Ingredients

  • 2 cups all-purpose flour
  • 3/4 cup dark cocoa, such as Hershey's Special
  • 1 teaspoon baking soda
  • 3/4 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 1/2 sticks unsalted butter, at room temperature
  • 2 cups granulated sugar
  • 3 eggs, at room temperature
  • 1 teaspoon vanilla extract
  • 1 1/2 cups whole milk
  • One 32-ounce bag mini chocolate chips, for garnish
  • 8 ounces bittersweet chocolate (60-percent cocao), coarsely chopped, such as Ghirardelli
  • 2/3 cup plus 1/4 cup heavy cream
  • 2 1/2 tablespoons unsalted butter
  • One 8-ounce package cream cheese, at room temperature
  • 1 cup peanut butter
  • 4 cups powdered sugar

Method

  • Preheat the oven to 350 degrees F. Line cupcake pans with 18 liners.
  • In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder and salt.
  • Using an electric mixer with the paddle attachment, cream the butter until smooth.
  • Gradually add the granulated sugar about 1/4 cup at a time until the mixture is light and fluffy, scraping down the sides of the bowl occasionally.
  • Add the eggs, one at a time, beating well after each addition.
  • Add the vanilla.
  • Alternately add the flour mixture and the milk, starting and ending with the flour mixture, beating well after each addition and scraping down the sides of the bowl occasionally.
  • Spoon the batter into the liners.
  • Bake until a toothpick inserted in the center comes out clean, 16 to 18 minutes.
  • Cool the cupcakes completely.
  • Make a hole in the center of each cupcake using a small paring knife or apple corer, making sure not to go all the way to the bottom.
  • Pipe the Dark Chocolate Filling into each cupcake all the way to the top, reserving some for garnish.
  • Frost the cupcakes with Peanut Butter Frosting, reserving some for garnish.
  • Roll the edges of the cupcakes in mini chocolate chips.
  • Drizzle the cupcakes with the remaining chocolate filling, and then with the remaining peanut butter frosting.
  • Place the chopped chocolate in a small bowl.
  • In a small saucepan, heat the heavy cream over low heat until it simmers.
  • Remove from the heat and pour over the chocolate pieces.
  • Add the butter and let stand for 1 minute.
  • Stir until smooth.
  • Let cool slightly.
  • Cut 1/8-inch off the end of a piping bag.
  • Pour the mixture into the piping bag.
  • In a large mixing bowl, using an electric mixer with paddle attachment, whip the cream cheese on high speed about 30 seconds until smooth.
  • Add the peanut butter and continue mixing on high speed for 1 minute until well blended, scraping down the sides often.
  • Add the vanilla.
  • On low speed, add the powdered sugar 1/2 cup at a time.
