Devil's Food Cupcakes with Creamy Peanut Butter Frosting

Anyone who knows me even a little, knows how crazy I am about chocolate and peanut butter.  So it’s no surprise that these cupcakes would be in my top 5 all time favorite cupcakes in the entire world. These rich, velvety, chocolate cupcakes, filled with a creamy peanut butter buttercream and frosted with that same creamy peanut butter buttercream, really are exceptional!  In fact, they are so exceptional that heaven to me would be swimming in a pool filled with these cupcakes.


Cake recipe adapted from Rose Levy Beranbaum's Rose's Heavenly Cakes

Makes 24 cupcakes



For the Devil's Food Cake:
  • 1 ounce unsweetened chocolate (90% or higher)
  • 3/4 cup plus 1-1/2 tablespoon unsweetened cocoa powder
  • 1 cup boiling water
  • 2 large eggs
  • 2 large egg yolks
  • 1/4 cup sour cream
  • 1 teaspoon vanilla
  • 2-1/4 cups cake flour, sifted and leveled off
  • 1-1/2 cups firmly packed light brown sugar
  • 1 teaspoon baking soda
  • 1/2 tsp salt
  • 2 sticks of butter


For the Peanut Butter Filling/Frosting:

  • 1 cup (2 sticks) unsalted butter, softened
  • 1 cup peanut butter
  • 1 teaspoon vanilla extract
  • 3-1/4 cups confectioners' sugar
  • 5 tablespoons heavy cream



Step 1:  Preheat the oven to 350. Line 2 standard cupcake pans with liners.
Step 2: In a medium bowl, whisk the chocolate, cocoa, and boiling water until smooth. Cover with plastic wrap and cool for about an hour at room temperature.
Step 3: Combine  the eggs, yolks, sour cream, vanilla, and half the chocolate mixture in another bowl, just until slightly combined.
Step 4: Make the batter In the bowl of a stand mixer fitted with the flat beater, mix the flour, sugar, baking soda, and salt on low speed for 30 seconds. 
Step 5: Add the butter and the remaining chocolate mixture. Mix on low speed until the dry ingredients are moistened. Raise the speed to medium and beat for 30 seconds. Scrape down the sides of the bowl.
Step 6: Starting on medium-low speed, with the mixer off between additions, add the egg mixture in two parts. Beat on medium speed for 45 seconds after each addition to incorporate the ingredients and strengthen the structure.The batter will be slightly fluffy. Scrape down the sides of the bowl.
Step 7:   Divide batter evenly among lined cups, filing each three-quarters full. 
Step 8: Bake, rotating tins halfway through, until golden and a cake tester inserted in the centers comes out clean, about 17 to 20 minutes. Transfer tins to wire racks to cool completely before removing cupcakes. 
Step 9: For the filling/frosting: Cream Butter using a paddle attachment.
Step 10: Add the vanilla and peanut butter and beat until well mixed, light and fluffy about 4 to 5 minutes. Add confectioners' sugar a cup at a time, alternating with heavy cream. Whip on medium-high speed for 4-5 minutes until frosting is light and fluffy.
Step 11: To assemble the cupcakes: When cupcakes are cool, cut an upside down cone shape out of the top of your cupcake. Add your peanut butter filling to a pastry bag and squeeze filling in the cupcake using a plain round pastry tip.
Step 12: Frost cupcakes with creamy peanut butter frosting and sprinkle with chopped peanut butter cups, if desired.



The devil's food cupcakes with creamy peanut butter frosting are a decadent treat that will put your sweet tooth to rest for days! It would have been an amazing cupcake without the ganache. But the ganache was an unexpected present hidden in the treat and made these cupcakes soar. The peanut butter frosting is delicious..perfectly peanut buttery and deliciously sweet and fluffy.
