Whisk the eggs in a deep plate together with the sugar, salt, ground cinnamon, and semi-skimmed milk until smooth.

Coat the slices of white bread one by one in the egg mixture. Stack the French toast on a plate.

Pour the remaining egg mixture evenly over the stack of bread and let it soak briefly so the bread is well saturated.

Heat the butter in a large frying pan over medium heat. Cook the French toast for about 5 minutes until lightly browned, turning them halfway through for even cooking.

Divide the French toast over flat plates. Serve, if desired, with a little powdered sugar or syrup for extra sweetness. Enjoy!
