A cozy and impressive breakfast casserole combining cinnamon rolls soaked overnight in a rich egg custard, baked to golden perfection and topped with sweet icing.
Use room temperature eggs and milk for a smooth custard. Do not skip the overnight soak for best texture. If the top browns too quickly, tent with foil halfway through baking. For a crispier top, sprinkle brown sugar or cinnamon sugar before baking. Frozen cinnamon rolls can be used if thawed first. Dairy-free and vegan substitutions are possible using plant-based milk and flax eggs.
