Preheat your waffle maker so it’s fully heated before adding the batter. In a medium mixing bowl, whisk the eggs until slightly frothy. Add shredded mozzarella, almond flour, powdered sweetener, baking powder, vanilla extract, cinnamon, and a tiny pinch of salt if using. Stir until the mixture is evenly combined. The batter will appear slightly thick with visible cheese strands, which is perfectly normal.

Lightly grease the waffle maker plates if needed to prevent sticking. Spoon half of the batter into the center of the waffle maker and close the lid gently. Allow the chaffle to cook undisturbed until golden brown and lightly crisp. Cooking times vary depending on the appliance, but patience is key — opening too early may cause tearing.

Carefully remove the cooked chaffle and repeat with the remaining batter. Let the chaffles cool for a minute or two on a rack or plate. This brief resting period allows the texture to set, creating a more donut-like softness inside while preserving a lightly crisp exterior.

For a classic donut finish, sprinkle additional cinnamon and powdered sweetener over the warm chaffles. You can also drizzle sugar-free glaze or top with whipped cream. Serve immediately for the best texture and flavor experience.
