A make-ahead cinnamon roll casserole with a creamy custard and cream cheese glaze, perfect for a stress-free Christmas morning breakfast.
For best texture, refrigerate overnight. Use room temperature eggs for smoother custard. Let casserole rest before glazing to prevent glaze from melting. If edges brown too quickly, tent with foil.
