Make rich, melt-in-your-mouth peanut butter fudge using only four simple ingredients. This no-bake recipe delivers classic, old-fashioned flavor without needing a candy thermometer. It sets up perfectly every time for a quick, satisfying sweet treat.

Ingredients

Scale
  • 1 (14 ounce) can sweetened condensed milk
  • 1 cup creamy peanut butter
  • 1 teaspoon vanilla extract
  • 3 cups powdered sugar

Instructions

  1. Line an 8×8 inch baking pan with parchment paper, leaving an overhang on the sides for easy removal. Lightly grease the paper.
  2. In a large microwave-safe bowl, combine the sweetened condensed milk and peanut butter. Microwave on high for 60 seconds. Stir well until the mixture is smooth and fully combined.
  3. Stir in the vanilla extract until mixed in.
  4. Gradually add the powdered sugar, about one cup at a time, mixing thoroughly after each addition until the mixture is thick and uniform. This will require some effort.
  5. Press the fudge mixture evenly into the prepared baking pan. Use a spatula or the back of a spoon to smooth the top.
  6. Refrigerate the fudge for at least 2 hours, or until firm enough to cut.
  7. Use the parchment paper overhang to lift the fudge from the pan. Cut into small squares.

Notes

  • For an extra indulgent finish, you can melt 1/2 cup of chocolate chips with 1 teaspoon of coconut oil and drizzle it over the top before chilling.
  • If you want a slightly firmer fudge, use creamy peanut butter that is not the natural, oily kind.
  • This recipe is naturally gluten free and is a great option for holiday candy making.
