Scrape seeds out of the vanilla bean, if using. Add seeds, if using, or extract if not, flour, baking powder, coconut sugar, egg replacer in a bowl. Add 1 1/2 cups water and melted butter. Mix well. Batter might be slightly lumpy. Pour by the 1/4 cupful* onto greased, hot waffle iron and cook according to manufacturer's directions. (Leave waffles slightly undercooked for freezing and toasting later.)
