Combine Ingredients: In a small bowl, whisk together the beaten egg, almond flour, and shredded cheddar cheese until well combined and smooth, about 30 seconds.
Season to Taste: Add a pinch of salt, pepper, and any optional seasonings like garlic powder or fresh herbs if desired, then stir to combine.
Rest the Batter: Let the mixture sit for 1-2 minutes so the almond flour can fully absorb the egg, creating a slightly thicker batter.
Preheat Waffle Iron: Preheat your waffle iron to medium-high heat and lightly grease it with cooking spray.
Cook the Chaffle: Pour half the batter into the center, sprinkle a pinch of extra cheddar cheese on top, close the lid, and cook for 3-4 minutes until golden and crispy on the outside.
Remove and Cool: Using a thin spatula, carefully lift the chaffle from the waffle iron and transfer to a plate or wire rack to cool for 1-2 minutes.
Repeat: Cook the remaining batter in the same way to create a second chaffle.
Serve: Enjoy your chaffle warm and crispy, either on its own or with your favorite dipping sauce like sour cream, ranch dressing, or salsa.
