Description

This delicious peanut butter fudge recipe combines creamy peanut butter, unsalted butter, vanilla, and powdered sugar to create a smooth, sweet treat that can be garnished with colorful M&M’s. Perfect for a festive dessert or a sweet snack, this no-bake fudge sets in the refrigerator and is easy to make with simple ingredients.


Ingredients

Scale

Main Ingredients

  • 1 cup unsalted butter
  • 1½ cups creamy peanut butter (NOT natural or no-stir varieties)
  • 2 teaspoons vanilla extract
  • 3¼ cups powdered sugar, sifted
  • 1 tablespoon water (for the pan)

Optional Garnish

  • M&M’s, 2-3 per piece of fudge


Instructions

  1. Prepare the pan: Using the bottom of the 8×8 baking dish as a template, cut out a piece of parchment paper to line the pan. This will help smooth the fudge and protect the top during chilling.
  2. Cut parchment overhang: Cut enough parchment paper to hang over the sides of the pan, allowing easy removal of the fudge later.
  3. Water for parchment placement: Pour 1 tablespoon of water into the bottom of the 8×8 pan to keep the parchment paper in place.
  4. Line the pan: Place the parchment paper into the prepared 8×8 pan, ensuring it is flat and secure.
  5. Heat butter and peanut butter: In a medium microwave-safe bowl, combine 1 cup unsalted butter and 1½ cups creamy peanut butter. Heat in the microwave for 60 seconds, then carefully remove and stir until smooth.
  6. Add vanilla: Stir in 2 teaspoons of vanilla extract until fully incorporated.
  7. Incorporate powdered sugar: Gradually add 3¼ cups sifted powdered sugar, about 1 cup at a time, stirring thoroughly between additions until the mixture is smooth, stiff, and no lumps or streaks remain.
  8. Transfer fudge to pan: Pour the peanut butter mixture into the prepared 8×8 pan, using a spatula to spread it evenly.
  9. Smooth the top: Place the pre-cut parchment paper on top of the fudge and use it to smooth the surface. Leave the parchment on top as you refrigerate.
  10. Chill fudge: Refrigerate the fudge for 2 hours to allow it to set properly.
  11. Score fudge: Remove fudge from refrigerator. Take off the top parchment paper and use a sharp knife to lightly score the fudge into the desired serving size squares, without cutting all the way through.
  12. Lift fudge from pan: Using the overhanging parchment paper edges, carefully lift the fudge out of the pan onto a cutting board.
  13. Slice fudge: Warm a large, sharp knife under hot water, dry it, and cut the fudge completely along the scored lines for clean slices.
  14. Add topping: Place 2-3 red and green M&M’s on top of each fudge piece as decoration, if desired.
  15. Store the fudge: Keep fudge in an airtight container. It stays fresh for 3-4 days at room temperature or up to 1 week refrigerated. Freeze for 2-3 months if desired.

Notes

  • Store fudge in an airtight container to maintain freshness.
  • Fudge can be frozen up to 2-3 months; wrap tightly in plastic then place in a freezer bag. Defrost at room temperature before serving.
  • Choice of peanut butter affects flavor and color: Peter Pan is sweeter and darker; Skippy is lighter; Reese’s has an orange tint; JIF is saltier and lightest in color.
  • Do not use natural or no-stir peanut butter as it will affect texture.
  • Use warm knife to slice fudge for clean edges and easy cutting.
