Apple Cinnamon French Toast

Combine syrup, butter, and brown sugar in a sauce pan; bring to a boil and simmer uncovered for several minutes or until syrup-like consistency. Whisk eggs, milk, vanilla, salt and cinnamon in a mixing bowl. Pour syrup mixture into the bottom of a 13 x 9 x 2-inch baking pan. Layer apple slices in the syrup. Lay the bread slices on top of the apples. Pour egg mixture over all, cover and refrigerate overnight. Bake at 350 °F (175°C) for 1 hour. Cut into squares and invert to serve. Sprinkle with powdered sugar and serve.
