Preheat the oven to 350°F. Butter a 10 x 14-inch baking dish with the room-temperature butter.
Whisk the eggs in a large bowl. Whisk in the cream, milk, brown sugar, vanilla, and cinnamon. Add the bread, chocolate, and dried cherries and stir well, then mix in the melted butter. Pour into the prepared dish.
Bake until firm when pressed in the center, about 1 hour. Cool on a wire rack until just warm, about 20 minutes. Serve warm.
