Instructions

• Preheat your waffle iron according to the manufacturer's instructions.
• In a medium bowl, whisk together 1 1/2 cups all-purpose flour, 1/2 cup cornstarch, 1 tsp baking powder, and 1/2 tsp baking soda until evenly combined.
• In a separate bowl, whisk together 1 1/2 cups buttermilk, 3/4 cup vegetable oil, 1/2 cup whole milk, the 2 egg yolks, 2 tbsp sugar, and 1 tsp vanilla extract until smooth.
• Pour the wet ingredients into the dry ingredients and gently stir until just combined; a few small lumps are fine—do not overmix.
• In a clean bowl, beat the 2 egg whites until soft peaks form.
• Gently fold the beaten egg whites into the batter in two additions, folding just until no large streaks remain.
• Lightly brush or wipe the preheated waffle iron with a small amount of vegetable oil. Pour an appropriate amount of batter into the iron (follow your waffle iron’s capacity), close, and cook until the waffles are browned and crisp.
• Remove the waffles and repeat with the remaining batter. Serve immediately.
