Gather the ingredients.
Preheat the oven to 350 F. Grease a 9 x 5-inch loaf pan or spray with cooking spray .
Place 4 ripe bananas (peeled) in a large mixing bowl and mash them with a fork. Add ⅓ cup coconut oil and ¾ cup sugar to the bananas, and beat with a fork or an electric mixer until smooth.
Beat in 2 large eggs and 1 teaspoon vanilla extract .
In a medium bowl, whisk together 1 ¾ cups all purpose-flour , 1 teaspoon baking soda , 1 teaspoon ground cinnamon , and ½ teaspoon salt .
Gradually add the flour mixture to the banana mixture, using a rubber spatula or fork (or on low speed with the mixer) just until well incorporated. Do not overmix, which will yield a tough banana bread.
Stir in ½ cup dark chocolate chips, if using .
Scrape the coconut banana bread batter into the prepared loaf pan.
Bake for about 55 minutes until a skewer or a sharp knife inserted in the center comes out clean. Cool in the pan on a wire rack for 10 minutes, then turn out the bread and finish cooling upright on the wire rack. Slice and enjoy.
