In a shallow dish or bowl, beat the eggs with the milk, cinnamon and vanilla until blended
Soak each slice in the egg mixture, turning several times
Meanwhile, melt the butter in a large, heavy skillet until bubbling. Add soaked slices to the pan and cook until golden brown on one side, about 2 minutes
Turn and cook on the second side for about 2 more minutes. Repeat with the remaining egg-soaked bread slices
Serve with maple or fruit syrup and powdered sugar.
