The six-part series follows sisters and business partners Sophie LaMontagne and Katherine Kallinis as they run Georgetown Cupcake in Washington, DC - a small cupcake shop that they have transformed into a sweet success. The Sisters gave up their corporate jobs and risked their life savings to follow their hearts into the kitchen, armed only with their Grandmother's recipes and their sisterly bond. Each episode will go beyond the frosting to uncover the secret of Sophie and Katherine's success and follow the challenges they face as the business rapidly expands and is poised to explode on the national scene.
