Just made these for the first time last night.
1 cup mozzarella
1/2 cup Parmesan
2 eggs
1/2 tsp baking powder to make it light and airy

Made several batches and a pizza crust. My favorite was some I just put on an oiled cookie sheet. Cut it with a pizza cutter to make cheese strips.

Pretty yummy. Waffles were delicious too. I wish I'd have known about this sooner.
