Chocolate whoopie pies with salty peanut butter filling

I decided to make another recipe out of my Whoopie Pies book.  I wanted to something sweet and salty, so I combined the chocolate whoopie pie with the salty peanut butter filling.  I removed the salt from the filling recipe so it wouldn't be quite so salty, but the filling certainly lives up to its name! 

Also, the cake isn't very sweet, so I'm calling it a fail.  I followed the recipe exactly and didn't forget any ingredients, so I'm not sure where the train fell off the track, but it still tastes better than carrots.

And they look cute :)
