Beat egg whites until soft peaks for, set aside.

Sift all dry ingredients together (or whisk them together).

Beat egg yolk in another bowl for 1 minute, then mix in milk, oil, and vanilla.

Combine the dry ingredients with the milk mixture. Stir only until blended. Fold in egg whites.

Cook in waffle iron. This will make 4 Belgian waffles. I also have a Mickey Mouse waffle iron and I can get 9 waffles from there.
