Preheat oven to 375F and line an 8x4 loaf pan*** with parchment paper, set aside.
In a small bowl, combine coconut flour, cinnamon, nutmeg, baking powder, baking soda, and salt until fully combined and no more clumps of flour are present. Set aside.
In a medium bowl (or large measuring cup) mash your ripe bananas until no more lumps are present. (I used my immersion blender to puree.)
Add cashew butter, maple syrup, and vanilla extract to medium bowl with banana and whisk until combined. (If you keep your nut butter in the fridge, you may need to warm in the microwave slightly.) Add 2 large eggs and whisk until combined with rest of wet ingredients.
Add coconut flour mixture to medium bowl of wet ingredients. Using rubber spatula, gently stir until combined.
Pour batter into prepared baking pan and bake for 22-27 minutes (mine took 25).
Let bread cool in pan for 15 minutes before slicing. Store banana bread in fridge up to 3 days fresh, or freezer up to 1 month.
Notes
*There are no substitutions for coconut flour, as it's baking properties are so unique. I do not recommend using other flours to substitute.**Any natural nut or seed butter should work***9x5 pan will work, your bread may just be a little thinnerRecipe slightly adapted from Ambitious Kitchen
