Sieve the protein powder and buckwheat flour into a mixing bowl
Add in the egg (whites) and milk to the bowl and whisk until combined and no lumps
Heat the oil in a frying pan on a medium-high heat
Pour the batter into the pan, evenly and thinly coating the surface
Cook for 2-3 minutes (until the crepe begins to form holes)
Gently flip the crepe over with a spatula and cook for another 2-3 minutes on the other side
Repeat until you have used all the batter
Serve with your favourite toppings (I recommend berries, chocolate and a nut butter/spread)
Enjoy!
