There are few things that are more summery than s'mores.
These S'mores Whoopie Pies are an easy dessert that brings the s'mores indoors. These whoopie pies start with graham cracker cookies and sandwich marshmallow and chocolate in the middle.
Rather than using graham flour for the cookies, which can be quite hard to find, the cookies have a mix of whole wheat flour, all-purpose flour, and wheat germ. The combination of the three gives the cookies the flavor and texture of a nice, soft graham cracker.
I like to use marshmallow fluff for these whoopie pies, but it is pretty messy. If you prefer a neater s'more (are neat s'mores even a thing?), feel free to use a marshmallow in the middle instead.
