Preheat oven to 200°F. Place a rack on a baking sheet and place in oven. Arrange the bread in two 8 x 8 x 2-inch glass baking dishes.
Whisk eggs, half-&-half, salt, spices, and vanilla until smooth but not foamy. Pour the batter over bread. Turn the bread over, let sit 5 minutes, turn the bread over again.
Preheat the Griddler® in the open griddle up on 325°F. When the Griddler is hot (indicator light will turn green), arrange the soaked bread on the hot griddle. Cook until deep golden brown on each side, about 3 to 4 minutes per side. Remove from Griddler and serve or keep warm in low oven. Serve with warm Cranberry Maple Syrup.
