A cozy and effortless breakfast casserole made by soaking cinnamon rolls in a spiced custard overnight, then baking to a golden, custardy perfection. Perfect for busy mornings or special occasions.
Do not skip the overnight soak for best custardy texture. Use room temperature eggs for smooth custard. Tent with foil if top browns too fast. Let casserole rest after baking for easier slicing. For dairy-free, substitute milk and cream with almond or oat milk and coconut cream, and use vegan butter.
