Slice the French bread into about 2" thick slices.
In a shallow dish mix together eggs, cinnamon, and mil. In a medium bowl whip together cream cheese, 1/2 cup of sugar and vanilla.
Dunk each side of the French bread into the egg mixture.
In skillet/pan cook French Toast until golden brown, about 2-3 minutes on each side.
Place on piece of French Toast on top with your cream cheese mixture and place another piece of French Toast on top. Sprinkle remaining sugar across the top of all the "sandwiches".
You can either use a torch or place your "sandwiches" in the broiler in order to get the sugar to melt and become a nice crust.
