The remaining junior home cooks party their way into the next team challenge when they leave the MasterChef Junior kitchen for the first time to cook at a birthday party for kids ages 8-13, as well as special guests, the Ramsay and Elliot children. The team that receives the most votes from the birthday party attendees is safe from elimination, while the losing team competes in the next pressure test and create the French dessert croquembouche.

The remaining junior chefs compete for the final 12 spots in the Top 20. Making dishes ranging from cupcakes, to steak and lobster, the young chefs are tested to their limits and will find out if they will move on to the next round.

The junior chefs split up into pairs and have to decorate and frost as many specialty donuts as they can in just 10 minutes, all while being tied by the ankle to their partner! Later in the kitchen, Gordon Ramsay's daughter, Matilda, gives the contestants a masterclass on how to make her version of a hamburger and French fries. Then, the junior chefs must do their best to replicate it before the judges determine who will be sent home.
