Whoopie Pie Shells
  1. Preheat oven to 350.

  3. In a separate bowl, combine the butter, sugar, shortening, eggs, and vanilla extract with a hand or stand mixer. 
  4. Add the hot water and sour milk to the butter mixture, and combine well. 
  5. In stages, add the bowl of dry ingredients to the wet bowl, mixing well after each addition. 
  6. Line a baking sheet with parchment paper. Drop about 3 tablespoons of batter onto the sheet, leaving 2" of space between each shell. 
  7. Bake 10 minutes, and allow to cool several minutes on the sheet before removing to a rack to finish cooling.
Whoopie Pie Filling
  1. Sift the confectioner's sugar into a large bowl.
  2. Add all the remaining filling ingredients and mix on medium high until well combined and slightly fluffy. 
  3. Scoop the desired amount onto an upturned chocolate shell, and lightly press a second shell on top.
