I'm not sure, Jen. It's definitely a "regional" favorite, that's for sure. Here in Maine, they can't keep them on the shelves. They're kind of odd, I guess, not nearly as pretty or elegant as other desserts. But for some reason, they're sweeping the nation! If you followed the Wicked Whoopie Recipe, you've made a decent one. I posted some other recipes on page 3 of this thread. Give them a look over and see what you think. I hope you find a recipe you like!
