Maine Whoopie Pie Festival in Dover-Foxcroft
The Maine Whoopie Pie Festival is a one-day summer festival held at the Piscataquis Valley Fairgrounds in Dover-Foxcroft, Maine, celebrating the whoopie pie, Maine's official state treat. Running since 2009, it is produced by the Center Theatre with support from the Piscataquis Chamber of Commerce and has grown into the largest annual event in Piscataquis County.
The whoopie pie, two soft rounds of cake with a creamy filling between them, has been claimed by Maine, Pennsylvania, Massachusetts, New Hampshire, and Virginia as a regional invention, and the argument has never fully resolved.
