This week Todd heads to Salt Lake City to take on the sweet treat that sparked his career as a food hacker -- Mrs. Fields Famous Chocolate Chip Cookie. There's definitely something that sets this recipe apart from your mother's, and Todd is on a mission to find out what that secret something is. In his quest to unravel the cookie mystery, he seeks help from some very special, "little" chocolateers, and he even finds himself doing some undercover work as an electrician in a Mrs. Fields store. Eventually, he tries to find the woman behind the cookie (Debbie Fields), but soon realizes she is impossible to find. As a last resort, Todd uses an unconventional method to make a connection to Mrs. Fields through psychic powers. Will he successfully uncover the secrets and finally get this recipe down pat, or will it take him another 20 years to crack the cookie code?
