Six self-taught baking teams arrive at the Crime Scene Kitchen to start their hunt for clues, leading them to the mystery dessert. The teams with the best crime-solving technique advance to the next week, and the duo with the poorest performance of the night heads home.

Teams: Tarsha and Kristy – Torre and Michelle – Donovan and Dayveon – T and Fadi – Kathleen and Hannah – Steph and Cherry.

The self-taught bakers are back in the kitchen to investigate a twist on an all-time favorite sweet treat during the safety bake round. Then, in the elimination round, the remaining bakers must figure out the correct dessert to make in order to avoid elimination.

The self-taught bakers have one last chance to prove themselves before merging with the classically trained bakers. TV personality Nene Leakes joins the judges as the contestants are faced with their toughest challenge yet, with an extra clue in the elimination round that has the potential to throw off their investigation.

For the first time ever, the classically-trained bakers go head to head against the remaining self-taught teams, trying to crack the safety bake dessert set by guest judge Martina McBride. Then, the teams must use their detective and math skills when they compete during the elimination round.

The remaining teams of classically-trained and self taught bakers continue to battle for a spot in the semifinals. During the safety round, Yolanda and Curtis are left in the dark about the mystery dessert, piecing together the clues alongside the contestants. Then, in the elimination round, the teams must construct their most complicated cake yet, chosen by guest judge Chef Richard Blais.

With only four teams of classically trained and self-taught bakers left, the semifinalists take on the safety bake round, inspired by guest judge Dwight Howard's favorite dessert.
