Chocolatey whoopie pies with marshmallow filling

Whoopie Pies are a trend that has gone completely past me. While I'm still swimming on the cupcake wave, first came the cake pops and finally the whoopie pies. Both are actually rather suspicious to me. Are Whoopie Pies maybe out again? As always, I jump on the train relatively late. As they are apparently still on everyone's lips, I had to go now and bake Whoopie Pies myself. Otherwise I can not have a say anyway. They are supposed to be very similar to cupcakes, only in biscuit look and with the frosting in the middle.
Well, I'm always open to new things (even though it's not that new anymore) and try it So, to whoopie pies.
I'm looking for classic recipes and find a kind of standard recipe in various variations of dark chocolate sauce with a fluffy marshmallow filling.
The recipe reminds me very much of my (or Marthas ...) chocolate cupcakes with marshmallow frosting and filling. So I change it to my own taste and go.
Perfect, so let's start the direct comparison between Whoopie Pies and Cupcakes.
