Preheat Belgian Waffle maker. Using cooking spray, generously grease the waffle iron.

In a large bowl, whisk together the dry ingredients (flour, corn starch, baking powder, baking soda, salt, and sugar).

In a medium bowl, whisk together the egg yolks, milk, vanilla, and oil. Add the milk mixture to the dry ingredients and mix thoroughly.

In a separate bowl, whisk the egg whites using an electric hand mixer until they are fluffy and stiff peaks form. Gently fold the egg whites into the waffle batter.

Following your waffle maker's manufacturer instructions, cook the waffles.

Serve warm immediately with your favorite waffle toppings.
