Devil’s Food Whoopie Pies

"These mini cookie cakes were one of my favourite treats while I was growing up in Pennsylvania. We called them gobs because they are gobs of fun to eat! The recipe can make fewer or more, depending on how large or small you make the cookies. Place the finished chocolate whoopie pies in large cupcake liners for a professional look." —Pamela Esposito, Galloway, New Jersey
