In a bowl, combine protein powder with oat flour and baking powder. Add egg, Greek yogurt, and optionally maple syrup or honey.
Start mixing while pouring in the milk gradually, until the pancakes batter reaches a smooth consistency (see notes*).
Pour one scoop of batter into a hot and greased pan. Cook your pancakes over medium heat until the underside is golden and bubbles begin to appear on the surface, then flip with a spatula and cook until golden. Do not overcook.
Serve with your favorite toppings or store in the fridge for a maximum of 5 days.
