the desired consistency is reached.
1 cup icing sugar, 1½-2 tbsp water or non dairy milk, ½ tsp vanilla extract
Transfer the baked loaf onto a cooling rack to cool completely before drizzling on the glaze. Allow the glaze to harden before storing.
