This week's challenge is all about Christmas cookies. Armed with only their skills, their imaginations and drive to win, these bakers compete in three challenges: Signature Bake, showcasing their family recipes as they create two sets of cookies that are both delicious and unique; Technical Bake, a surprise recipe where they must demonstrate precision and technique; and finally, The Showstopper Bake, where the bakers are asked to create elaborate flavorful gingerbread houses.
