Most episodes have two rounds. The first round is alternately called the "Preheat," the "Thriller" or the "Haunted Heat" depending on the season. Each baker must make a small dessert based on an assigned theme and often a required ingredient. The person who wins the first round gets a prize or advantage in the next round, which has varied throughout the series. For example, the advantage may be exclusive choice of ingredients or themes, assigning these to other contestants, or protection from elimination.
The second round is alternately titled the "Main Heat," the "Killer," or the "Bake for Your Life" challenge. The contestants typically get a longer time to bake a larger dessert, which must include a new theme and/or ingredients. The lowest-ranked baker in this round is eliminated every episode except for the last one. In the finale, the remaining three or four contestants compete in a winner-take-all final round. The winner gets $25,000 and in some seasons are given a feature article in Food Network Magazine.
From season 6 onward, every season has an overarching theme that relates to the theme of each challenge. For example, season 6 featured a haunted house theme, with each challenge being associated with a different room in the house.
Host and judges
The first season was hosted by Richard Blais with chefs Carla Hall, Ron Ben-Israel, and Sherry Yard serving as judges. The second season saw Carla Hall as the only returning chef/judge. She was joined by Food Network personality Sandra Lee and Damiano Carrara to help judge, and comedian Jeff Dunham as the host. For seasons three through five, the show was hosted by John Henson. Lorraine Pascale and Zac Young joined Carla Hall as judges for the third and fourth seasons, while Katie Lee replaced Pascale for season five. For the sixth season, Henson did not return to the show (likely due to difficulties owing to the COVID-19 pandemic, which was ongoing at the time). As a result, Carla Hall served as both a judge and a host for that season; she was accompanied by Zac Young and Stephanie Boswell as judges. John Henson returned to serve as host in 2021 for season seven and Carla Hall, Zac Young and Stephanie Boswell returned as judges. This lineup remained consistent until season twelve in 2026, when Aarti Sequeira joined the judging panel, replacing Carla Hall.
