Whoopie Pies!

I made whoopie pies for boss's day to celebrate Julie's leadership skillz. Megan said they were her favorite thing I had made so far so I may have to make these again in the future. The only thing i did differently was to make them smaller than the recipe calls for. (I think it made around 20). The recipe is from Epicurious, and the photo is courtesy of Leggo my Meggo Lewis Photography.



INGREDIENTS:
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
1 stick (1/2 cup) unsalted butter, softened
1 cup packed brown sugar
1 large egg

For filling
1 stick (1/2 cup) unsalted butter, softened
11/4 cups confectioners sugar
2 cups marshmallow cream such as Marshmallow Fluff
1 teaspoon vanilla


Make cakes:
Preheat oven to 350°F.

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 2 buttered large baking sheets. Bake in upper and lower thirds of 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 filling on flat sides of half of cakes and top with remaining cakes.

Cooks' notes:
• Cakes can be made 3 days ahead and kept, layered between sheets of wax paper, in an airtight container at room temperature.
• Filling can be made 4 hours ahead and kept, covered, at room temperature.
