Description

A rich, creamy peanut butter fudge made with just three ingredients in the microwave—quick, nostalgic, and perfect for gifting or satisfying a sweet craving.


Ingredients

  • 1 cup (2 sticks / 227 g) unsalted butter, room temperature
  • 1 cup (258 g) creamy peanut butter (not natural)
  • 4 cups (500 g) confectioners’ sugar

Instructions

  1. Line an 8×8-inch baking dish with parchment paper, leaving an overhang on two sides.
  2. In a large microwave-safe bowl, combine butter and peanut butter. Microwave in 30‑second intervals, stirring each time, until melted and smooth.
  3. Add confectioners’ sugar and stir until fully combined—a thick mixture.
  4. Transfer to the prepared pan. Place another parchment sheet on top and gently press to even out. Remove the top parchment and smooth the surface.
  5. Refrigerate for about 2 hours, or until the fudge is set.

Notes

  • Use creamy peanut butter for a smooth texture.
  • Add mix-ins like chocolate chips or chopped nuts for variety.
  • Let the fudge sit at room temperature before serving for the best texture.
  • Store in the fridge for up to 2 weeks or freeze for up to 3 months.
