If you do not have a krumkake iron, you can use a small nonstick pan. Just add a few tablespoons of milk to the batter to loosen it up, since you don't have the pressure of the iron to spread it out. Pour 1 tablespoon of the batter into the center of the pan, and, using your tablespoon, spread the batter into a circular shape. Cook for 1 minute. Flip and continue to cook for 1 minute more. Remove with a rubber spatula and roll with the krumkake mold immediately. If you do not have a krumkake mold, wrap a sugar cone with aluminum foil and use this to mold your waffle cookies.
