In a large metal bowl (not copper), whip with egg whites until soft peaks form.
In another bowl, whisk together the remaining ingredients except for the coconut flour.
Carefully beat this mixture into the egg whites. Fold in the coconut flour, one tablespoon at a time.
Scoop the batter onto a hot waffle iron. I used the kind that has 4 square waffles. The batter puffs up a good bit, so I just used the two back squares at once. Scoop enough batter to cover ⅔ of each waffle square.
Bake in the waffle iron for 3-5 minutes. I found that the batter took about 2-3 minutes longer to cook than normal waffles do. The waffles should get fairly browned so that the inside can get a little dry and light, yielding a crispier waffle.
