Instructions
 

  • Grease an 8x8-inch glass baking dish. Set aside.
  • Melt butter and peanut butter together in a small saucepan over low heat, stirring frequently until smooth.
    A pot on a stove containing a mixture of melted butter and peanut butter, partially blended together.
  • Remove from heat, then add the vanilla and salt.

  • Slowly add the sugar one cup at a time.

Notes

  • My original recipe was inspired by a vintage church cookbook and used 3.5 cups of powdered sugar. I've since reduced it down to 2 cups.
  • Leaving the fudge in the refrigerator for too long can make it dry and overly firm. If this happens, bring it out to warm up on the counter for 10 minutes before serving.
  • Heat up a knife under hot water then use it to cut into the fudge to get slices with clean, smooth edges.
Store: It’s best to keep peanut butter fudge slices in an airtight container at room temperature, away from direct sunlight. If you want them refrigerated, transfer slices into an airtight container and store in the fridge for up to 2 weeks.
