Heat oven up to 350°F.

Cut the slices of bread into cubes.

In a saucepan, heat the milk, and butter but do not allow to boil. To this, add the vanilla, beaten eggs and sugar, when a bit cooled. Add the baking powder and blend until smooth.

In an ovenproof tray, layer the cubes of bread and pour over it the liquid prepared above, until the bread is saturated.

If desired, sprinkle your choice of nutmeg, cinnamon, or raisins.

Bake for approximately 30 minutes or until it browns.
