In a large bowl, add the mashed bananas, eggs, egg whites, vanilla, and milk. Whisk until fully combined.
Whisk in the flour, protein powder, and cocoa powder until no streaks are left.
Heat a skillet over medium-low heat. Coat the skillet with non-stick spray or use a little bit of butter.
Pour about ¼ cup of batter onto the pan. Sprinkle the pancake with a few chocolate chips (optional). Allow the pancake to cook for 2-3 minutes, then flip and cook on the other side. Repeat with the remaining batter.
Serve the pancakes with maple syrup, honey, or a drizzle of peanut butter. Add fresh fruit as well!
