1In a large mixing bowl, whisk together the eggs, skim milk, vanilla extract, and ground cinnamon until well combined.
Preheat a non-stick skillet or griddle over medium heat and add the unsalted butter, allowing it to melt and coat the surface.
Dip each slice of whole-grain bread into the egg mixture, ensuring both sides are well coated.
Place the coated bread slices onto the skillet or griddle and cook for 2-3 minutes on each side, or until golden brown.
Remove the French toast from the skillet and serve warm, drizzled with maple syrup.
