Step 1

Preheat a waffle maker.

Step 2

Whisk egg in a small bowl and stir in mozzarella cheese.

Step 3

Pour 1/2 of the batter onto the preheated waffle maker, spreading it out from the center with a spoon. Close the waffle maker and cook until the steaming stops and the chaffle is well browned, about 3 minutes. Don't overcook, as that will make it chewy. Repeat process with remaining batter.
