Add the oats to a blender and blitz until it resembles fine flour to make the protein pancakes.
Add the protein powder, baking powder, egg, milk and cinnamon to the blender too and blitz everything until you have a texture like a pancake batter.
Heat a lightly oiled frying pan over medium-high heat. Pour the mixture onto the pan, using approximately ΒΌ of the total mixture for each protein pancake.
Tilt the pan in a circular motion so the batter coats the surface evenly.
Cook the pancake for about 50 seconds until the bottom is light brown. Loosen with a flexible spatula or fish slice, flip over and cook the other side. Serve hot with your filling of choice.
