Ingredients

  • For the chocolate cakes:
  • 2 cups all-purpose flour
  • 2/3 cup Dutch-process cocoa
  • 1 1/4 teaspoons baking soda
  • 1 1/2 teaspoons kosher salt
  • 1 cup well-shaken buttermilk
  • 1 teaspoon vanilla extract
  • 8 tablespoons (1 stick) unsalted butter
  • 1 cup dark brown sugar
  • 1 large egg
  • For the filling:
  • 12 ounces whipping cream
  • 1 teaspoon vanilla extract
  • 4 teaspoons confectioner's sugar
  • 1 teaspoon lemon zest (from one lemon)
  • 6 ounces fresh red raspberries (about 30)

Method

  • First, prepare the cakes. Preheat oven to 350° F.
  • Whisk together flour, cocoa, baking soda, and salt.
  • In another bowl, cream together butter and sugar. When light and fluffy, add in egg.
  • Mix in 1/2 of the flour mixture into the butter mixture.
  • Add vanilla and buttermilk.
  • Combine in the rest of the flour mixture with the batter.
  • Measure out 1/4 cupfuls of batter onto two baking sheets, leaving about 2 inches around each cake. Bake for about 12 minutes, switching pan position after 6 minutes. Cakes are done when they spring back to touch. Be careful not to overbake or they'll dry out. Cool completely on baking sheets before assembling into whoopie pies.
  • While cakes are baking, prepare the filling. First, whip cream into soft peaks, then gently stir in sugar, lemon zest, and vanilla. Refrigerate until ready to assemble whoopie pies.
  • Assemble whoopie pies just before serving. Mound about 2 tablespoons of prepared cream filling onto the bottom half of a cake. Then place about 5 raspberries onto cream, and top with another cake, bottom down. There will be extra cream-- feel free to serve with another dollop on the side, if eating on a plate.
