It's a Broadway Princess Party (S01E04)

Giada De Laurentiis invites four elite baking teams to craft cake decorations inspired by their beloved fairy tales. Unfortunately, one team faces elimination and departs without a fairy tale ending. The three remaining teams then meet their special guests, the stars of the Broadway Princess Party: Laura Osnes, Susan Egan, and Courtney Reed. Celebrating the third anniversary of their concert series, these princesses need a stunning cake for their cast and crew. The bakers must deliver extravagant, glittering creations worthy of royalty. In the end, one team takes home $10,000 and the chance to present their cake at a grand royal ball.
