Preheat the oven to 350°F. Line a loaf pan with parchment paper or greased foil. Set aside.
Peel bananas and add to a large mixing bowl. Using a sturdy whisk or fork, mash bananas until smooth. Add the coconut oil, maple syrup, sugar, flax egg and vanilla. Whisk until well incorporated.
Add oat flour, almond meal, cocoa powder, baking powder, baking soda and salt. Whisk together until just incorporated, making sure no flour patches remain. Gently fold in walnuts and chocolate chips.
Pour batter evenly into prepared loaf pan. Optional: lightly sprinkle with chopped walnuts and chocolate chips.
Bake for 65-80 minutes. (Mine took 75 minutes.) Test for doneness by sticking a toothpick into the center of the loaf. The toothpick will come out clean when the loaf is done.
Allow to cool on a cooling rack for about 1 hour. Lift out, slice and enjoy!
