cup unsalted butter
cup packed brown sugar
tablespoons corn syrup
(1-inch thick) slices French bread
cups half-and-half cream
teaspoon vanilla extract
teaspoon brandy-based orange liqueur (such as Grand Marnier®)
Melt butter in a small saucepan over medium heat. Mix in brown sugar and corn syrup, stirring until sugar is dissolved. Pour into a 9x13 inch baking dish. Remove crusts from bread, and arrange in the baking dish in a single layer. In a small bowl, whisk together eggs, half and half, vanilla extract, orange brandy, and salt. Pour over the bread. Cover, and chill at least 8 hours, or overnight. Preheat oven to 350 degrees F (175 degrees C). Remove the dish from the refrigerator, and bring to room temperature. Bake uncovered 35 to 40 minutes in the preheated oven, until puffed and lightly browned.
