Preheat the oven to 350 F degrees.
Spray a 13x9-inch baking dish with cooking spray.
Arrange bread slices in a prepared dish, overlapping slightly, Arrange peaches over bread.
In a large mixing bowl, whisk together eggs, milk and cream, sugars, preserves, vanilla, cinnamon, and salt. Pour over peaches and bread slices. Pour melted butter over the casserole. Spray a sheet of foil with cooking spray and place it over the casserole. Spray side down, sealing. Refrigerate overnight for about 8 - 12 hours.
Bake, covered for 30 minutes. Uncover, bake until lightly browned, 12-15 minutes more. Let stand for 10 minutes.
Make the cream icing: with a hand-held blender, mix ingredients until thickened to a syrup consistency. Stop beating at that point so it doesn't become too hardened-thick. You want it to be able to flow over the bread pudding.
Garnish: Fresh peaches, fresh raspberries, mint leaves.
Enjoy! Buon Apetito!
