Winner Cake All: Darci Lynne's Birthday

Giada De Laurentiis challenges four of the best baking teams to create a cake decoration that honors members of the armed services coming home. After this round, one team departs, and the remaining three meet their special client. Mariana's husband, Dustin, is returning home from overseas, so she and her father-in-law are throwing a big bash to celebrate. They task the bakers with making a cake inspired by Dustin's childhood memories that he wants to pass down to his newborn son -- who he hasn't met yet! The winning team wins $10,000 and the honor of serving their cake at a celebration fit for a hero.
