Process rolled oats in a high-speed blender until they reach a fine, flour-like consistency.
Combine oat flour, protein powder, and salt in a mixing bowl.
Whisk in egg whites, almond milk, and vanilla extract until the batter is smooth and free of lumps.
Allow the batter to rest for 5 minutes to let the oats hydrate.
Preheat a non-stick skillet over medium heat and lightly grease with coconut oil.
Pour 1/4 cup of batter into the center of the pan, tilting and rotating the pan immediately to spread the batter into a thin circle.
Cook for 60 to 90 seconds until the edges start to lift and the bottom is golden brown.
Carefully flip the crepe with a spatula and cook the other side for an additional 30 to 45 seconds.
Repeat with the remaining batter and serve immediately.
