The recipe works well with spelt flour, white flour, or some brands of all purpose gluten free flour. I cannot vouch for results using almond flour or coconut flour. If you choose a liquid sweetener like maple syrup or honey, decrease the water by two tablespoons.

To make protein waffles, whisk dry ingredients well. Stir in wet to form a batter. Depending on the type of protein powder, you may need to add more liquid a tablespoon at a time to achieve a pancake or waffle batter texture.
