(serves 12...big whoopie pies)
4 cups flour
1 cup cocoa (preferably Dutch processed)
2 tsp. baking soda
1 tsp. salt
2 cups packed brown sugar
2 sticks butter, softened but still cool
2 large eggs, room temp
2 tsp. vanilla
2 cups buttermilk
3 sticks butter, softened but still cool
2 1/2 cups powdered sugar
3 tsp. vanilla
1/4 tsp. salt
5 cups marshmallow creme
Directions: Heat oven to 350 degrees. In a large bowl, cream together the butter and sugar with a hand mixer...about 4 minutes. Add the egg and vanilla. In a separate bowl, mix together the dry ingredients: flour, cocoa, baking soda, and salt. Pour some of it into the butter/sugar mixture, alternating with the buttermilk..dry mix, buttermilk, dry mix, buttermilk, etc. Drop the batter onto sheet pans covered in parchment paper. Give the cookies plenty of room to spread. Bake for about 7 minutes, rotate the pan in the oven and bake for 7 minutes more OR until the cookies "spring bag" when lightly pressed with your finger.
For the filling, beat the softened butter and sugar until fluffy. Add the vanilla and salt. Beat in the marshmallow creme. Mix well. Refrigerate for about 30 minutes. Dollop on a cookie, take another cookie on top and press together until the filling spreads to the edges. Eat!
