Ingredients

Units Scale

For the Cupcakes:

  • 1 box chocolate cake mix (plus ingredients called for on the box)
  • 12 mini peanut butter cups (unwrapped)

For the Peanut Butter Frosting:

  • 1/2 cup unsalted butter (softened)
  • 1/2 cup creamy peanut butter
  • 2 cups powdered sugar
  • 23 tablespoons heavy cream or milk
  • 1/2 teaspoon vanilla extract

For Garnish (optional):

  • Mini peanut butter cups or chocolate drizzle

Instructions

  1. Prepare the Cupcakes: Preheat the oven to 350°F (175°C) and line a 12-cup muffin pan with paper liners. Prepare the chocolate cake batter according to the package instructions. Fill each cupcake liner about 2/3 full with batter, then gently press a mini peanut butter cup into the center of each one (do not push all the way to the bottom). Bake for 18–22 minutes or until the tops spring back when touched. Let cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
  2. Make the Frosting: Beat together the butter and peanut butter until smooth and creamy. Gradually add the powdered sugar, beating on low speed. Add the vanilla extract and just enough heavy cream or milk to reach your desired consistency. Beat until light and fluffy. Pipe or spread the frosting onto cooled cupcakes. Garnish with additional mini peanut butter cups or a drizzle of melted chocolate if desired.

Notes

  • To make them extra indulgent, freeze the peanut butter cups before baking to help them hold their shape.
  • These cupcakes also freeze well, unfrosted, for up to 2 months.
