Grease a 9x5x4 inch loaf pan (or 9-inch cake pan) or layer with parchment paper. Set aside.
In a medium sized bowl, add the dry ingredients; whole wheat flour, sugar, baking powder, baking soda, cinnamon powder, flaxseed powder and salt.
In another large mixing bowl, peel and mash bananas well using a potato masher. Try and make as smooth of a mixture as possible.
To this add ¼ cup almond milk, vanilla essence and oil.
Mix well with a spoon.
Add the dry ingredients and using a spatula, gently fold to make a homogenous mixture, with no dry portions visible. DO NOT OVERMIX!
If you find the batter a bit thick, feel free to add more liquid to make a thick pancake like flowy batter; about 2 tbsp or more as needed.
Bake in preheated oven for 50 to 60 minutes in loaf pan and 30 minutes for 9-inch round pan or until a toothpick inserted in center of cake comes out clean. Start checking at 50 minutes for the loaf pan. My loaf banana bread came out perfect at 55 minutes. Each oven is different and may take more or less time to bake.
