Make this easy, no-bake peanut butter fudge using only three simple ingredients for a melt-in-your-mouth dessert that is perfect for gifting or quick sweet cravings.

Ingredients

Scale
  • 1 cup creamy peanut butter
  • 1 (14 ounce) can sweetened condensed milk
  • 3 cups powdered sugar, sifted

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 peanut butter and sweetened condensed milk. Microwave on high for 60 seconds.
  3. Stir the mixture until it is completely smooth. If necessary, microwave for another 15 seconds and stir again until fully combined and smooth.
  4. Gradually add the sifted powdered sugar to the peanut butter mixture, stirring until fully incorporated. The mixture will become very thick.
  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. Lift the fudge out of the pan using the parchment paper overhang. Cut into small squares before serving.

Notes

  • For a richer flavor, use natural peanut butter, but ensure you stir it well before measuring.
  • If you prefer a classic, slightly firmer fudge, you can substitute the powdered sugar with 1 cup of melted white chocolate chips and 1/2 cup of butter, omitting the microwave step and melting all ingredients together on the stovetop over low heat.
  • Store leftover peanut butter fudge in an airtight container in the refrigerator for up to one week.
