Ingredients

Scale

Main Ingredients

  • 1 cup (250g) creamy peanut butter
  • 1 cup (2 sticks or 230g) unsalted butter
  • 1 teaspoon pure vanilla extract
  • 4 cups (460g) sifted confectioners’ sugar

Optional

  • 1/4 teaspoon salt
  • 3/4 cup add-ins, such as chocolate chips, peanuts, or Reese’s Peanut Butter Cups

Instructions

  1. Prepare the pan: Line an 8-inch or 9-inch square baking pan with aluminum foil, leaving an overhang on the sides to lift the fudge out later for easy removal.
  2. Melt ingredients: In a large microwave-safe bowl, melt the peanut butter and unsalted butter together. For easier melting, slice the butter thinly. Microwave in 1-minute intervals, stirring between each interval, until the mixture is completely melted and smooth.
  3. Add flavorings and sugar: Remove the melted mixture from the microwave. Stir in the vanilla extract thoroughly using a silicone spatula or wooden spoon. If you like a slight salty-sweet balance, add the optional salt. Gradually add sifted confectioners’ sugar, stirring continuously until fully incorporated. The mixture will become very thick, resembling cookie dough.
  4. Incorporate add-ins: If you’re using any add-ins like chocolate chips, peanuts, or Reese’s Peanut Butter Cups, fold them gently into the warm fudge mixture now.
  5. Set the fudge: Press the thick fudge mixture firmly into the prepared baking pan. Smooth the top with the back of a spatula or spoon. The top may appear somewhat oily. Cover the pan tightly with aluminum foil.
  6. Chill and serve: Refrigerate the fudge for at least 4 hours or until completely firm. Once set, use the foil overhang to lift the fudge out of the pan and cut it into pieces.
  7. Store: Keep the fudge in an airtight container in the refrigerator for up to 1 week to maintain freshness.

Notes

  • Make sure to sift the confectioners’ sugar to avoid lumps in your fudge.
  • Using creamy peanut butter is key for a smooth texture; chunky peanut butter will change the consistency.
  • Chilling time can be extended overnight for firmer fudge if desired.
  • The optional salt balances the sweetness and enhances peanut butter flavor but can be omitted for a sweeter fudge.
  • Customize your fudge by folding in your favorite mix-ins for extra texture and flavor.
  • If the fudge becomes too thick to stir, warming it slightly in the microwave can help.
  • Cut fudge with a sharp knife warmed under hot water for clean slices.
