Preheat oven to 350°F. Line a 12-cup muffin tin with paper liners.
In a medium bowl, whisk together the almond flour, baking powder and salt.
In a large bowl, mash the bananas. Then mix in the almond butter, eggs, maple syrup and vanilla until combined.
Add the dry ingredients to the wet ingredients and gently stir just until combined. Fold in chocolate chips or nuts if using.
Divide batter evenly among the muffin cups.
Bake for 18-22 minutes until a toothpick inserted in the center comes out clean.
Allow muffins to cool for 5 minutes before removing from tin. Enjoy!
