Keto Peanut Butter Fudge

Posted by

Ultra creamy, three ingredient Keto Peanut Butter Fudge that is only 2 net carbs per slice!


Cook Time: 6 Minutes

Chill Time: 30 Minutes

Total Time: 36 Minutes

Yield: 21


  • 8 tablespoons butter (1 stick)
  • 1/2 cup brown sugar swerve sweetener
  • 1 cup peanut butter
  • 1 teaspoon vanilla extract (optional)


  • Heat a medium size sauce pan over medium heat. Melt butter, then add brown sugar. Stir continuously until sugar dissolves and it begins to simmer and a thick brown caramel begins to form. This usually takes 6-8 minutes for me.
  • When the sauce is thickened and looks like caramel remove from heat and stir in the peanut butter and vanilla extract (if using) until melted.
  • Line a loaf pan with wax paper and carefully pour the fudge into the pan.
  • Freeze 30 minutes or until completely set.
  • Peel the wax paper away from the fudge and slice. (I slice the loaf into three long skinny rows, then slice the long rows into 7 chunk size pieces.)
  • Top with sea salt as desired.
  • Store in freezer.
