Let’s face it, the chocolate whoopie pie is officially a classic American dessert. I am the first person to admit that the term “classic” is overused, abused, and on the verge of becoming meaningless; however, it would be a travesty not to give this dessert its due. The whoopie pie, essentially two cake-like cookies with a generous helping of a creamy filling sandwiched between them, has its roots in the Northeast. Pennsylvanians will tell you they originated in Pennsylvania Dutch country, and the people of Maine will argue that it comes from their state. This version features a very moist, deep-chocolate cookie and a light and fluffy vanilla filling (for good measure, we also provide an option for a peanut butter filling). Enjoy—and spread the whoopie religion. It can become as ubiquitous as the chocolate chip cookie and the all-American brownie with a little help from you.
