Preheat your waffle maker: Heat a mini waffle maker (like a Dash) or a regular waffle iron. Lightly grease with cooking spray or a small pat of butter.
Mix the batter: In a small bowl, whisk the egg until smooth.
Stir in mozzarella, almond flour, baking powder, and a pinch of salt. Add any seasonings you like.
Adjust thickness: If the batter looks too thick to spoon easily, add a teaspoon of water or heavy cream. If too thin, sprinkle in a bit more almond flour.
Cook the chaffle: Spoon half the batter onto the hot waffle maker and spread lightly.
Close the lid and cook for 3–4 minutes, or until golden and set around the edges.
Let it crisp: Carefully remove the chaffle and place it on a cooling rack for 30–60 seconds to crisp up. Repeat with the remaining batter.
Serve your way: Enjoy plain, top with butter, add avocado and bacon, or use two chaffles as a quick breakfast sandwich bun.
