Low Carb Peanut Butter Fudge

Alton Brown has created a rather tasty recipe for Peanut Butter Fudge. However, since it requires an entire pound of sugar per batch, it's not something to try if you're watching carbohydrate intake. 

Luckily there are products like Powdered Swerve that allow you make a delicious peanut butter fudge without all the sugar. If all you can find in your area is plain erythritol, you can make your own powdered version by pulsing it in a blender.


  • 8 oz unsalted butter
  • 1 cup creamy natural peanut butter (with no added sugar)
  • 1 tsp vanilla extract
  • 1/4 cup powdered Splenda
  • 1/4 cup powdered Swerve or erythritol

Combine the butter and peanut butter in a microwave-safe bowl. Microwave for 2 minutes on high. Stir, then microwave on high for 2 more minutes. (Caution! It will be hot!) Add vanilla and powdered sugar to the peanut butter mixture and stir with a wooden spoon. Spread into a 8 by 8" silicone pan and refrigerate until cool (2-3 hours). Cut into 1-inch pieces and store in the refrigerator.
