Preheat the oven to 350 degrees and prepare a lined or greased muffin tin.
In a bowl, mash bananas until smooth. Stir in egg, honey, and coconut oil until combined. (You can also use a stand mixer with your whisk attachment)
Add in oat flour, protein powder, baking powder, baking soda, cinnamon and ginger. Stir until combined. Fold in chocolate chips if using.
Pour the muffin batter into muffin cups, filling 3/4 of the way. Do not overfill!
Bake the muffins for 15 minutes or until the tops are golden brown and a toothpick comes out clean when inserted in the center of the muffin.
Allow the muffins to cool for 5 minutes before removing from the muffin tin.

Notes
Substitutions for this Healthy Banana Protein Muffins Recipe:
To make vegan: replace 1 egg white with 1 flax egg. Sub honey with maple syrup, use vegan protein powder.
Oil: You can use extra virgin olive oil, avocado oil or melted butter in place of coconut oil.
Protein Powders - This is my favorite vanilla protein powder, but you can also use whey protein powder or vegan protein powder to make these protein muffins. I would not use unflavored protein powder in this recipe.
Bananas - You can sub pumpkin, applesauce, or cooked, mashed sweet potatoes for the bananas with a 1:1 ratio.
Chocolate Chips - These muffins are great with or without chocolate chips. Feel free to substitute based on your preference.
