Method
Whoopie Pie Shells
- Preheat oven to 350.
- In a large bowl, sift together the flour, cocoa powder, salt, and baking soda. Set aside.
- In a separate bowl, combine the butter, sugar, shortening, eggs, and vanilla extract with a hand or stand mixer.
- Add the hot water and sour milk to the butter mixture, and combine well.
- In stages, add the bowl of dry ingredients to the wet bowl, mixing well after each addition.
- Line a baking sheet with parchment paper. Drop about 3 tablespoons of batter onto the sheet, leaving 2" of space between each shell.
- Bake 10 minutes, and allow to cool several minutes on the sheet before removing to a rack to finish cooling.
Whoopie Pie Filling
- Sift the confectioner's sugar into a large bowl.
- Add all the remaining filling ingredients and mix on medium high until well combined and slightly fluffy.
- Scoop the desired amount onto an upturned chocolate shell, and lightly press a second shell on top.
