Four expert cookie makers have hosts Jet Tila and Rosanna Pansino thinking twice before taking a bite of their hyper-realistic body part cookies. Then, the cookiers find their inner witch to work their magic on 3D cookie cauldrons. To make sure one bite is all it takes to fly out of the lab with the $10,000 prize and the title of Halloween Cookie Champion, these brews will be made using potent ingredients like lavender, dried chilis, fennel pollen, truffle oil and balsamic vinegar.
Oh no! An ancient mummy is haunting the Fermentation Lab, munching on umami-filled ingredients like stinky cheese. This gives John Henson the idea for "umummy" desserts, and he tasks the bakers with creating sweet mummy treats that feature umami ingredients like red miso, aged parmesan, gochujang or soy sauce. Then, it's "bone appetit" for judges Carla Hall, Zac Young and Stephanie Boswell as the bakers get inspired by the lab skeleton, Skelly, to create Skelly's forgotten desserts, where they must use Halloween mini chocolate bars to create skeletal desserts.
