Preheat oven to 350 degrees.
In a blender, combine the bananas, applesauce, non-dairy milk, and vanilla. Blend until smooth.
In a large bowl, whisk the flour, baking soda, salt, cocoa powder, and coconut sugar together well.
Add in the banana mixture and stir to combine. Do not overmix.
Pour into a standard-size, non-stick loaf pan.
Bake for 45 minutes and insert a toothpick in the center to make sure the bread is done. If the toothpick comes out clean, remove from the oven and let cool a bit before serving. If the bread is not done, continue baking and checking every 5 minutes or so.
