  • Cupcake Liners
  • Cupcake Baking Tin
  • Mixing Bowl
  • Medium Bowl
  • Electric Mixer
  • Small Saucepan



  • 16 miniature peanut butter cups
  • 1 box Duncan Hines® Milk Chocolate Premium Brownie Mix
  • 3 large eggs
  • ¼ cup water
  • ½ cup oil


  • ½ cup creamy peanut butter
  • ¼ cup butter softened
  • 2 cups powdered sugar sifted
  • 3 Tablespoons milk
  • ½ teaspoon pure vanilla
  • teaspoon salt


  • 14 miniature peanut butter cups


  • 4 ounces bitter sweet chocolate chopped into very small pieces
  • ½ cup heavy whipping cream
  • 2 Tablespoons honey
  • 2 Tablespoons light corn syrup
  • 2 Tablespoons vanilla


  • Preheat oven to 350°F. Place paper baking cups in each of 12 regular-size muffin cups. Remove foil and cups from candy pieces. Set aside.
  • Prepare brownie mix as described on box to make cakey brownies using the eggs, water and oil. Fill each up about 2/3 full with batter. Place 1 unwrapped candy piece, upside down, on top of batter in each cup. Lightly tap piece down into batter.
  • Bake 23 to 25 minutes or until toothpick inserted in center of cup comes out almost clean. Cool 5 minutes; remove from pan. Place on wire rack; cool completely.
  • Make icing by placing peanut butter and butter into medium bowl. Beat with an electric mixer on medium speed until light and creamy; scrape bowl. Add powdered sugar, milk, vanilla and salt. Beat on low speed 1 minute; scrape bowl. Beat on medium speed until smooth and creamy. Spread about 2 tablespoons of icing on each cupcake leaving the edge un-iced.
  • Prepare ganache: in a small saucepan over medium heat, warm the heavy cream until very hot, but not boiling. Place chocolate pieces in a heat safe bowl. Pour the hot cream over the chocolate and allow it to sit for about 5 minutes. Whisk the cream and chocolate until smooth and thoroughly combined. -Whisk in the honey, corn syrup, and vanilla. Allow to cool for about 15 minutes. Do not let the glaze sit for too long or it will harden up before you spoon it over the frosting. Spoon the glaze on the tops of the frosted cupcakes, allowing it to drip down the sides a little bit. Don't add too much glaze or it will drip all over your liners.
  • Top each cupcake with a peanut butter cup. Store cupcakes in the refrigerator. Remove them to room temperature one hour before serving.


For this recipe, I doubled the frosting, given in the instructions and ingredients. I love to generously add a lot of frosting to my cupcakes, because let’s be honest, that’s the best part.
You don’t have to double the frosting recipe, but we highly recommend it. These are so yummy with a good portion of the fudgy peanut butter frosting on top.
