Baking is a therapeutic holiday pastime. Your home smells like warm sugar and the windows fog up. Cookies are perfect for entertaining, but have a relatively short shelf life, and don't travel well. I've had tins shipped to me from across the country, and by the time they rattled to my door, they were broken up and crumby.

Festive Rice Krispie Balls
