Preheat the oven: Set to 350°F (175°C). Grease a 9x5-inch loaf pan or line with parchment paper.
Mash the bananas: In a large bowl, mash bananas until smooth (small lumps are okay).
Mix wet ingredients: Add honey, eggs, applesauce, and vanilla extract. Whisk until combined.
Combine dry ingredients: In a separate bowl, mix whole wheat flour, baking soda, baking powder, cinnamon, and salt.
Combine wet and dry: Gradually add dry ingredients to wet, stirring gently. Add almond milk to loosen batter. Fold in optional add-ins.
Pour and bake: Pour batter into the loaf pan. Bake for 50-60 minutes, until a toothpick comes out clean.
Cool and serve: Cool in pan for 10 minutes, then transfer to a wire rack. Slice and enjoy!
