Before you start mixing ingredients, preheat your waffle iron according to the manufacturer’s instructions. A hot iron means crispy waffles, and nobody likes a soggy bottom!

In a large bowl, combine the all-purpose flour, rice flour, baking powder, salt, smoked paprika, cayenne pepper, and onion powder. Give it a good whisk to ensure all ingredients are evenly distributed. This step is fundamental; it helps the baking powder activate properly and allows for even cooking.

In another bowl, whisk together the egg yolks, melted butter, and buttermilk until fully blended. This mixture should be smooth and well combined.

Pour the wet mixture into the dry ingredients. Use a spatula or wooden spoon to mix gently. You want to combine them without overmixing. A few lumps are okay—that will help keep the waffles tender.

In a separate bowl, beat the egg whites until stiff peaks form. This is the secret to fluffy waffles. Once they are ready, gently fold them into the batter. Be careful not to deflate the egg whites; fold until just incorporated.

Now, fold in the grated cheddar cheese and chopped chives. Make sure they are evenly distributed in the batter. The cheese should be mixed in gently so it’s spread throughout the waffles.

Spray your waffle iron lightly with cooking spray or brush with a bit of melted butter. Pour the batter into the iron, ensuring not to overfill it. Cook according to the waffle iron’s instructions, usually about 5 minutes or until golden brown.

Once cooked, carefully remove the waffles from the iron. You can keep them warm in a low oven while you cook the remaining batter. Serve your savory cheddar cheese waffles with your choice of toppings, like bacon, avocado, or a drizzle of maple syrup.
