Preheat waffle maker. In a large mixing bowl, whisk eggs, yogurt and milk. Add oat flour and protein powder; whisk until well combined.
Make waffles according to your waffle maker's instructions. The amount of batter will depend on the size of your waffle maker. I use a large ice cream scoop of batter per waffle.
Cook waffles for 4-5 minutes until golden brown and crispy.
Serve hot with your favorite waffle toppings.
Notes
Store: Refrigerate for up to a week or freeze for up to 6 months.
Prevent sticking: Once preheated, give your waffle iron a light spray with cooking spray.
Topping ideas: Fruit (especially berries), whipped cream or whipped coconut cream, and maple syrup.
