Certain cookies tend to ship better than others do. We recommend that you do not mail cookies with custard or custard-like fillings or toppings, including cheesecake bars or Nanaimo bars. The custard could spoil, making a very unwelcome gift. For that matter, any cookie that requires refrigeration is not a good candidate for the mail. Another type of cookie that doesn't hold up well for mailing is one with a delicate, cake-like texture such as Madeleines. And now, on to the kinds of cookies that can be mailed all over the world
Dense bar cookies such as fudge brownies, blondies and peanut butter bars travel well too. Be sure to individually wrap each one with plastic wrap to keep that moist, dense crumb from drying out.
Macaroons and pignoli mail beautifully. Their chewy, moist textures only seem to improve after they've aged a few days.
Cookies that have a slightly chewy texture, like chocolate chip, oatmeal, snickerdoodles, and white chocolate-cranberry cookies also ship well. These cookies tend to dry out if they are in the mail for more than a week, so if their destination is a long way off, you might want to ship them by express mail to ensure that they arrive just as tasty as when they were baked.
Cookies that have a crunchy or hard texture such as biscotti, Mexican wedding cakes, crisps, Springerle, and shortbreads make excellent choices for mail delivery. They tend to be fairly sturdy, so you don't have to worry too much about breakage. And since they already have a fairly dry texture, drying out isn't much of an issue.
Once you've baked and cooled your cookies, you're ready for the next step: packing them. There are a few guidelines you should follow when it comes to preparing cookies to be mailed. Follow these and your special packages should arrive fresh, in one piece, and great-tasting.
