Step 1

Preheat the oven to 350°F. Line a loaf pan with parchment paper.

Step 2

In a large bowl, mash the bananas thoroughly using a fork.

Step 3

Add in the nut butter, baking powder, and apple cider vinegar, espresso powder, and cinnamon. Stir until smooth.

Step 4

Stir in the oat flour, almond flour, and ground flaxseed until combined.

Step 5

Spread the mixture into the lined loaf pan. Cut the remaining banana in half lengthwise and place the slices on top.

Step 6

Bake for 55-60 minutes or until the top is lightly brown and a toothpick inserted into the center of the loaf comes out clean. Remove from the oven and allow to cool for at least 15 minutes. Store leftovers in the fridge for up to a week. Enjoy!
