Atlanta's Ultimate Sugar Show is one of the biggest events on the competitive baking calendar. Events for cake decorating, cookie decorating, sugar art and a tasting competition for Southern-themed desserts ensure that anyone who is anyone in the competitive sweets business will be in attendance. RaChelle enters a cake depicting a fireman saving a baby and a cookie of a family visiting their quarantined grandmother. RaChelle's Cookie Con victory means she's in a more experienced category at this event, which also means anxiety is high. She will face off against wildcard decorator Lili, whose chosen frontline worker is a librarian, honoring her fiancé. Anamaria brings her cheesecakes with a Northern California spin on the Southern classic red velvet cake, and Delaware's Monty uses his cupcake recipe to build a national brand for his business. All eyes will be on Maythe, who is competing in multiple categories as a professional and hoping to leave a big enough impression for nobody to ever mispronounce her name at a competition again.

The bakers all try to win "Best in Show" at the Ultimate Sugar Show in Atlanta. Maythe's doctor sculpture is a hit with judges, but she faces stiff competition. Lili and RaChelle compete against one another with their Frontline Hero sculpted cakes, while Anamaria and Monty try to beat the locals at their own game in The Great Southern Bake-Off.
