01 - Preheat your waffle maker according to the manufacturer's instructions until the indicator light signals it's ready for cooking.
02 - Crack eggs into a medium mixing bowl and pour in almond milk. Whisk vigorously until the mixture is uniform and slightly frothy.
03 - Add shredded cheddar, Parmesan, diced ham, almond flour, baking powder, garlic powder, black pepper, and salt to the egg mixture. Stir thoroughly until all ingredients are evenly distributed and a thick batter forms.
04 - Lightly coat the waffle maker plates with nonstick cooking spray or a small amount of oil to prevent sticking.
05 - Pour half of the batter into the center of the preheated waffle maker. Use a spatula to spread the batter evenly toward the edges. Close the lid firmly and cook for 4 to 5 minutes until golden brown and crispy.
06 - Carefully open the waffle maker and remove the cooked chaffle. Repeat the cooking process with the remaining batter.
07 - Transfer chaffles to a wire cooling rack for 2 to 3 minutes to maintain crispiness. Serve warm while still crispy.
