The signature bake for cookie week has the bakers making eighteen linzer cookies apiece in ninety minutes. Beyond the uniformity between the eighteen and the bake itself, the bakers have to ensure the rolling of the dough is even, the flavors of the cookie and its filling are complimentary - they able to go outside the traditional - the filling is distributed right to the edge of the cookie without overflowing, and that the filling reaches just to the top of the cookie in its distinctive "window". They have to make another sandwich cookie for the technical, the Dutch stroopwafel which is caramel-filled. They have to make twelve uniform cookies apiece, be sure to pay attention to the timing as it is a matter of seconds between it being underdone and overdone, that the cookies are cut into perfect rounds, and that the caramel itself has a nice stretch when the cookie is pulled apart. The bakers have one and three-quarter hours for the challenge. And for the showstopper, the bakers have three and a half hours to make a two or three dimensional "family portrait" out of cookie. The term family is up to each baker to define, they must include two different types of cookies, and royal icing must be used.
