In a mixing bowl, combine oat flour, maple syrup, one whole egg, and two egg whites. Whisk until smooth. Allow to rest for 5-10 minutes.

Preheat a non-stick skillet over medium heat and coat lightly with oil or butter.

Pour 1/3 cup of batter into the skillet, swirling to form a thin layer. Cook for 1-2 minutes until edges lift, then flip and cook for another minute.

For the filling, mix Greek yogurt, sweetener, and ground cinnamon until smooth.

Spread filling over each crepe, roll tightly, and repeat with remaining crepes.

Mix sweetener and cinnamon for topping, then serve crepes warm with additional toppings if desired.
