This Great Gingerbread AT-AT was made by Blackmarket Bakery. They did a wonderful job combining Star Wars and Christmas. The broken and fallen candy canes under the AT-AT are a nice touch. I also really like the gingerbread man Luke Skywalker hanging from the AT-AT.
Moreover, check out these terrific AT-AT Cakes and Cookies.
