With The Cookie Jar, Hannah Swensen has a mouthwatering monopoly on the bakery business of Lake Eden, Minnesota. But, when a rival store opens, tensions begin to bubble. As she sits in her nearly empty store on Groundhog Day, Hannah can only hope that spring is just around the corner, and that the popularity of the new Magnolia Blossom Bakery is just a passing fad. The southern hospitality of Lake Eden's two Georgia transplants, Shawna Lee and Vanessa Quinn, is grating on Hannah's nerves and cutting into her profits. At least, Hannah has her business partner Lisa's wedding to look forward to. Unfortunately, Shawna Lee has finagled an invitation to the reception and is bringing her Southern Peach Cobbler for the dessert table. Things go from bad to worse when Shawna Lee and Hannah's sometime-boyfriend, Detective Mike Kingston, are no-shows to the wedding. When Hannah sees lights on at the Magnolia Blossom Bakery after the reception, she investigates, and finds Shawna Lee shot to death. Everyone in town knew the Cookie Jar's business was suffering, a fact that puts Hannah at the top of the initial list of suspects. But, with a little help from her friends, Hannah's determined to track down whoever had the right ingredients to whip up a murder.
