Creamy Peanut Butter Fudge

Creamy Peanut Butter Fudge

This is a rich, melt-in-your-mouth fudge that uses the heat from the melted butter and peanut butter to “cook” the powdered sugar into a smooth, fudge-like consistency.

  • Prep time: 10 minutes

  • Chill time: 1–3 hours

  • Yields: One 8×8 inch pan (approx. 36-64 squares)

Ingredients

  • 1 lb (16 oz) Powdered sugar (Sifted)

  • 1 ¼ cups Unsalted butter

  • 1 ½ cups Creamy peanut butter

  • ½ tsp Kosher salt

  • 1 ½ tsp Vanilla extract

Instructions

  1. Prepare the Sugar: Sift the powdered sugar through a fine-mesh strainer into a large, heat-proof bowl. This ensures there are no lumps in your finished fudge.

  2. Melt and Combine: In a medium saucepan, combine the unsalted butter and creamy peanut butter. Place over medium heat. Whisk constantly until the mixture is fully combined and small bubbles begin to appear around the edges (about 3 to 5 minutes).

  3. Season: Remove the pan from the heat. Immediately stir in the kosher salt and the vanilla extract.

  4. Mix: Pour the hot peanut butter mixture directly over the sifted powdered sugar. Using a sturdy spatula, mix vigorously until the sugar is completely incorporated and the mixture is glossy and smooth.

  5. Set: Line an 8×8-inch baking pan with plastic wrap (leave some overhang on the sides for easy lifting). Pour the fudge into the pan and smooth the top. Fold the excess plastic wrap over the top to cover it.

  6. Chill: Refrigerate for 1 to 3 hours. You want it firm enough to hold its shape when sliced, but not so cold that it becomes brittle and cracks.

  7. Slice and Serve: Lift the fudge out of the pan using the plastic wrap. Cut into small cubes. If it feels too hard to cut, let it sit on the counter for 10 minutes to soften slightly.
