1 teaspoon brandy-based orange liqueur (such as Grand MarnierĀ®)
1/4 teaspoon salt
Directions
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.
