Wrapping a glazed loaf cake can be done by allowing the glaze to set first before wrapping it in plastic wrap or parchment paper. Make sure that the glaze is completely dry to avoid sticking. For added protection, you can then wrap the loaf cake in aluminum foil to keep it fresh and prevent any potential smudging of the glaze during transportation or storage. If presenting as a gift, placing it in a decorative box with tissue paper can provide an attractive finish.
