Preheat oven to 350.
LIghtly grease a 9-inch loaf pan with cooking spray and sprinkle with flour; set aside.
In a small mixing bowl combine flours, baking soda and salt; whisk until combined and set aside.
Mash bananas in a large mixing bowl; add sugar and, using a large spoon, mix until combined.
Stir in beaten eggs and continue to mix until well incorporated.
Stir in coconut oil, stirring until incorporated.
Add flour mixture to the banana mixture and mix just until combined.
Transfer batter to previously prepared pan.
Bake for 45 to 50 minutes, or until a toothpick inserted in the center comes out clean.
Remove from oven and cool completely on a rack.
Remove bread from the pan.
Using a bread knife, slice the banana bread and serve.
Optional: Top slices with a sliver of butter and a drizzle of honey - it's heavenly!
