Preheat your oven to 350 degrees. Grease a 9x5 loaf pan, you can also add parchment paper for easier clean up and release of the bread.
In a medium sized bowl, mix together your dry ingredients: flours, baking soda, salt, cinnamon)
In a smaller bowl, whisk the eggs, and add in wet ingredients: bananas, coconut oil, maple syrup.
Fold wet ingredients into dry and mix with a spoon until all the dry pockets are gone. Now add in chocolate chips and walnuts (if using). Batter will be thick.
Spoon batter into your loaf pan. Even out the top with a spatula.
Place inside the oven and bake for 50-55 minutes, or until top is browned and a toothpick inserted in the middle comes out clean.
Remove from oven and let sit to cool for at least 10 minutes before removing from pan. If not using parchment paper, run a knife along the sides before attempting to remove bread from the pan.
