Description

A refined peanut butter fudge that is smooth, satiny, and packed with peanut flavor, using minimal ingredients for an effortless yet elegant treat.


Ingredients

Scale
  • 1/2 cup (115 g) unsalted butter, room temperature
  • 1 1/2 cups (360 g) creamy peanut butter, smooth and at room temperature
  • 3 1/24 cups (420–480 g) sifted powdered sugar
  • 1 teaspoon pure vanilla extract
  • Pinch of fine salt
  • Flaky sea salt, for finishing (optional)
  • 2 tablespoons chopped roasted peanuts, toasted and cooled (optional)

Instructions

  1. Prepare the pan by lining an 8×8-inch square pan with parchment, leaving an overhang to lift the fudge easily, and lightly grease the parchment.
  2. In a medium saucepan over low heat, melt the butter until glossy, then whisk in the peanut butter until smooth and warm to the touch.
  3. Transfer the warm mixture to a large bowl, add 3 cups of sifted powdered sugar, and stir slowly; add more sugar in small increments until the mixture holds its shape but remains pliable. Stir in vanilla and a pinch of salt.
  4. Press the mixture into the prepared pan and smooth the top, scattering flaky sea salt or chopped peanuts while the surface is still tacky.
  5. Refrigerate for at least 1–2 hours until fully set, then lift the fudge from the pan and slice into neat squares with a warm knife.

Notes

To maintain a glossy surface, avoid excess moisture and use parchment paper between layers when storing. For a vegan option, substitute butter with a plant-based alternative.
