Preheat a skillet over medium-high heat.  

In a shallow bowl, whisk together the eggs, milk, cinnamon, and nutmeg.  

Dip each slice of bread in the egg mixture and let it soak for a few seconds.  

Place the slices of bread in the preheated skillet and cook for 2-3 minutes on each side, or until golden brown.  

Remove the slices of bread from the skillet and spread a thin layer of butter on each side.  

Place 1 tablespoon of caramel sauce in the center of each slice of bread and fold over to close.  

Place the stuffed French toast back in the skillet and cook for 1-2 minutes on each side, or until lightly browned.  

Drizzle each slice with the remaining caramel sauce and maple syrup.
