This cake can be stored in an airtight container in the refrigerator for up to 1 week, making it a great make-ahead dessert for catering events. Just be sure to remove the cake from the refrigerator about 30 minutes before serving to allow it to come to room temperature and soften slightly, which will make it easier to slice and serve.
