Preheat the oven to 350F and grease an 8″ or 9″ loaf pan with coconut oil.
In a medium bowl, whisk together the flour, cinnamon, baking powder, and baking soda. Set aside.
In a large bowl, mash the banana until minimal or no lumps remain. Add in the coconut sugar, coconut milk, coconut oil, and vanilla extract. Whisk together.
Fold the dry ingredients (including optional shredded coconut) into the wet until just combined.
Pour the batter into the loaf pan, and top with more shredded coconut (optional).
Place the pan into the oven and bake for ~65 minutes, or until a toothpick comes out clean and the top of the banana bread is slightly browned.
Remove from the oven and allow the coconut banana bread to cool in the pan for 10 minutes before removing.
Slice and serve warm. Store any leftover slices in an airtight bag or container for up to 5 days in the fridge or up to 1 month in the freezer.
