Preheat oven to 375 degrees. Spray a 9 x 13 loaf pan with coconut spray.
In a bowl, mix dry ingredients together. Set aside.
In a separate bowl, mash bananas until relatively puréed. Add remaining ingredients up to chips and stir until evenly combined.
Add dry ingredients to wet ingredients (3/4 cup of the coconut milk) in two batches. Fold until combined. Mixture should be thick but still able to be poured.
Mix in the chips and fold lightly.
Pour into a prepared bread pan and bake for 30 minutes, or until a toothpick inserted in the center comes out clean.
While baking, add the chocolate chunk chips and 1/4 cup of coconut milk to a small bowl and melt over a pot of water until creamy. Top the bread loaf after it has cooled from baking.
Serve and enjoy!
