I am a peanut butter person and have been known to eat an apple just so I could have some peanut butter with it. So over Christmas an old friend made some peanut butter fudge for me and I could not resist. It was so good but it had so many carbs and that is why I came up with this easy keto peanut butter fudge recipe.

Its super easy with only 3 ingredients and it only takes a few minutes to whip up. I shared some with my diabetic father as well as my hubby and son and they all gave it a thumbs up! The best part is each piece only 1.1g net carbs! Trust me you only need 1 piece but even if you had two or three it won’t blow your diet. Now let me show you how to make some sugar free peanut butter fudge!

3 Ingredients For Low Carb Peanut Butter Fudge

I have tried this a few ways and I still have a little more experimenting to do. However today’s batch was perfect and all I used was natural peanut butter, Swerve confectioners sweetener and butter. That is all.

If you like keto sweet treats I recommend buying a big bag of Swerve confectioners online. It’s cheaper and I use this for all my sweet recipes. They make a granular one and it’s good but this seems to work better. I also like Swerve brown sugar sweetener. It’s just like regular brown sugar with 0g net carbs.

Low Carb Peanut Butter

I really like this brand of peanut butter from Aldi. It doesn’t have any added sugar and there are 4g net carbs per 2 tablespoons which is pretty good for peanut butter. There are also many low carb brands on Amazon. I know people have talked about Teddie all natural peanut butter. I have not tried it personally but it has the same macros as the Aldi brand I used.

How To Make Keto Peanut Butter Fudge!

Make sure you butter is softened. If you are in a hurry (and I’ve done this) you can microwave the butter for 15 seconds or so to make it softened. But it’s better to do it the right way because if you get it wrong in the microwave it will liquify too much and not work in the recipe. So watch it carefully.

In a mixing bowl cream the butter and Swerve confectioners sweetener until nice and creamy. Then add in the peanut butter and mix again until well combined. It should look like the photo above.

Next spoon it into your containers. I used these two smaller glass containers. I wasn’t sure I had enough for a larger glass dish so I had to use two. Smooth it with a spoon or spatula. I had a little trouble getting it perfect but I didn’t care. I just wanted to eat it!

NOTE: if you want to make it easier to come out of the container, line the container first with wax or parchment paper. Cut it so the ends come all the way up the sides so you can lift it the whole thing out by the paper to cut into squares.

I did not do that and it still came out fine but I was impatient and if I did that it might have have looked a little neater.

As you can see above my squares were not so neat and smooth on top. If that bothers you for some reason, note that you can cut the uneven part off and make it look more perfect. I’m telling you in case you wanted to give this as a gift.

Easy Keto Fudge Recipe Notes And Tips

  • This only requires 3 ingredients but it’s important you use the lowest carb peanut butter you can find and the Swerves confectioner sweeter. Granular sweetener may make it grainy because you are not heating it to make it dissolve.
  • Line your containers with wax paper or parchment paper if you want to make it easier to cut when it’s done.
  • This recipe made 28 pieces of fudge. The nutritional information will change if you make bigger or smaller pieces. I felt 1 piece was very satisfying because it’s so sweet but you can play around with the size to fit your the amount of carbs you want to have.
  • Please store this in the freezer or refrigerator because it can get pretty soft if left out. I keep it in the freezer and grab one when I want something sweet and it’s still soft enough to eat.

Well I thoroughly love this recipe and I can’t wait to try more flavors. If you crave something sweet every now and then this is a good one to keep in the freezer. Also I like to make this diabetic fudge for my father in law so he can indulge and not worry about his sugar. So if you have a diabetic in your life this is a nice keto dessert for them to try.

The nutritional information based on 28 pieces for 1 piece is:

112 cals / 11.2g fat / 2g carbs / 0.9g fiber / 2.4g protein = 1.1g net carbs

    What size baking dish did you use?

      Hi Tedi, I used two small glass dishes – one was about 4.5″x6.5″ and the other was 5″x5″. You can use any size baking dish you want. That will just effect the size of the pieces you cut. Here is the nutrition information for the whole batch. You can then divide by the number of pieces that you make yourself. Hope that makes sense. Please let me know if you have any other questions.

      3,149 cals / 312.3 fat / 56.1g carbs / 24g fiber / 65.9g protein = 32.1g net carbs (whole recipe)

      112 cals / 11.2g fat / 2g carbs / 0.9g fiber / 2.4g protein = 1.1g net carbs

FAQs

Why did my peanut butter fudge not get hard? ›

Fudge Didn't Set

If your fudge turned out super sticky, or it didn't set as it cooled, it probably never got hot enough. This mistake is super easy to avoid if you use a candy thermometer and cook the fudge to the temperature specified in the recipe (usually between 234 and 239°F).

Why won't my condensed milk fudge set? ›

The most common culprit behind unset fudge is inaccurate temperature control. If the sugar mixture hasn't reached the correct temperature, your fudge won't set. Ensure you use a reliable candy thermometer and follow temperature guidelines meticulously to achieve the desired consistency.

Why is my peanut butter fudge dry and crumbly? ›

If it doesn't boil, your fudge will end up too mushy, and if it cooks for too long, you'll end up with a dry, crumbly mess. This is why many recipes recommend using a candy thermometer, so you know exactly when to remove your mixture from the heat.

What not to do when making fudge? ›

Never stir the mixture during cooking or sugar could crystallize again. The mixture may seize and become grainy. Use a candy thermometer or conduct a cold water test to check if the fudge is done. Do not rely on the cooking time indicated in your recipe.

How do you make fudge creamy and not grainy? ›

It's not brittle or crumbly, at least not unpleasantly so. By cooling the fudge prior to agitation (like in the recipes included in this article), on the other hand, you'll get much smaller, finer sugar crystals and a finished fudge with a smooth, creamy texture.

What makes fudge softer? ›

If you don't heat your fudge to a high enough temperature, you'll end up with a soft product. And if you heat the mixture too much, your fudge may be harder than you'd like.

What can you do with peanut butter fudge that didn't set? ›

To fix it, you can reheat the fudge mixture over low heat and continue cooking until it reaches the proper temperature. Be sure to use a candy thermometer to monitor the temperature accurately. Alternatively, you can try to salvage chewy fudge by mixing it into ice cream or using it as a topping for desserts.

How to fix fudge that won't set? ›

I generally heat my syrup up to 235° F and let carry-over do the rest of the work. If it's overcooked (resulting in grainy fudge) or undercooked (resulting in poor setting) all you really need to do is add a bit of cream, reheat the fudge to the target temperature, and let it set again.

What to do with failed fudge? ›

My advice to you is to just pour it in a jar, call it something else delicious, and pretend you meant for it to be that way. The nice thing about my “failed” fudge is that it tastes absolutely delicious! A spoonful of the delectable treat will make you want for more.

Why won't my 2 ingredient fudge set? ›

Why won't my 2-ingredient fudge set? If your fudge isn't setting, it might be due to underheating the mixture or not chilling it long enough.

Why won t my peanut butter fudge harden? ›

The main reason is that your Fudge has not reached the optimum temperature. If your mixture only reaches 110 or 112 degrees Celsius it will always be soft. That's why we recommend investing in a sugar thermometer. Another reason your Fudge is not setting is that the ratio of liquid to sugar is too high.

Should you stir fudge while it's boiling? ›

You should mix the cream, butter, and sugar when making your fudge, but put down the spoon once it has reached its boiling point. Stirring while your sugar mixture is boiling will only form sugar crystals and make your fudge crunchy rather than silky smooth.

How do you fix crumbly peanut butter? ›

If you're down to the bottom of a jar and the nut butter is dry and crumbly (you didn't store it upside down, huh?), a surefire way to give it life is by adding some oil.

How do you keep fudge smooth? ›

So, the key to smooth yet firm fudge, pralines, and fondant is to first bring the mixture to a high enough concentration and then let it cool off somewhat before starting to stir. And once you do start to stir, stir fanatically and without stopping for the finest, creamiest texture.

What is the key to successful non grainy fudge? ›

While you ultimately want crystals to form, it's important that they don't form too early. The key to successful, nongrainy fudge is in the cooling, not the cooking.

Do you stir fudge while it is boiling? ›

Avoid Stirring Once the Mixture Comes to a Simmer

Another key part of a successful fudge texture is when you stir the mixture. Stirring the sugar and milk during the initial stages of cooking allows the sugar to dissolve. However, once the mixture comes to a boil, it's time to put the spoon down.
