In a small bowl, whisk together melted butter, brown sugar and maple syrup. Pour mixture into a large tall baking dish and spread into an even layer using a spatula. Arrange bread on top in a single layer.
In a large bowl, whisk together eggs, milk, cream, vanilla, cinnamon, nutmeg and salt. Pour mixture over bread. If you have time, cover and let soak in refrigerate for 1 hour or up to overnight. Otherwise, bake for about 25 minutes, or until the the butter-sugar mixture is bubbling in the bottom of the pan.
Serve immediately, sugar side up. Sift powdered sugar on top if desired.
