In a large bowl, mix together the flour, brown sugar, baking soda, baking powder, salt, and cinnamon.
Combine the bananas, aquafaba, applesauce, vanilla, and oil in your blender.
Pour the blender mixture into the dry ingredients mixture, then stir in the apple pieces.
Use a spoon or an ice cream scoop to scoop the batter into a lined muffin tin. You want each cup about ¾ full. Bake for 18 to 22 minutes or until a toothpick inserted into the center comes out clean. Cool for 10 to 15 minutes before serving.

Notes
Most of the sweetness in this recipe comes from the bananas, but there is a little bit of brown sugar to up the sweetness. I have cut the refined sugar down as much as possible already. If you absolutely do not do refined sugars, I recommend adding 3 to 4 pitted dates and blending them with the wet ingredients.We make these muffins often and love experimenting with different mix-ins! Instead of the chopped apple, we've really liked these with 1 to 1 ½ cups of blueberries, 1 ½ cups frozen cherries (not thawed), or 1 cup sliced strawberries. My son, loves that he gets to choose each week's muffin addition!
