In the season finale, the final three teams are squaring up in an epic showdown. It's nearing the time for the Scout Elves to head back to the North Pole to help Santa prepare for Christmas Eve. As they return home, they will fly over their favorite places on Earth, so host Duff Goldman challenges the sweetmakers to "elf-ify" a famous landmark in their honor. In the end, judges Kardea Brown and Ashley Holt crown their Ambassadors of Confectionery Concoctions and award them $25,000!

It's always better to give than to receive, which is why the Scout Elves want to make sure that Santa has a sweet new ride, but they had some mechanical trouble during the sleigh's yearly tune-up. Host Duff Goldman revs up the teams as they create an edible sleigh design that will wow Santa and show off their magical skills. Then, two teams go head-to-head in the Santa Showdown by creating inventive snow forts, where they will partake in an epic snowball battle to win a Christmas miracle from judges Kardea Brown and Ashley Holt.

Christmastime means holiday music is all around. The Scout Elves want to play the 12 Days of Christmas at their elf concert tonight, but they accidentally mixed up all the lyrics! Host Duff Goldman tasks the remaining teams with figuring out their jumbled lyrical prompts and delivering a twisted-up 12 Days of Elfmas showpiece that will get judges Kardea Brown and Ashely Holt's toes tapping. The bakers will have to really impress to avoid being sent dancing home.

One of the biggest decisions families make every year is which photo they are going to use for their Christmas card! Host Duff Goldman challenges the bakers to help their Scout Elves take an "elfie selfie" by creating an edible diorama with the perfect backdrop for their photos. Then in the Santa Showdown, two teams design an edible holiday outfit which needs to be runway ready for judges Kardea Brown and Ashley Holt's elf fashion show. In the end, one team goes home.

Magic is in the air at the Enchanted Cottage, the whimsical and wondrous culinary playground that the Scout Elves have created for six teams of hopeful contestants. In round one, host Duff Goldman asks the teams to adopt their own Scout Elf and create a personalized edible shelf for their elf to enjoy. The two bottom teams face off in the Santa Showdown, where they will have to pull out all the stops to impress judges Kardea Brown and Ashley Holt with their snow globe showpieces that embody Christmas memories.
