Ingredients 

For the cupcakes:

  • 1 2/3 cups all-purpose flour
  • ¾ cup unsweetened cocoa powder
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup sour cream
  • 2 tablespoon milk
  • 1 teaspoon vanilla
  • 8 tablespoon unsalted butter, at room temperature
  • 1 ½ cups sugar
  • 2 eggs

For the filling:

  • 1 cup confectioners’ sugar
  • ¾ cup creamy peanut butter
  • 4 tablespoons unsalted butter, at room temperature
  • ½ teaspoons vanilla extract

For the frosting:

  • 3 cups confectioners’ sugar
  • 16 ounces cream cheese, at room temperature
  • 16 tablespoons unsalted butter, at room temperature (2 sticks)
  • 1 cup creamy peanut butter

Instructions

  • Preheat the oven to 350 degrees. Line two cupcake pans with paper liners.
  • To make the cupcake batter, combine the flour, cocoa powder, baking soda and salt in a medium bowl. Whisk and set aside. In a liquid measuring cup, combine the sour cream, milk and vanilla extract. In the bowl of an electric mixer fitted with the paddle attachment, cream the butter and sugar together until light and fluffy. Beat in the eggs one at a time, scraping down the bowl as needed. With the mixer on low speed, alternately add the dry ingredients and the sour cream mixture, beginning and ending with the dry ingredients. Mix just until incorporated. Set aside.
  • To make the filling, combine the confectioners’ sugar, peanut butter, butter and vanilla extract in a bowl. Beat with an electric mixer on medium speed until smooth. Using your hands, roll the mixture into 1-inch balls (at least 20).
  • Spoon one or two tablespoons of the batter into the bottom of each cupcake liner. Place a ball of the peanut butter filling in each cupcake liner and top with the remaining batter so that all the cups are filled. Bake for 18 to 22 minutes, or until a toothpick inserted in the center comes out clean. Allow to cool in the pan for 5 to 10 minutes, and then transfer to a wire rack to cool completely.
  • To make the frosting, in the bowl of an electric mixer fitted with the paddle attachment, combine the confectioners’ sugar, cream cheese, butter and peanut butter until smooth. Beat mixture until smooth and well blended. Pipe as desired onto each cupcake.
  • Store the cupcakes at room temperature for up to 2 hours, or store in the refrigerator until ready to serve.

Notes

INGREDIENT NOTES:
  • Peanut Butter: Use creamy peanut butter for the best texture.
  • Cocoa Powder: Standard unsweetened cocoa powder works great. If you use dark cocoa powder, it may change the flavor of the cupcakes as it creates a richer flavor and darker color.
  • Sour Cream: You can use Greek yogurt instead of sour cream.
OTHER
  • We use a large closed star tip for piping frosting onto cupcakes.
  • Store the cupcakes at room temperature for up to 2 hours, or store in the refrigerator until ready to serve. Remove from the refrigerator at least 30 minutes before serving to allow them to come to room temperature.
This recipe makes about 22 to 24 standard size cupcakes.
