Preparations are underway for Lake Eden, Minnesota's annual Winter Carnival--and Hannah Swensen is set to bake up a storm at The Cookie Jar. Too bad the honor of creating the official Winter Carnival cake went to famous lifestyle maven Connie Mac--a half-baked idea, in Hannah's opinion. She suspects Connie Mac is a lot like the confections she whips up on her cooking show--sweet, light, and scrumptious-looking, but likely to leave a bitter taste in your mouth.

Hannah's suspicions are confirmed when Connie Mac's limo rolls into town. Turns out America's "Cooking Sweetheart" is bossy, bad-tempered, and downright domineering. Things finally boil over when Hannah arrives at The Cookie Jar to find the Winter Carnival cake burnt to a crisp--and Connie Mac lying dead in her pantry, struck down while eating one of Hannah's famous blueberry muffins. With the crime scene off-limits, Hannah's only alternative is to cook up a plan to save her business--by finding the killer herself . . .
