"These whoopie pies are soft, cakey cookies studded with tart, juicy blueberries and filled with tangy cream cheese frosting. I bring them to family and school events and they are always the first thing gone! Make sure to continually scrape the sides of the bowl with a spatula while making the batter and frosting. —Kathy Martino, Pittsburgh, Pennsylvania..."
