Preheat your oven to 350°F (175°C) and grease a loaf pan.
In a large bowl, mash the ripe bananas until smooth.
Add almond milk, vegetable oil, brown sugar, and vanilla extract to the mashed bananas.
Mix until all wet ingredients are combined.
In another bowl, whisk together the flour, baking soda, and salt.
Gradually add the dry ingredients to the wet mixture.
Stir until just combined; do not overmix.
Fold in walnuts or chocolate chips if desired.
Pour the batter into the prepared loaf pan.
Bake for 50-60 minutes or until a toothpick inserted comes out clean.
