In a bowl, whisk the eggs until well beaten.

Add the shredded mozzarella cheese and baking powder (if using) to the eggs. Mix until well combined.

Preheat a waffle iron according to the manufacturer's instructions.

Pour half of the batter into the waffle iron, spreading it evenly.

Close the waffle iron and cook until the chaffle is golden brown and crispy, about 3-4 minutes.

Repeat with the remaining batter.

Remove the chaffles from the waffle iron and let them cool slightly.

Serve warm. These can be enjoyed plain or used as a base for various toppings
