Sift the flour, cocoa powder, baking soda, and salt into a medium bowl. Set aside.
Mash the bananas. Add the eggs, coconut milk, coconut oil, and maple syrup. I like to mash the bananas in my blender, then I add the other ingredients and mix them in there. I transfer these wet ingredients to a large bowl.
Add the dry ingredients to the wet ingredients, and stir to combine. Stir in the chocolate chips.
Transfer the batter to a standard loaf pan or two mini loaf pans, filling the pan(s) 3/4 of the way to the top. Bake the bread for about 50 minutes in the full-sized loaf pan or 40 minutes in the mini loaf pans. Either way, the bread is done when a toothpick inserted in the center comes out clean.
