Amish Whoopie Pies

I made these tonight. Somewhere I saw that they can be frozen so I am freezing them on a tray until frozen and will keep in a ziploc bag......Tasted good!


For Cakes:
2 cups all-purpose flour
1/2 cup Dutch-process cocoa powder
1 1/4 teaspoons baking soda
1 teaspoon salt
1 cup well-shaken buttermilk
1 teaspoon vanilla etract
1/2 cup (1 stick/4 oz./113g) unsalted butter, softened
1 cup packed brown sugar
1 large egg

For Filling:
1/2 cup (1 stick/4 oz./113g) unsalted butter, softened
1 1/4 cups confectioners' sugar
2 cups marshmallow cream, such as Marshmallow Fluff
1 teaspoon vanilla extract

Make Cakes:
Preheat oven to 350°F/180°C. Lightly butter two large baking sheets.

Whisk together flour, cocoa, baking soda, and salt in a bowl until combined. Stir together buttermilk and vanilla in a small bowl.

Beat together butter and brown sugar in a large bowl with an electric mixer at medium-high speed until pale and fluffy, about 3 minutes in a standing mixer or 5 minutes with a handheld, then add egg, beating until combined well. Reduce speed to low and alternately mix in flour mixture and buttermilk in batches, beginning and ending with flour, scraping down side of bowl occasionally, and mixing until smooth.

Spoon 1/4-cup mounds of batter about 2 inches apart onto prepared baking sheets. Bake in upper and lower thirds of preheated oven, switching position of sheets halfway through baking, until tops are puffed and cakes spring back when touched, 11 to 13 minutes. Transfer with a metal spatula to a rack to cool completely.

Make Filling:
Beat together butter, confectioners sugar, marshmallow, and vanilla in a bowl with electric mixer at medium speed until smooth, about 3 minutes.

Assemble Pies:
Spread a rounded tablespoon of filling on flat sides of half of cakes and top with remaining cakes.
