Is Peanut Butter Fudge a Keto-Friendly Dessert?


If you’re craving fudge, keto peanut butter fudge is the way to go. Traditional peanut butter fudge is high in sugar and carbohydrates, making it unsuitable for keto dieters. On the other hand, our quick keto peanut butter fudge is prepared with basic ingredients like natural peanut butter and sugar-free sweetener. This sugar-free peanut butter fudge recipe only has five ingredients, one of which is optional.

What is the Carbohydrate Content of Peanut Butter Fudge?

2-3 cups pure white cane sugar in traditional stovetop peanut butter fudge! That implies there are 23 grams of carbohydrates in a single bar serving, 3 grams of fiber, and 14 grams of sugar! A bar has approximately 220 calories, with about 60 of those calories coming from sugar alone.

Peanut Butter Fudge with No Sugar


Traditional peanut butter fudge, as previously stated, may be high in refined white sugar. Our keto peanut butter fudge, on the other hand, is sugar-free and gluten-free. We used powdered erythritol sweetener instead of cane sugar. Many other brands, such as Anthony’s erythritol or Swerve erythritol, are available as a 1:1 sugar substitute. Using a sweetener not only provides a sugar-free sweetness, but it also thickens the peanut butter fudge recipe, allowing it to set correctly. If you don’t have erythritol on hand, you may use other powdered low carb sweeteners such as:

  • Monk Zero is a powdered monk fruit and erthritol-based low-carb sweetener that works with our peanut butter fudge recipe as well.
  • Lankanto Powdered Monk Fruit– Lankanto also sells a powdered erythritol monk fruit mix. It’s a perfect substitute for powdered sugar in keto recipes.
  • Powdered Allulose– If you want to create keto peanut butter fudge, allulose is another low-carb powdered sweetener to utilize. It melts easily, has no sugar alcohol, and has a pleasant vanilla taste.

All of these keto-friendly sweeteners are excellent choices for people who wish to create this keto peanut butter fudge without any additional sugar or carbohydrates.

Sweetener (powdered vs. granular)

In this recipe, we used a powdered low-carb sweetener, sometimes known as confectioners’ style. This is because a powdered sweetener will combine and spread more evenly in the fudge mixture. There is another alternative if you don’t have or don’t want to purchase powdered erythritol. Keto peanut butter fudge may be made using granular erythritol that has been powdered in a coffee grinder.

Is Peanut Butter on the Keto Diet?


Peanuts are a contentious topic in the keto and low-carb communities. Because they are technically a legume that is closely related to beans, they are not keto-friendly (1). Peanuts, on the other hand, are a fantastic low carb, fat and protein choice for most people’s diets. So don’t let the technicalities stop you from enjoying your favorite snack; simply eat your peanuts and peanut butter in moderation!

Keto-Friendly Peanut Butters

Although peanuts are keto-friendly, not all peanut butters are. You may be shocked at how much sugar is added to your peanut buttery snack, depending on the brand and ingredients you choose. Stay away from any peanut butters that include added sugar, corn syrup, or hydrogenated oils. Unfortunately, they are often the most sentimental brands, like as Jif and Skippy. Instead, choose a peanut butter made with just two ingredients: peanuts and salt.

Macros with Peanut Butter

We eat peanuts and peanut butter all the time, even if they aren’t completely keto approved from the viewpoint of the “ideal” keto diet. We like producing our own peanut butter when we get the opportunity. When we don’t have time, though, we choose traditional natural peanut butter. Two tablespoons of natural peanut butter has 190 calories, 16 grams of fat, 7 grams of carbohydrates (3 grams of fiber), 4 net carbs, and 8 grams of protein per serving.

The Most Effective Keto Peanut Butter

The simplest peanut butters are the greatest keto peanut butters. It’s a low-carb peanut butter made with just one or two ingredients. Natural peanut butters are generally the best, but double-check the macros and ingredients before buying. Don’t be misled by their packaging; instead, ensure sure the only ingredients are peanuts and salt, with no sweeteners or oils added.

Is it Possible to Make Keto Fudge with Homemade Keto Peanut Butter?


This peanut butter fudge recipe is very easy to make and frequently just needs items that you already have on hand. If you have a thick keto peanut butter on hand, go ahead and use it! Since you prepared it yourself, it will be the most natural and fresh peanut butter you’ve ever had. If your homemade keto peanut butter is excessively liquid or greasy, don’t use it. It won’t set correctly if it’s too liquidy, and your keto peanut butter fudge will end up being a messy mess.

Peanut Butter Fudge with Low Carbs and No Dairy

There is just one dairy component in this dish, and that is butter. Because butter is creamy and soft when left at room temperature, it works nicely with fudge. If you’re lactose intolerant, consider replacing the butter with coconut oil or dairy-free butter. We can’t guarantee the same taste profile, but we can guarantee it’ll be delicious in its own right.

Peanut Butter Fudge on a Keto Diet Recipe

We guarantee you’ll cook our keto peanut butter fudge recipe again and again since it’s so delicious and simple to prepare.



You just need 5 ingredients to create keto peanut butter fudge. They’re already in most people’s homes. Natural low-carb peanut butter, unsalted butter (since we’ll be adding salt later), powdered erythritol sweetener, vanilla essence, and flakey salt to sprinkle on top are all required. The salt is optional, but we like the sweet-salty contrast. If you use unsalted butter and peanut butter, it’ll be much better.

Peanut Butter Fudge with Low Carbs

Prepare a loaf pan by lining it with parchment paper. Then heat the butter in a microwave-safe basin until it has completely liquified.

Now add your preferred powdered sweetener.

To ensure that all of the sweetener has dissolved, whisk vigorously. If it isn’t completely mixing, microwave it for 30 seconds at a time.

Combine the peanut butter and vanilla essence in a mixing bowl. Re-whisk until all of the ingredients are combined.

If desired, add flakey salt on top of the fudge foundation in the parchment paper lined pan.

Refrigerate for at least an hour, or until the pudding is completely set. The fudge may then be cut into 14 pieces with care. To make slicing frozen fudge easier, we run a knife under hot water.

Sugar-Free Peanut Butter Fudge on a Keto Diet Storage

Our keto peanut butter fudge keeps for up to a week in an airtight jar in the fridge. If you wish to keep the fudge for up to three months, you may easily freeze it. Simply slice the fudge and put pieces in an airtight freezer bag between parchment paper.

Making the Best Peanut Butter Fudge on a Keto Diet Tips

It’s nearly difficult to screw up this recipe since it’s so easy. There are, however, a few tricks to creating the creamiest and smoothest keto peanut butter fudge every time. The following are our top recommendations:

  • Use Thick Peanut Butter– Too runny peanut butter will result in a watery batter that will not set. It’s preferable to err on the side of caution and use thicker peanut butter than it is to use peanut butter that is too thin.
  • Add Some Extra Protein– If you want to make the fudge more substantial, add a scoop or two of protein powder to the mix.
  • Keep it Cool– To prevent your final fudge from becoming too soft and melting in your fingers, place it in the freezer or fridge.

These are just a few of the tricks we’ve discovered for keeping our fudge taste great. If you have any other suggestions, please share them in the comments section below so that we may include them in the article.
