The Inspiration For This Recipe:

Put simply, I wanted to make a fudge recipe that I would eat.

I have always found the traditional fudge recipe to be too sweet so I never ate it as a kid.

For this reason, I began making my own fudge recipes using cleaner ingredients many years ago. If you’re looking for a Keto Peanut Butter Fudge recipe that does not include chocolate, give it a gander!

This low-carb chocolate fudge is super rich and creamy, perfect for the dark chocolate lover, and ideal for those who love a sweet treat but prefer them less sweet.

Now of course if you like your fudge to be lightning bolt sweet, you can easily add more sugar-free confectioner’s sugar, or 1/2 cup of sugar-free chocolate chips! Play with the portions to your heart’s delight!

This easy fudge recipe requires minimal simple ingredients. Ready to dive in? Let’s go!

Ingredients for Low-Carb Chocolate Fudge:

Unsweetened Nut Butter of Choice: The majority of the volume of this recipe comes from your favorite nut butter. This, in conjunction with butter, takes the place of heavy cream in classic fudge.

I use cashew butter because I love the creamy flavor. Not all grocery stores carry cashew butter, so you may need to source it online or go to your local natural food store (I got mine at Whole Foods). 

You can use peanut butter or almond butter depending on the flavor you’re going for. If you love peanut butter chocolate fudge, I say go for that peanut butter! Cashew butter contains twice as many carbs as peanut butter, so if you’re aiming for an easy keto fudge recipe, use peanut butter.

Unsalted Butter: Melted butter gives the fudge a silky smooth texture so that it has that classic fudge consistency and iconic buttery flavor. It makes it nice and soft and rich, which is important when it comes to fudge!

For a dairy-free option, replace the butter with 1/3 cup of coconut oil or coconut milk. You can also use ghee!

Raw Cacao Powder: The chocolate portion of this chocolate adventure. Raw cacao powder has a rich and creamy chocolatey flavor, which I prefer over regular unsweetened cocoa powder. If you like the bitterness of regular cocoa powder, go for it! Add 1/2 cup of chocolate chips to the recipe to make it even richer, sweeter, and chocolatier.

Sugar-Free Confectioners Sweetener: In order to sweeten the fudge without adding sugar, I use sugar-free confectioners sweetener (aka sugar-free powdered sugar). The finely ground confectioners sweetener ensures the substance mixes into the fudge without graininess. If you want to give it a shot with regular sugar-free granulated sweetener, so for it, but note that the texture will not be creamy.

I recommend Lakanto Sugar-Free Powdered Sugar which is made with monk fruit, Allulose, or Swerve Confectioners Sweetener for my top three recommendations. If you have a favorite sugar substitute or preferred sugar alcohol, feel free to use it.

Sweeten this sugar-free fudge recipe to your personal taste. I like mine less sweet but for a sweeter fudge, simply add more sugar-free sweetener or some sugar-free chocolate chips.

Vanilla Extract & Sea Salt: Vanilla extract and sea salt provide that warmth and big bold rich flavor that makes fudge so enticing. It’s these little touches that make a treat irresistible!

Let’s make this easy keto chocolate fudge recipe!

How to Make Low-Carb Chocolate Fudge:

Line an 8-inch cake pan with parchment paper. You can also use a 9” x 5” loaf pan for thicker fudge.

Melt the butter in the microwave in a heat safe bowl. If you’re adding sugar-free chocolate chips, melt them with the butter. Note: if you’re familiar with using a double boiler, you can go this route instead of using the microwave.

Add the cashew butter (or peanut butter or nut butter of choice) to the melted butter and mix until creamy.

Stir in the cocoa powder, sugar-free powdered sugar, vanilla extract and sea salt and mix until creamy. If the mixture is difficult to stir together, heat it in the microwave for 15 second increments until it is easier to combine.

Pour the fudge mixture into the prepared pan and spread it into an even layer.

Refrigerate fudge for at least 2 hours, or until it has set up completely. 

Slice and serve!

Store fudge in an airtight container in the refrigerator for up to 2 weeks. You can also freeze it in a zip lock bag for up to 4 months.

Recipe Tips:

Make sure cashew butter is at room temperature.

How to Store Low-Carb Chocolate Fudge:

Although this fudge is stable at room temperature, I store leftovers in a sealed container in the refrigerator (or freezer) because it contains butter. I also like my fudge to be solid rather than soft, but if you prefer very soft fudge, it can be stored at room temperature for a few days.

Is This Recipe Keto?:

If you’re using peanut butter to make the fudge, it is keto-friendly for most people following a ketogenic diet.

Making the fudge the way I do using cashew butter will result in a low-carb dessert and work for those on a low carb diet, but may be too high in carbs for folks following a keto diet.

Depending on your carb intake, this fudge may not be compliant with your keto lifestyle. It still is sugar-free and won’t spike your blood sugar (so ideal for those with high blood sugar), but it contains 12 grams of carbohydrates, 2 grams of fiber, and therefore 10 grams of net carbs per piece. You can always slice the fudge into smaller chunks than I do, or use peanut butter.

Can anyone fill me in on Swerve? What it’s made of and how it’s processed, I didn’t think this was really a “clean eating” item.

Hi Penny, Swerve is erythritol, which is derived from corn. You can use monk fruit sweetener or any powdered sugar-free sweetener you like..you don't have to use Swerve if it's not your jam ;) xo

Can I substitute almond butter with the cashew butter

Julia

Wednesday 27th of January 2021

Hi Anna,

Absolutely. The fudge will turn out a bit gritty due to the texture of almond butter, but it will still taste great :) xoxo

Pretty tasty. My kids even enjoyed it. I did pop mine in the freezer for maybe 30 minutes to firm it up a little more.

Could sunflower butter be used in place of the cashew butter? My husband is allergic to nuts.

Hi Shannon!

Yes, absolutely! In fact, I use sunflower butter in fudge all the time! I hope you and your husband enjoy this one :D xoxo
