Step 1: Prepare Your Waffle Maker - Preheat your waffle maker according to the manufacturer’s instructions.
Step 2: Mix the Dry Ingredients - In a large mixing bowl, combine the all-purpose flour, granulated sugar, baking powder, baking soda, and kosher salt. Whisk together until well blended.
Step 3: Combine the Wet Ingredients - In another bowl, whisk together the egg yolks, whole milk, vegetable oil, and pure vanilla extract until smooth.
Step 4: Beat the Egg Whites - In a clean mixing bowl, use a whisk or electric mixer to beat the egg whites until soft peaks form.
Step 5: Combine Wet and Dry Ingredients - Pour the wet ingredients into the dry ingredients and stir gently until just combined. Be careful not to overmix; some lumps are okay!
Step 6: Fold in the Egg Whites - Gently fold the beaten egg whites into the batter using a spatula.
Step 7: Cook the Waffles - Spray the preheated waffle maker with a light coat of cooking spray. Pour the recommended amount of batter into the center and cook until golden brown, about 5 minutes.
Step 8: Serve and Enjoy - Carefully remove the waffles and serve them hot with your favorite toppings.
