Melt the butter in a nonstick frying pan. Add the bread crumbs and sauté them together over medium heat until the panko browns, set aside to cool. Cut the French bread into 2 inch thick slices. Cut an incision down the middle of each slice of bread, don’t cut through to the bottom or sides. Combine cream cheese and jam in a medium bowl and carefully spoon 1 to 2 tablespoons of the mixture into the bread, set aside. In a large flat bowl, mix together the eggs, milk, cinnamon and flavor together. Pour the flour into a plate; coat each slice of stuffed bread, coating both sides and edges. Coat each slice with the egg mixture and then roll in the toasted panko crumbs. Bake in 350° oven for 15 minutes.
