Mix wheat flour, baking soda, vanilla sugar and salt in a bowl.
Whip small amounts of milk, orange juice and oil into the bowl at a time, preferably with a balloon whip.
When you have a smooth batter without lumps, pour your waffle batter in to a hot Belgian waffle iron and cook.

7 cup wheat flour
2 teaspoon baking powder
2 tablespoon sugar
1 teaspoon vanilla sugar
A pinch of salt
6 cup plant milk of choice
