For an even richer chocolate flavor, try using dark cocoa powder. If you don't have peanut butter, almond butter or even Nutella can be used for a delightful variation. Store assembled whoopie pies in an airtight container in the refrigerator to keep the frosting firm and prevent the cookies from drying out. For a fun twist, roll the edges of the frosted whoopie pies in sprinkles or chopped nuts.
