Hosts Ann Pornel and Alan Shane Lewis welcome four champion bakers from seasons past to The Great Canadian Baking Show Tent for the chance to become the Holiday Star Baker. Winners from Seasons 2 through 5 – Andrei, Nataliia, Raufikat, and Vincent – join together for three yuletide challenges. In the Signature Bake, they each must prepare a creative interpretation of Cookies and Milk in tart form to leave out for Santa Claus. Then in the blind-judged Technical Bake they're tasked with baking Sufganiyot, a deep-fried jam and custard filled donut traditional to Hanukkah. Finally, the bakers present a Show Stopping Baking Gift Exchange featuring elaborate desserts hidden inside handmade cookie boxes decorated for the season. Judges Bruno Feldeisen and Kyla Kennaley taste and deliberate on each bake to determine the winner.
