In a medium bowl, whisk together eggs, milk, cinnamon, maple syrup, and vanilla extract until combined.
Pour egg mixture over bread cubes. Cover with aluminum foil and refrigerate for at least 30 minutes, or preferably overnight.
While bread is soaking up egg mixture, or when ready to bake, preheat oven to 350° F. Bake for 15 minutes with the aluminum foil on. After 15 minutes, remove foil and continue to bake for an additional 15-20 minutes until golden brown.
