Preheat your waffle maker until fully hot. Lightly coat the plates with cooking spray or a thin swipe of butter.
In a small bowl, whisk the eggs until smooth. Add the shredded cheese, almond flour, Parmesan, baking powder, garlic powder, salt, and pepper.
Stir until evenly combined. The batter will be thick and a bit chunky—that’s perfect.
If using add-ins like scallions or bacon, fold them in now. Avoid large, watery vegetables; they can make the chaffle soggy.
Spoon about 2–3 tablespoons of batter onto the hot mini waffle maker, spreading slightly to the edges.
Close the lid and cook for 3–4 minutes, or until deeply golden and crisp.
Carefully lift the chaffle out with a silicone spatula and place it on a wire rack to keep the bottom crisp. Repeat with the remaining batter.
Serve hot as is, or top with a fried egg, avocado slices, and a sprinkle of hot sauce for a complete breakfast.
