Equipment

Ingredients

  • 1 cup creamy sugar-free peanut butter no sugar added, or natural no sugar added
  • ½ cup 1 stick butter (salted and unsalted work)
  • 2 teaspoons vanilla extract
  • 1 cup Swerve powdered confectioners'
  • ¼ teaspoon salt omit if using salted butter or salted peanut butter

Instructions

  • Line an 8-inch square baking pan with parchment paper. Leave enough at the top to help you remove the fudge from the pan after it has set.
  • Add the peanut butter and butter to a medium mixing bowl. Cover the bowl and microwave for a minute at a time, until the butter is melted.
  • Remove the bowl from the microwave and add the vanilla and salt. Stir until the mixture is well combined. The bowl will be hot.
  • Add the sugar-free powdered sweetener and stir until completely combined.
  • Transfer the peanut butter fudge into your prepared pan, smoothing the top with the back of a spatula or spoon. Cover and chill for at least 6 hours or overnight.
  • To cut the fudge, lift the parchment paper with the fudge out of the pan and place it on a cutting board before cutting into squares.
  • Store in an airtight container in the refrigerator for up to a week. Store in the freezer for up to three months.

Notes

  • Do not use a mixer. Simply mix everything by hand, it doesn't take very long. Using any electric mixer will add a lot of unwanted air bubbles.
  • Use dairy-free butter to make this fudge dairy-free.
  • Use a powdered sugar free sweetener. Granulated sweeteners don’t work well in this recipe.
  • Stove top Directions: In a medium sauce pan, melt peanut butter and butter together over medium heat. Then follow the remaining steps above.
  • It will last up to 2 weeks in the refrigerator. Freeze up to 6 months. Best to cut it before freezing and place in an airtight container.
