Chocolate Cupcakes:

  • 1 cup granulated sugar
  • ¾ cup plus 2 tablespoons all purpose flour
  • ¼ cup plus 2 tablespoons unsweetened cocoa powder
  • 1 teaspoon baking powder
  • ½ teaspoon baking soda
  • pinch of salt
  • 1 egg
  • ½ cup milk
  • ¼ cup vegetable or canola oil
  • 1 teaspoon pure vanilla extract
  • ½ cup boiling water
  • about 30 miniature peanut butter cups 15 left whole (for filling the cupcakes) and the other 15 coarsely chopped (for topping the cupcakes)

Peanut Butter Frosting:

  • 1 ¼ cups powdered sugar
  • 1 generous cup creamy peanut butter
  • 6 tablespoons butter softened
  • ¾ teaspoon pure vanilla extract
  • ¼ teaspoon salt
  • ¼ cup to ⅓ half and half
  • ¼ cup hot fudge sauce for drizzling (make sure it's not hot)


For the cupcakes:

  • Preheat oven to 350°F. Line 15 muffin cups with cupcake liners. Set aside.
  • Combine first 6 ingredients in a bowl. Once combined, beat in egg, milk, oil and vanilla. Beat for 2 minutes. Stir in boiling water until well combined; the batter will be thin.
  • Pour the batter into prepared cupcake liners, filling each about ⅔ full. Place one peanut butter cup in the middle of each of the cups of batter, no need to press it down, as it will sink as the cupcakes bake.
  • Bake the cupcakes for about 18 minutes, until they have puffed up slightly and the tops spring back when you touch them.
  • Cool for 15 minutes in the pan and then remove to a wire rack to cool completely.

For the frosting:

  • Beat the powdered sugar, peanut butter, butter, vanilla and salt for several minutes, until smooth. Slowly add in half and half until you reach your desired consistency.
  • Using a butter knife or a pastry bag with a piping tip, generously frost the tops of all the cupcakes. Drizzle with hot fudge sauce (not hot) and sprinkle with chopped peanut butter cups.
