  • 2 cups sugar
  • ½ cup milk
  • 1 tsp vanilla extract
  • ¾ cup peanut butter



  • Prepare an 8X8 (or 9X9) square pan with buttered foil. To do this, cut apiece of foil that is slightly larger than the pan and then spread softened butter on the foil with a spatula or by placing your hand in a plastic bag like a glove and using your fingers to spread the butter on the foil. Press the foil into the pan, butter side up. The foil should come at least most of the way up the sides.

Making the Fudge

  • Next, in a medium saucepan, bring the sugar and milk to a boil over medium heat, stirring occasionally. Boil for 2 1/2 minutes.
  • After the 2 1/2 minutes, remove the mixture from heat and add the peanut butter and vanilla extract, stirring until smooth.

Set and serve

  • Proceed to pour the fudge mixture into prepared pan and let set for about1-2 hours in the refrigerator before slicing and serving.
  • To slice, just remove the entire foil from the pan and fold the edges down flat. It is so much easier to slice and serve this way than trying to do it while it is still in the pan!
  • Serve and enjoy!
