  • 1 can vanilla frosting (16 ounces)
  • 1 jar peanut butter (crunchy or creamy) (18 ounces)


  • Empty entire jars of vanilla frosting and peanut butter into a large microwave-safe mixing bowl.
  • Place in microwave and heat for about 60 seconds or until melted. Mix well.
  • Quickly pour the mixture into a 9x9 pan lined with foil.
  • Allow fudge to set, cut into small squares, and enjoy!


  • Use creamy peanut butter, NOT natural. The natural peanut butter is too runny and will not set properly.
  • Stay away from whipped frostings. The whipped frostings are not the right consistency, and again will not allow the fudge to set properly.
  • Add any garnishes or add-ins right away before it sets or it won't stick.
  • A glass pan is easiest, but any pan lined with foil will work.
