Ingredients
  

  • 1 cup unsalted butter 2 sticks or 227g
  • 1 cup creamy peanut butter 260g
  • 1 teaspoon vanilla
  • 4 cups sifted confectioners’ sugar 460g
  • ¼ teaspoon salt optional

Instructions
 

  • Butter an 8-inch square baking pan then line with a piece of parchment paper with the 2 sides overhanging for easy removal.
  • Put butter and peanut butter in a large bowl and microwave until both are melted and liquid, about 3 minutes. Whisk until thoroughly combined.
  • Stir in the vanilla and salt, if using.
  • Add the powdered sugar and stir until no white streaks remain.
  • Press the fudge into the prepared pan and smooth with a spatula. If you’d like a swirly pattern on top, press the edge of a spoon around the surface.
  • Let cool to room temperature then cover and refrigerate for 4 hours until set and firm.
  • Cut into squares.
  • Store in an airtight container at room temperature for a week, or 2-3 weeks in the refrigerator.

Notes

  • Use a commercial brand of peanut butter such as JIF or Skippy.
  • Don’t substitute margarine for the butter. It may not set properly or have the right texture.
  • Let come to room temperature before eating, it’s creamier.
  • I find I get a neater slice if the fudge is at a cool room temperature (after chilling and setting in the refrigerator). Clean the knife and dip the knife into hot water between each slice.
  • Have the pan buttered and lined before starting so you can get the fudge into the pan without delay. As it cools it gets harder to smooth.
