Ingredients

  • 1 1/4 cups all-purpose flour
  • 3/4 cup unsweetened cocoa
  • 1 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 1/2 cups sugar
  • 1 1/2 sticks unsalted butter, room temperature
  • 1 large egg
  • 1/2 stick unsalted butter, at room temperature
  • 1/4 cup vegetable shortening (recommended: Crisco)
  • 3 teaspoons vanilla extract
  • 2 cups powdered sugar, sifted

Method

  • In a mixing bowl, using an electric mixer, on low speed, thoroughly combine all of the dry ingredients.
  • Add the butter and the egg.
  • Mix until the dough comes together in a nice ball.
  • Form the dough into 24 balls.
  • Preheat the oven to 350 degrees F.
  • Put the balls on cookie sheets that have either been lined with parchment paper or slightly (very slightly) greased with butter.
  • Gently press the balls with your thumb, ever so slightly, squishing the ball.
  • If you are not using parchment paper, lift the balls from the sheet and then put them back, this will avoid sticking later on.
  • Bake for 8 to10 minutes, checking the cookies periodically.
  • You can rotate the cookie sheets after 4 minutes to ensure that the cookies are baking evenly.
  • Remove the pans from the oven and put the cookies on a cooling rack or a clean surface.
  • Allow them to cool at least 15 minutes.
  • Filling: Put the butter, shortening, and vanilla into a bowl, and mix with an electric mixer on low speed.
  • Gradually add the powdered sugar and mix until the filling is light and fluffy.
  • When the cookies are cool, smear a small amount of the filling on 1 side of half of the cookies.
  • Top with the remaining cookies, creating that famous whoopee-pie look.
  • Refrigerate the cookies for about 20 minutes before serving.
  • Cook's Note: Dip the cookies in a cool glass of milk, if desired.
  • To add a touch of elegance to this dessert, try infusing milk with lavender.
  • Add a little milk, 1 tablespoon of honey, and a little crushed lavender to a blender.
  • Blend on high for about 3 minutes.
  • Refrigerate for about 20 minutes, then stir with a spoon and serve!
