  • Place whipping cream (1/4 cup), unsalted butter (1/2 cup), and peanut butter (1 cup) in a heavy-bottomed saucepan and heat over medium. Continually stir as the butter melt.
  • Once fully combined, remove saucepan from heat and whisk in sweetener (1 cup).
  • Pour the mixture into an 8x8" baking dish lined with parchment paper.
  • Place baking dish in the fridge until the fudge fully sets (at least 3 hours!).
  • Remove from the fridge and cut the fudge into 16 squares. Enjoy!


  • Lakanto, Swerve, or Erythritol. I stick to Lakanto and Swerve which are a 1:1 swap with traditional sugar. If using a different brand of Erythritol, keep in mind it's 70% as sweet as sugar, so you may need to add more to taste. 
  • Peanut Butter often contains added sugar. Read labels carefully before purchasing -- I love Justin's or Trader Joe's brand.
  • Nutritional information is based on 1 slice if you cut this fudge into 16 slices, and does not include the chocolate drizzle:
