Preheat your oven to 350°F (175°C) and line a loaf pan with parchment paper.

In a small bowl, whisk the flaxseed meal with the water and let it sit for 5-10 minutes to form a gel.

In a large bowl, combine the almond flour, oat flour, baking powder, baking soda, and Kosher salt. Whisk to combine.

In a separate bowl, whisk together the mashed bananas, the prepared flax egg, and melted coconut oil until well combined.

Pour the wet ingredients into the dry ingredients and stir gently until just combined. Fold in the vegan chocolate chips.

Transfer the batter to the prepared loaf pan and bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
