Beat the eggs with the milk and vanilla in a wide shallow bowl.
Soak the bread halves in the eggy mixture for 5 minutes a side.
Heat the butter and oil in a frying pan/skillet, fry the egg-soaked bread until golden and scorched in parts on both sides.
Put the sugar onto a plate and then dredge the cooked bread until coated like a sugared doughnut.
