Six of America's best baking duos begin their quest for wedding cake domination and the $25,000 prize as hosts Tara Lipinski and Johnny Weir hit them with their first challenge: creating a cake topper that showcases a city of love. In the cake round, the bakers must create a dream wedding cake for Andrea and Jered, a couple of professional puppeteers who want a blend of a traditional wedding design for her and a puppet theme for him. The couple chooses their favorite cake to have at their wedding, and expert judges Kimberly Bailey, Maneet Chauhan and Randy Fenoli decide which team is sent home.

Hosts Tara Lipinski and Johnny Weir challenge the five baking teams to make a cake topper that's an ode to music. Then the teams meet their clients, Ashley and Phil, who got engaged while dancing. Phil posted the video online, and it went viral with more than 3 million views! The bakers are tasked with creating a wedding cake that reflects the couple's love of dance and showcases Ashley's favorite flavor, cheesecake. The couple chooses their dream wedding cake, and judges Kimberly Bailey, Maneet Chauhan and Randy Fenoli surprise everyone when they name the team that's going home.

The first challenge for the four remaining teams is to create cake toppers that pay homage to online dating. Then hosts Tara Lipinski and Johnny Weir introduce the bakers to their clients, Stephanie and Stephanie, a couple with the same name who met online. The bakers are challenged with combining Stephanie P.'s love of nature with Stephanie L.'s fondness for steampunk. As for flavor, they both love peanut butter and chocolate but ask the bakers to surprise them with a twist. Judges Kimberly Bailey, Maneet Chauhan and Randy Fenoli decide which three teams move on to the finale.

In the grand finale, the last three teams of bakers start by making lifelike flower cake toppers. For their final cake challenge, the teams must bake epic cakes that exude New England glam for Ashley I. and Jared, two lovebirds who fell for each other in front of the world on Bachelor in Paradise. Judges Kimberly Bailey, Maneet Chauhan and Randy Fenoli make the final decision of which team wins $25,000 and is crowned the Wedding Cake Champions.
