Edible stained glass is one of the most colorful and bewitching trends in the cookie world, and four cookie experts make glowing Halloween stained glass cookies for hosts Duff Goldman and Rosanna Pansino. After one cookier is eliminated, the remaining three masters build giant, elaborate Halloween funhouses that would thrill any Halloween carnival-goer. The judges will really feel like they are at a carnival as the bakers must incorporate fun fair flavors like caramel apples, grilled corn, popcorn balls and deep-fried sandwich cookies. One talented contestant will take home a sweet $10,000 prize.
