The holidays are here, and the Kids Baking Championship kitchen heats up as four fan-favorite kid competitors return for a new challenge. Host and judge Duff Goldman is joined by Season 4's Abby Martin, who offers her unique perspective as a former contestant. Duff asks the returning competitors to make a holiday candle tsunami cake with a poured sugar flame, and the best baker will win the ultimate $10,000 baker's prize package complete with a blast chiller!

The Kids Baking Championship snack mine is the inspiration for this week's challenge as hosts and judges Valerie Bertinelli and Duff Goldman ask the 11 young bakers to use three snack items -- potato chips, pretzels and chocolate candies -- in one delicious kitchen sink dessert. In the end, one baker goes home.
