Host Carla Hall gives the nine bakers their Mid-Atlantic-themed master challenge: making their own upscale version of Maryland's Smith Island cake that incorporates a classic Maryland ingredient, boardwalk popcorn. In the bake-off round, the least successful bakers must make a dessert inspired by the Pennsylvania classic shoofly pie. Carla and judges Gesine Prado and Jason Smith eliminate one baker from the competition.

The seven bakers left in the competition are tasked with putting their own spin on kuchen, the official state dessert of South Dakota. The featured flavor is cookies, and they have to serve their kuchen with a side of ice cream. The competitors in the bake-off challenge must do a switcheroo with Minnesota's scotcheroo bar, making a new dessert using its classic ingredients of chocolate, peanut butter, rice cereal and butterscotch. Host Carla Hall and judges Gesine Prado and Jason Smith decide which baker to send home.
