In Honor of the Super Bowl: Whoopie Pies

I noticed on facebook that one of my friends bakes three kinds of whoopie pies for a superbowl party. For the most part I've stuck to the basic recipe (although I did make gingerbread whoopie pies with lemon icing, which were amazing). Seeing all these different kinds on one plate, however, made me think about the other possibilities. In addition to red velvet and pumpkin whoopie pies, there are other variations such as boston cream, creamsicle, and chocolate with walnut coconut filling.
