Preheat the oven to 350℉.
Add the oat flour, cinnamon, baking powder, and baking soda to a large mixing bowl.
Mix all ingredients thoroughly to combine.
Make a well in the center of the bowl, then add the mashed bananas, nut milk, peanut butter, applesauce, and pure maple syrup.
MIx the wet ingredients to combine, then slowly mix the wet ingredients into the dry to form a smooth muffin batter.
Gently fold in the fresh blueberries.
Grease or line six cavities of a muffin pan.
Distribute the batter evenly between the six cavities.
Top each muffin with a few more fresh blueberries and a bit of coconut sugar.
Pop the muffins in the oven to bake for about 30 minutes, or until a toothpick inserted comes out clean.
Dig in and enjoy!
