Peel and cut the banana into large chunks.
Add to a blender eggs, banana and protein powder. Process until you get a smooth batter and no chunks of banana are left. Do not overblend the batter.
Preheat a non-stick skillet or griddle over medium heat, greased with a small amount of oil or butter.
Pour one scoop of batter into the hot and greased pan. Cook pancakes over medium heat until the underside is golden and bubbles begin to appear on the surface, then flip with a spatula and cook on the other side until golden.
Serve immediately with your favorite toppings. Or, if meal prepping, let them cool and keep stored in an airtight container in the fridge for up to 4 days.
