Preheat oven to 350 degrees F and grease a 9-inch by 5-inch loaf pan with cooking spray or line it with parchment paper.
In a large bowl, mix together mashed bananas, coconut oil, eggs and honey.
In a separate bowl, whisk together oats, flour, baking powder, baking soda, and salt.
Stir dry ingredients into the wet ingredients. Mix well to incorporate, then add in chocolate chips, nuts, or raisins, if desired.
Pour the batter into the prepared pan. Bake for 40-50 minutes or until the toothpick inserted comes out clean.
Let cool completely. Cut into slices and enjoy.
