whoopie pie pattern

Ive just put a new pattern on - see below for a whoopie pie. Hope someone can make use of it. The two halves are knitted with dpns and the cream is made using i-cord technique. I read somewhere that the whoopie pie got its name for Amish men shouting "whoopie" when they found the delicious treat in their lunch box.......dont know if that's true or not, you can correct me if I'm wrong. Better get back to my city and guild stuff now - I'm doing felting and I'm relatively new to this craft, so lots of research and googling required,
Bye, Ali.
