Valerie Bertinelli and Duff Goldman are lost in space and challenge the three remaining bakers to create cakes that look like a spaceship, aliens or another planet. The most out-of-this-world cake wins, and only one baker will claim $25,000, a spot in Food Network Magazine and the title of Kids Baking Champion.

The young bakers must think on their feet as Valerie Bertinelli and Duff Goldman challenge them to fill a mini fireplace mantel with "santastic" sweets. Special guest Casey Webb helps choose the winner of the baker's dream prize package of top-of-the-line baking equipment worth over $10,000.
