Chocolate Ganache Peanut Butter Cupcakes

I've been baking cakes for years and enjoy trying new combinations of flavors and textures. For this peanut butter cupcake recipe, I blended peanut butter and chocolate. As soon as I took the first bite, I knew I had created something divine! —Ronda Schabes, Vicksburg, Michigan
  • Total Time
    Prep: 55 min. Bake: 20 min. + cooling
  • Makes
    2 dozen


  • 2 cups sugar
  • 1-3/4 cups all-purpose flour
  • 3/4 cup baking cocoa
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon baking powder
  • 1 cup buttermilk
  • 1 cup strong brewed coffee, room temperature
  • 1/2 cup canola oil
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1/2 cup creamy peanut butter
  • 3 tablespoons unsalted butter, softened
  • 1 cup confectioners' sugar
  • 2 to 4 tablespoons 2% milk
  • 2 cups semisweet chocolate chips
  • 1/2 cup heavy whipping cream
  • 1 cup packed brown sugar
  • 4 large egg whites
  • 1/4 teaspoon salt
  • 1/4 teaspoon cream of tartar
  • 1 teaspoon vanilla extract
  • 2 cups unsalted butter, softened
  • 1/3 cup creamy peanut butter
  • Chocolate curls, optional


  • Preheat oven to 350°. In a large bowl, combine first 6 ingredients. Whisk buttermilk, coffee, oil, eggs and vanilla until blended; add to the dry ingredients until combined. (Batter will be very thin.) Fill paper-lined muffin cups two-thirds full.
  • Bake 18-20 minutes or until a toothpick inserted in the center comes out clean. Cool 10 minutes before removing from pans to wire racks to cool completely.
  • In a small bowl, cream peanut butter, butter, confectioners' sugar and enough milk to achieve piping consistency. Cut a small hole in the corner of a pastry bag; insert a small round tip. Fill with peanut butter filling. Insert tip into the top center of each cupcake; pipe about 1 tablespoon filling into each.
  • Place chocolate chips in a small bowl. In a small saucepan, bring cream just to a boil. Pour over chocolate; whisk until smooth. Dip the top of each cupcake into ganache; place on wire racks to set.
  • In a large heavy saucepan, combine brown sugar, egg whites, salt and cream of tartar over low heat. With a hand mixer, beat on low speed 1 minute. Continue beating on low over low heat until frosting reaches 160°, 8-10 minutes. Pour into a large bowl; add vanilla. Beat on high until stiff peaks form, about 5 minutes.
  • Add butter, 1 tablespoon at a time, beating well after each addition. If mixture begins to look curdled, place frosting bowl in another bowl filled with hot water for a few seconds. Continue adding butter and beating until smooth. Beat in peanut butter 1-2 minutes or until smooth.
  • Place frosting in a pastry bag with large star tip; pipe onto each cupcake. If desired, top with chocolate curls. Store in an airtight container in the refrigerator. Let stand at room temperature before serving.

Test Kitchen Tips
  • Dark brown sugar contains more molasses than light or golden brown sugar. The types are generally interchangeable in recipes. But if you prefer a bolder flavor, choose dark brown sugar.
  • Canola oil is high in monounsaturated fat, a type that helps to decrease blood cholesterol levels, and low in saturated fat, which can increase blood cholesterol. Olive oil would also taste great in this recipe and has the same healthy-fat properties.

      As a novice baker I had so much fun baking these! The only thing I struggled with was the icing. The egg whites were stiff peaks but as soon as I started adding the butter, it all went flat. Could you please advise what I can do next time to correct this because they are the best things I have ever baked! Thank you ??

      Made these for a couple of special events (boss's birthday, Son's birthday at hospital where he works). Well received and, according to my son, still talked about. First time making them seemed challenging. Definitely got easier more time made them. In fact, son turns 30 tomorrow, Making them again!!

      Cupcakes are delicious- my only issue was the buttercream - it seemed burnt at the bottom - next time I may try in a bowl over the pot instead

      I made these to break in my new stand mixer. I can't possibly thank you enough of gush over them enough! The sponge was perfection. The filling divine. I did use a different PB Buttercream, but only bc I didn't want a cooked frosting. So my rating is for the cake, filling, and ganache. My new go-to!

      I substituted a brown sugar/peanut butter icing that did not require cooking, but that was just my preference. I have had two people tell me "these are the best cupcakes I have ever eaten". I tend to agree!

      How much peanut butter do you add for frosting? This doesn't have peanut butter in ingredients but says "peanut butter frosting".
