Heat oven to 350°F (180°C) and line a 20 cm loaf pan with parchment paper or grease with oil.

In a large bowl, mash the bananas then combine with cottage cheese, egg, maple syrup, ground cinnamon, vanilla extract, and a pinch of salt. Stir well until smooth.

Add oat flour, almond flour, and baking powder to the wet mixture. Stir the ingredients together.

Adjust the batter consistency with more flour if too liquid, or a splash of milk if too dry, depending on the banana size.

Transfer the batter to the prepared pan, then bake in the oven for about 30 minutes. The banana bread is ready when a toothpick inserted into the center comes out clean.
