A quick and easy breakfast casserole that transforms store-bought cinnamon rolls into a gooey, custardy delight perfect for lazy weekends or brunch gatherings.
Do not skip the soaking step; refrigerate the casserole for at least 30 minutes or overnight to allow the custard to fully penetrate the dough. Tent with foil if edges brown too quickly. Use room-temperature eggs and dairy for best custard texture. Butter the baking dish generously to prevent sticking.
