Peanut Butter Chocolate Cupcakes

These cupcakes taste better than a Reese’s Cup if that is possible!

These cupcakes taste better than a Reese’s Cup if that is possible. I sent some home with a friend yesterday and today all she could say about them was “OMG”. This peanut butter buttcream is the stuff dreams are made of if you are a peanut butter lover. I seem to be on a peanut butter and chocolate kick lately, last week it was a peanut butter chocolate cream pie. Do you have any idea how hard it is to be on a diet and do food blogging? I try to send as much of it away as I can.

When you are ready to coat the cupcakes with the chocolate, make sure you put the chocolate into a bowl that is deep enough to dip the cupcakes in. Make sure you chocolate is not too hot or it will melt the buttercream. It should be around 80 degrees more or less.

  • Cake
  • 1/2 cup cocoa
  • 1 oz. unsweetened chocolate
  • 1 cup boiling water
  • 1 3/4 cups plus 2 tablespoons cake flour
  • 1/2 teaspoon salt
  • 1 teaspoon baking soda
  • 1 1/2 cups brown sugar
  • 1 cup butter
  • 1/4 cup sour cream
  • 2 eggs
  • 2 egg yolks
  • Peanut Butter Buttercream
  • 1/2 cup granulated sugar
  • 2 large egg whites
  • 1/8 teaspoon salt
  • 12 tablespoons softened unsalted butter, cut into 1/2-inch pieces
  • 1 cup peanut butter
  • 2 teaspoons pure vanilla extract
  • Chocolate Topping
  • 8 oz. semi-sweet chocolate
  • 2 tablespoons vegetable oil
  1. To make the cake:
  2. Preheat oven to 350 degrees. Add cocoa and unsweetened cocoa to boiling water, stir to disolve. Set aside to cool completely. You can put it in the refrigerator but stir it a couple of times.
  3. Mix together flour, salt, baking powder and brown sugar in your mixing bowl. Add the butter and beat until it resembles dough. Add the cooled chocolate mixture and blend it until mixed thoroughly.
  4. Mix together the eggs and sour cream. Add it slowly to the dough mix, then mix for about 2 minutes until it is light and fluffy.
  5. Bake for 18 -20 minutes. While cupcakes are cooling, prepare the buttercream.
  6. Peanut Butter Frosting
  7. In bowl of standing mixer, whisk sugar, egg whites, and salt until combined. Set bowl over pan of simmering water and gently whisk until mixture registers 160 degrees F on instant read thermometer. Immediately transfer to mixer fitted with whisk attachment. Whip on medium-high speed until mixture is just cool. On medium speed, whip in butter, one piece at a time, until combined and creamy. Add peanut butter and vanilla and beat until smooth. Pipe buttercream on top of cupcakes. Place in refrigerator for 1 hour.
  8. To prepare the chocolate topping:
  9. Melt chocolate with oil over a double boiler over very low heat. Dip cupcakes into chocolate and set aside to harden.
  10. Pipe about 1/3 cup frosting onto each cupcake. Chill cupcakes in fridge until buttercream is completely firm, about 1 hour.

    recipe sounds good but is very confusing. When and where does the cooled cocoa and chocolate get added to the batter. In your directions you wrote “add cocoa and unsweetened cocoa to boiling water. The last direction is to pipe frosting on each cupcake. Does that mean that you frost the cupcake, refrigerate one hour, dip them into the chocolate, harden and pipe frosting again?

      @rivky, fixed the recipe, the chocolate mixture goes in before the eggs and sour cream.
      Two, after you pipe the buttercream on the cupcakes refrigerate the cupcakes for one hour before dipping them in the chocolate topping. Sorry for the confusion.
