A simple and indulgent breakfast casserole made by soaking store-bought cinnamon rolls in a rich custard overnight and baking to golden perfection. Perfect for busy mornings or special occasions.
Cut cinnamon rolls into quarters for better custard absorption. Let soak overnight for best texture. Brush melted butter on top before baking for a golden crust. Tent with foil if edges brown too quickly. Can add nuts or fruit layers for variation. Use gluten-free or vegan substitutes as needed.
