Nina McMullin has been baking all her life and decided to create a part-time outlet for her unique cupcakes. So she and her family set up a Thursday through Saturday business in an 1840's building adjacent to the Princeton Art Guild's historic building. Her shop, Mrs. McLovets' Cupcakes, opened in 2012, features five cupcake flavors a week. The shop's working space is 8' x 22', so this is truly a "small business."
