Step 1

Preheat the oven to 350 degrees. Grease a 12-count muffin tin.

Step 2

In a large bowl, combine the bananas, cinnamon, vanilla, oil, egg, and brown sugar. Mix well.

Step 3

Add the flour, protein powder, baking powder, baking soda, and salt. Stir the ingredients until just combined.

Step 4

Add the milk and mix until everything is combined. Fold in the chocolate chips.

Step 5

Pour the batter evenly into each spot in the muffin tin, filling almost completely. Bake for approximately 20 minutes, or until muffins are golden brown on top and a knife pulls out clean. Let cool for a few minutes in the pan, then remove from the pan and allow to finish cooling. Enjoy.
