If you want to be particularly diligent about keeping your cake fresh, store it in a positively airtight container. If it came in a nice cardboard box that you don't want to undo, wrap the box in plastic wrap. If you made the cake, seal it in a plastic cake storage container. Store your cake at room temperature and keep it out of the direct sun and away from any major heat sources that might melt the icing.
