Equipment

  • 8x8 inch baking pan
  • Parchment paper
  • Microwave-safe bowl
  • Rubber spatula
  • Measuring cups and spoons
  • Plastic Wrap (optional)
  • Knife

Ingredients
  

  • 16 ounces creamy peanut butter 1 jar
  • 14 ounces sweetened condensed milk 1 can
  • 1 teaspoon vanilla extract

Instructions
 

  • Line an 8x8 inch baking pan with parchment paper, leaving an overhang on the sides.
  • In a microwave-safe bowl, combine the peanut butter, sweetened condensed milk, and vanilla extract.
  • Microwave on high for 1 minute. Stir well.
  • Microwave for another 30 seconds and stir again. Continue microwaving in 15-second intervals, stirring in between, until the mixture is smooth and melted. Be careful not to overheat it.
  • Pour the melted fudge mixture into the prepared pan. Use a rubber spatula to spread it evenly.
  • Cover the pan with plastic wrap or another piece of parchment paper.
  • Refrigerate for at least 2 hours, or preferably overnight, to allow the fudge to set completely.
  • Once the fudge is firm, lift it out of the pan using the parchment paper overhang.
  • Cut into squares and enjoy.

Notes

For best results, use a mainstream creamy peanut butter like Jif or Skippy. If using natural peanut butter, the fudge may be drier; add 1-2 tablespoons of milk to compensate. Store the fudge in an airtight container in the refrigerator for up to a week, or in the freezer for up to a month. To customize, add 1/2 cup of melted chocolate chips, sprinkle chopped peanut butter cups or sea salt on top before chilling, or swirl in caramel.
