  • Line your cupcake pan with paper liners. Spoon the batter into the liners, filling each about 2/3 full. Bake for about 20-25 minutes, or until a toothpick inserted in the center comes out clean. Remove from the oven and let the cupcakes cool completely on a wire rack.

  • While the cupcakes cool, beat the butter until creamy. Mix in the peanut butter, then gradually add powdered sugar and heavy cream, alternating between them.
