Sugar Free Peanut Butter Fudge Recipe
I cannot stay away from this creamy and rich sugar free peanut butter fudge recipe. This recipe is so easy, I don’t know why it took so long to start making homemade fudge!
The hardest part about making the recipe is having to wait an hour for it to set. This recipe has very minimal prep, ingredients, and is cooked in under 15 minutes. Ridiculously quick and easy for homemade fudge.
This sugar free peanut butter fudge is also a crowd-pleaser. While I have used Powdered Swerve to make sweets in the past, the high amount of sweetener used in these types of recipes can have an undesired effect. If you’re keto, you’ll know all about the dreaded “cooling effect”. The cooling was a bit too much for my family, using Monk Fruit sweetener in my baking has definitely been a game-changer.
Now for the star of the show! The peanut butter. While it’s totally fine to use store-bought peanut butter, beware of the sugar content. Most store-bought peanut butter has added sugar and sweeteners which can be very detrimental to keto diets, especially anyone already in ketosis.
In my home, we love homemade peanut butter. This sugar free peanut butter fudge recipe gave us a chance to whip out the peanuts and the food processor. If you’re making your own peanut butter I suggest using unsalted, dry-roasted peanuts for the most delicious results.
Please every peanut butter lover you know with this sugar free peanut butter fudge. They’ll never guess how easy it was to make!
Sugar Free Peanut Butter Fudge Ingredients
Peanut Butter: Of course you need peanut butter for sugar free peanut butter fudge! For this recipe, I used 1 cup of creamy peanut butter.
Perfect Keto Peanut Butter Collagen: I’ve also added ⅓ cup of peanut butter collagen to make the fudge a bit more nutritious and help the consistency of the fudge.
Monk Fruit Sweetener: I have found that monk fruit sweetener is better than other sweeteners in large amounts, making it perfect for baking, ¾ cup should do the trick.
Butter: You’ll also need a ½ cup of butter for your fudge.
Vanilla Extract: Adding ½ teaspoon of vanilla extract will give the peanut butter fudge a delicious finishing touch.

Questions you might have
Can you have peanut butter on a keto diet?
Eaten in moderation, peanut butter can be the perfect keto-friendly snack. However, if you’re worried about exiting ketosis, you might want to make sure to stick to natural peanut butter. The smaller the ingredients list, the better!
Why won’t my sugar free peanut butter fudge harden?
If your fudge is having trouble hardening, your mixture might be undercooked. You can try adding a bit more butter (or some water) and reheating the fudge mixture.
Why did my fudge turn to caramel?
Using an incorrect temperature while cooking the fudge can leave you with a chewy, caramel-like texture. Luckily this is pretty easy to fix by reheating, or you can just enjoy the chewy fudge if you prefer.
