  • 1/2 teaspoon salt
  • 1/2 cup (1 stick) unsalted butter, softened
  • 1/2 cup creamy peanut butter
  • 1 cup granulated sugar

  • 3 cups powdered sugar

Instructions

  4. Beat in the eggs one at a time, then stir in the vanilla extract.
  5. Gradually add the dry ingredients to the wet ingredients, alternating with the milk, beginning and ending with the dry ingredients. Mix until just combined.
  6. Divide the batter evenly among the prepared muffin cups, filling each about two-thirds full.
  7. Bake for 18-22 minutes, or until a wooden skewer inserted into the center comes out clean.
  8. Let the cupcakes cool in the pan for a few minutes before transferring them to a wire rack to cool completely.
  9. To make the frosting: In a large bowl, beat the softened butter and peanut butter until smooth.
  10. Gradually add the powdered sugar, alternating with the milk, until the frosting is smooth and creamy. Stir in the vanilla extract.

Notes

  • Ensure all ingredients are at room temperature for best results.
  • Do not overmix the batter, as this can lead to dry cupcakes.
  • Store cupcakes in an airtight container at room temperature for up to 3 days.
