Preheat oven to 350°F. Grease an 8-inch square glass baking dish and set aside.
Combine eggs, milk, sugar, butter, 1 tsp. cinnamon and salt in large bowl.
Place bread in prepared baking dish and pour milk mixture on top. Mix and submerge all bread pieces. Sprinkle top with remaining 1 Tbsp. sugar and 1/2 tsp. cinnamon.
Set the baking dish in a larger baking pan and pour hot water in, to about 1-inch from the top of the dish.
Bake 45 minutes, or until a knife comes out clean. Remove from oven and let cool slightly.
