Preheat your oven to 375°F and prepare a baking pan by spraying it with cooking spray.
Cut three quarters of a loaf of brioche French toast into pieces and arrange them in the prepared pan.
In a separate bowl, whisk together the eggs, half and half, heavy cream, sugar, cinnamon, vanilla extract, and salt until well combined.
Pour the egg mixture evenly over the bread pieces in the pan.
Melt the butter and drizzle it over the top of the casserole.
Bake in the preheated oven for 30 to 35 minutes until golden and set.
Once baked, serve topped with powdered sugar, fresh fruit, and maple syrup.
