Chocolate Whoopie Pies

These were my first experience at making whoopie pies, and I was so pleased by the results! The first time I made them with a seven minute frosting (as pictured), and the second time I used a marshmallow creme filling. Both are delicious: the seven minute frosting is much airier and lighter, and the marshmallow creme is for those of you that love a filling with more substance. The seven minute frosting only keeps for a few hours before separating, so be sure to make it right before you plan to serve the whoopie pies. The marshmallow creme filling doesn't seem apt to separate, and could probably be made ahead of time. The whoopie pies last at least four days in a sealed container at room temperature.

Recently, I started collecting vintage cooking items for my soon-to-open Etsy store. This is my first experience with selling items, and I am SO EXCITED about it! I will be sure to update everyone when the items are up and put a link at the top of this website. Thank you so much for all of your support! 

If you have a large cookie scoop, then by all means use that. I haven't bought one yet, so I just used a large spoon to shape the dough. 

If you are using the marshmallow creme recipe for filling, then disregard the seven minute frosting photographs below.

Whoopie Pies
from Martha Stewart

• 3 1/2 cups all-purpose flour
• 1 teaspoon salt
• 1 1/2 cups unsweetened cocoa powder
• 1 tablespoon baking soda
• 1 teaspoon baking powder
• 1 cup (2 sticks) unsalted butter, room temperature
• 2 cups sugar
• 2 large eggs
• 2 cups buttermilk, room temperature
• 2 teaspoons pure vanilla extract
• Seven Minute Frosting (recipe and ingredients below)

Directions

• Preheat oven to 400 degrees. Sift together flour, salt, cocoa powder, baking soda, and baking powder. Set aside. Line two baking pans with Silpats (French nonstick baking mats) or parchment paper. In the bowl of an electric mixer fitted with the paddle attachment, cream butter and sugar until light and fluffy. Add eggs, buttermilk, and vanilla. Beat until well combined. Slowly add dry ingredients. Mix until combined.
• Using a 1-ounce ice cream scoop, place cookies onto lined baking pans, 12 per pan. Bake for 12 minutes. Remove to a rack to cool. Repeat with remaining batter.
• Spread 2 tablespoons frosting onto each of 24 cookies. Sandwich together with remaining 24 cookies.

Seven Minute Frosting

• 3/4 cup plus 1 tablespoon sugar
• 1/3 cup water
• 1 tablespoon light corn syrup
• 3 large egg whites
• 1/4 teaspoon pure vanilla extract

Directions

• Heat 3/4 cup sugar, the water, and
  corn syrup in a medium saucepan
  over medium heat, stirring until sugar
  dissolves. Increase heat, and bring to
  a boil. Wash down sides of pan with
  a wet pastry brush to prevent sugar crystals from forming. Cook until it registers 235 degrees on a candy thermometer.
• Meanwhile, whisk whites with a
  mixer on medium speed until soft
  peaks form, about 2 1/2 minutes. Add
  remaining tablespoon sugar; reduce
  speed to medium-low. Pour sugar syrup
  into whites in a slow, steady stream.
  Increase speed to medium high; beat
  until stiff peaks form, about 7 minutes.
  Beat in vanilla; use immediately.

• 1/2 cup butter
• 1 cup confectioners' sugar
• 1 cup Marshmallow Fluff
