This is our favourite type of waffles. They normally are eaten hot, but the leftovers are very good cold as well.
- Mix together flour, egg yolks, sugar, salt and the milk until you obtain a dough without lumps.
- Add the melted butter and the whipped egg whites.
- Bake in a hot waffle iron. You only need to grease it for the first waffle if you're using an non-stick waffle iron.
- Serve hot with some powdered sugar on top.
