Ingredients

• 1 stick (1/2 cup) unsalted butter
• 1 cup packed brown sugar
• 2 tablespoons corn syrup
• Loaf of bread
• 5 large eggs
• 1 1/2 cups half-and-half
• 1 teaspoon vanilla
• ¼ teaspoon cinnamon
• 1/4 teaspoon salt

In a small heavy saucepan melt butter with brown sugar and corn syrup over moderate heat, stirring, until smooth and pour into a 13- by 9- by 2-inch baking dish. Cut 1-inch thick slices of bread, reserving ends for another use. Arrange bread slices in one layer in baking dish, squeezing them slightly to fit. In a bowl whisk together eggs, half-and-half, vanilla, and salt until combined well and pour evenly over bread. Chill bread mixture, covered, at least 8 hours and up to 1 day.

Preheat oven to 350° F. and bring bread to room temperature.  Bake bread mixture, uncovered, in middle of oven until puffed and edges are pale golden, 35 to 40 minutes.   Flip once half way through. via
