If you are not going to eat your cupcakes the day of your order or had some left over, simply store your cupcakes in an airtight container or cover with plastic wrap.  This should give them up to two more days.  After two days the cupcake is no longer fresh and not up to the standards of InStyle Cupcakes ™.

Putting your cupcakes in the refrigerator is not recommended because, depending on the type of cupcake it could dry it out.  However, I have costumers that prefer this method and simply bring the cupcakes up to room temperature before serving.
