Kirby travels to San Diego to join Icing Smiles, a group making special cakes for medical kids and their families. Kirby's baking skills are put to the test as he attempts a baking challenge in order to get in the kitchen. Next, Kirby meets a young girl and her family celebrating five years cancer free, and they'd love a cake to celebrate. Kirby and the team don't have a lot of time and have to work through the night to make their deadline.
