Preheat the oven to 375°F. Line a 12-cup muffin tin with paper or silicone liners, or spray with cooking spray.
In a large bowl, combine the flour, oats, brown sugar, baking powder, baking soda, salt, and protein powder if you're adding it.
In another bowl whisk together the eggs, oil, milk, and mashed bananas.
Pour the wet ingredients into the dry and stir until just combined. Fold in the chocolate chips if you're adding them
Divide the batter between the muffin cups - they will be quite full. Bake for 15 to 16 minutes, or until a wooden pick inserted in the center of a muffin comes out clean.
