Ingredients

Scale

Fudge Ingredients

  • 1 pound powdered sugar
  • 1 ¼ cups unsalted butter
  • 1 ½ cups creamy peanut butter
  • ½ teaspoon kosher salt
  • 1 ½ teaspoons vanilla extract

Instructions

  1. Sift the sugar: Sift the powdered sugar through a fine-mesh strainer into a large mixing bowl to remove lumps and ensure a smooth texture in the final fudge.
  2. Heat butter and peanut butter: In a medium saucepan over medium heat, combine the unsalted butter and creamy peanut butter. Whisk continuously and cook until the mixture begins to bubble around the edges, about 3 to 5 minutes, ensuring the ingredients fully integrate.
  3. Add salt and vanilla: Stir in the kosher salt and vanilla extract to the heated mixture, blending them evenly to enhance the fudge’s flavor profile.
  4. Combine with powdered sugar: Pour the warm peanut butter and butter mixture over the sifted powdered sugar in the bowl. Mix thoroughly with a spatula until the mixture is completely smooth and uniform.
  5. Set the fudge: Line an 8×8-inch baking pan with plastic wrap. Spread the fudge mixture evenly into the pan, then wrap completely with additional plastic wrap. Refrigerate for 1 to 3 hours until the fudge is firm enough to cut but still soft enough to slice easily.
  6. Cut and serve: Remove the fudge from the pan by lifting the plastic wrap. Cut into small cubes. If the fudge is too hard, let it warm on the counter for a short period before slicing for easier cutting.

Notes

  • This recipe works well with other nut butters such as almond or cashew, whether smooth or chunky.
  • If you don’t have kosher salt, use ¼ teaspoon fine salt as a substitute for a less coarse texture.
  • For easier removal and cleanup, you can line the pan with parchment paper instead of plastic wrap.
  • Adjust refrigeration time for desired firmness; less time will yield softer fudge, more time will produce a firmer texture.
  • Consider using an 8×8-inch pan for thicker pieces or a 9×9-inch pan for thinner, more numerous cubes.
