Dark Chocolate Whoopie Pies with Nutella filling

Another nice fall day here.  I've been wanting to try making whoopie pies for a long time and even purchased one pan specifically made for making them.  That was a waste of money.  After one pan, I went back to my standard parchment lined baking sheets.  The cookie part is good but the filling is excellent and I'll be using that recipe for more than just this recipe.

Dark chocolate whoopie pies

1 stick butter (no substitutes), softened
1 cup sugar
1 large egg
1 cup buttermilk
1 tsp vanilla
2 cups flour
1/2 cup dark cocoa
1 tsp salt
1 1/4 tsp  baking soda

1/2 cup whipping cream
1/2 cup mascarpone cheese
1/2 cup Nutella

Cream sugar and butter.  Add in egg, vanilla and buttermilk.  Gradually add in dry ingredients.

Using a medium scoop, put on parchment lined cookie sheets leaving plenty of room between scoops.

Bake until when you finger test and it doesn't leave an indent.

Let cool completely.

Whip cream until soft peaks form.  Add in mascarpone and Nutella.  Spread a level amount between cookies.

Servings: 18

Bake at 325°F
