Step 1

In a bowl beat the egg white until stiff peaks form. Set aside.

Step 2

In a medium bowl, combine the flour, cornstarch, baking powder, baking soda, and salt; mix well.

Step 3

Add the milk, butter, egg yolk, sugar and vanilla and mix just until combined. Do not overmix as you do not want air in this. Some lumps are OK.

Step 4

Gently fold in the egg whites until combined. Do not deflate the egg whites. This is what will give your waffles that light texture.

Step 5

Let the batter sit for 30 minutes.

Step 6

Heat a waffle iron.

Step 7

Follow the directions on your waffle iron to cook the waffles.

Step 8

Serve immediately hold in a 200 degree oven, directly on the rack. I would not recommend stacking them as they are heavy and may get smushed or soggy on the plate.
