How to Mail Cookies When You Can't Be There in PersonSending homemade cookies is a time-honored way to show someone you're thinking of them from afar. Choose the Right Types of Cookies to MailNot all cookies travel well; certain cookies tend to ship better than others do. Don't mail cookies with custard or custard-like fillings or toppings, including cheesecake bars or Nanaimo bars. Pack cookies in a sturdy tin or airtight container but don't overstuff your container; crowded cookies could damage each other. Seal the shipping box with heavy-duty shipping tape.
