Start by greasing your waffle iron with oil and preheating it. In a medium-sized bowl, combine the coconut flour, protein powder, baking powder and egg.
Whisk to blend until the ingredients are thoroughly mixed.
Stir in one tablespoon of water at a time until the mix forms a thick pancake batter.
Spoon the batter onto the waffle iron.
Cook waffles until crisp and then serve with your choice of yogurt or syrup.
