One of the most timeless traditions around the holidays—dating back centuries—is the baking and decorating of gingerbread houses. Covered in candy and icing, gingerbread designs have evolved from delicious treats to decorative, life-size works of art. In fact, the largest gingerbread house ever created was 21 feet tall, nearly the size of a tennis court and contained 35.8 million calories, entering the Guinness World Records in 2013. Hilton pastry chefs love to get in on the fun, revealing fantastical creations during the holiday season. Here’s a sampling of the gingerbread houses you may find when you enter a Hilton hotel or resort.
