Preheat oven to 350 degrees and grease a regular 9"x5” loaf pan with cooking spray or coconut oil
In a large bowl, combine the wet ingredients: banana, eggs, applesauce, coconut oil, maple syrup and vanilla.
Next, add in all the dry ingredients in the same bowl on top of the wet ingredients: brown rice flour, almond flour, salt, baking soda, and cinnamon (and any of the optional dry ingredients you want to add).
Stir completely to combine until the only lumps left are from the bananas.
Pour batter into loaf pan and bake for about 45-50 minutes until golden brown on top and cooked through.
Remove from oven and let cool in the pan for a few minutes before removing from pan to cool completely.
Store in an airtight container in the fridge for up to a week or freeze for up to a month.
