Instructions:

• Step 1: Preheat Your Waffle Iron - Begin by preheating your waffle iron according to the manufacturer's instructions. A hot waffle iron is essential for achieving that crispy exterior.
• Step 2: Combine Dry Ingredients - In a large mixing bowl, whisk together the all-purpose flour, cornstarch, baking powder, baking soda, and sugar until well combined.
• Step 3: Mix Wet Ingredients - In another bowl, whisk together the buttermilk, vegetable oil, whole milk, egg yolks, and vanilla extract until smooth.
• Step 4: Combine Wet and Dry Ingredients - Pour the wet mixture into the bowl with the dry ingredients. Stir gently until just combined. Be careful not to overmix; a few lumps are perfectly fine.
• Step 5: Whip Egg Whites - In a separate bowl, beat the egg whites until soft peaks form. This step is crucial for light and airy waffles.
• Step 6: Fold in Egg Whites - Gently fold the whipped egg whites into the batter. This will create a wonderful lift and help keep your waffles light.
• Step 7: Cook the Waffles - Once your waffle iron is hot, lightly grease it if necessary. Pour an appropriate amount of batter onto the waffle iron (usually about 1/2 to 3/4 cup, depending on the size of your iron). Close the lid and cook according to your waffle iron’s instructions, usually around 4 to 6 minutes or until golden brown and crispy.
• Step 8: Serve Immediately - Serve your Crispy Waffles immediately with your favorite toppings such as maple syrup, fresh berries, or whipped cream. Enjoy every delicious bite!
