I don't know anyone who doesn't love receiving a box of delicious cookies, especially when it's a surprise! Once your cookies have completely cooled and the icing has hardened, you can package them up. Place two cookies back to back and wrap in plastic wrap. Keeping them this way allows them to support each other but also keeps them separate enough to not stick together and get all clumpy. This may be a little more difficult in the summer heat, so this may work better if you're living in colder climates. Then, add the plastic-wrapped cookie pairs to a decorated box, and voila!
