Johnny Weir and Tara Lipinski task the five remaining teams with making the ultimate destination beach wedding cake topper. Then the teams meet their next client, a lively couple getting married on the beach in Mexico. The couple wants their cake to include their favorite things about Mexico, like vibrant colors, beaches, Dia de los Muertos and margaritas. The judges send one baking duo out with the tide, but the four surviving teams surf closer to $25,000.

Tara Lipinski's dog Dublin joins the four remaining teams to introduce a precocious pet topper challenge. Then Johnny Weir and Tara introduce an engaged couple, who ask the bakers to combine their love of nature with their love of the city. They both like cookies more than cake, so the bakers must find common ground. Judges Kimberly Bailey, Maneet Chauhan and David Tutera will send three teams to the finale.

The final three teams must make a first anniversary celebration cake for Tara Lipinski and her husband, Todd Kapostasy. The couple wants to capture all of their travels on one cake, plus they have an untimely surprise for the competitors. In the end, judges Kimberly Bailey, Maneet Chauhan and David Tutera will select one team to earn the title of Wedding Cake Champion and the $25,000 grand prize!
