Preheat your oven to 350 and line a loaf pan with parchment paper.
In a medium sized mixing bowl, stir together your dry ingredients: oat flour, cocoa powder, baking powder, baking soda, cinnamon, salt.
In a large mixing bowl, whisk together your coconut oil and sugar. Add your mashed banana and whisk again. Finally, add your eggs and vanilla and whisk.
Pour your dry ingredient into your wet ingredients and stir till all is well combined. Add your chocolate chips and gently fold them into your batter.
Pour your batter into your loaf pan. Sprinkle extra chocolate chips on top if you'd like. Bake in the oven for 45-50 minutes, or till the top is springy and a toothpick inserted comes out clean.
Let your loaf cool for about 30 minutes before removing it from your loaf pan.
Slice and devour!
Stored in an airtight container in the fridge, this bread will last about a week.
