Sugar Free Peanut Butter Fudge

If I could eat peanut butter and chocolate every day I most certainly would.

I don’t, but I’d love to be able to be…… you know that girl…….eat whatever she desires, doesn’t exercise, stays perfectly tiny, has a few babies, slims down without even trying……yeah, you have someone in your life like that just as we all do, am I right?

I’ve never been blessed to have a skinny frame. I’ve never been able to eat whatever I’ve wanted without consequences. I’ve had to work off every.single.pound of pregnancy weight. 3 times.

Oh before babies I was able to lose weight effortlessly. I remember being fed up at 22. Being overweight and unhappy. Hating living in my own skin. I had just graduated college. I weighed 159 pounds on my 5 foot 2 and 1/2 inch frame.

I was ready and I went for it for the first time with a healthy life style change. I exercised and ate nothing in between meals. I could still eat whatever I wanted, sugar included and in 6 months I was down to 124 pounds.

But I was also 22. I am maintained that weight for 7 years before the first baby.

That was then, this is now. And being 43, it’s a lot harder to lose without a concentrated effort. And as time has gone on, I’ve come to realize the things that worked to lose weight after my 3rd baby 9 years are not helping me working for me now. Bodies do change over time. I’ve come to the conclusion my body at this age needs a whole lot less carbs to see the scale move where I want it.

That’s where this recipe comes in.

If I’m cutting carbs to lose weight I need healthy fats to keep me satiated so I don’t turn to carbs. Hence, comes in the FAT BOMBS! Just a small piece is enough to make you feel satisfied!

Is Peanut Butter Keto?

Traditional peanut butter fudge is not keto friendly so those of you who are keto dieters will need to avoid because of the high carbs and sugar. But my healthy fudge recipe is keto friendly using peanut butter that does not contain any added sugars.

But my healthy fudge recipe is keto friendly using peanut butter that does not container any added sugars. You want to make sure you purchase natural peanut butter that doesn’t contain anything but peanuts and maybe salt. You could make your own homemade peanut butter, but it’s easy enough to find store bought without sugars, just be sure to read the nutritional information label.

How to Make Peanut Butter Keto Fudge

Ingredients

You only need 3 ingredients for this fudge plus a couple of optional ones if you so choose. Natural peanut butter, coconut oil and unsweetened almond milk makes the base of this keto fudge recipe.

Even without cream you will be amazed how this makes for a creamy peanut butter fudge. A sugar-free sweetener is completely optional as is vanilla extract. There are plenty of keto sweeteners on the market, but I don’t recommend some for this recipe.

For instance, I would not recommend using a granular low carb sweetener as it will make gritty fudge and won’t be smooth. When I want a sweet taste in a keto dessert, but not the bulk, I use vanilla stevia in mine. Monk fruit sweetener is also a great option in liquid form or use a low-carb confectioners or powdered sweetener.

Please see my Sweetener Guide & Conversion Chart for more specifics recommendations.

Directions

Slightly melt or soften the peanut butter and coconut oil together in the microwave or low heat on the stove.

Add this to your blender and add the rest of the ingredients.

Blend until combined.

Pour into a prepared pan lined with parchment paper. 8 by 5 loaf pan.

Refrigerate until set, about 2 hours.

If using chocolate sauce, whisk ingredients together and drizzle over fudge after it’s been set. Once set you can lift out of the pan onto a cutting board and slice into servings.

Best if kept refrigerated because at room temperature they do melt easily.

Can I add chocolate and make keto chocolate fudge?

You don’t need to add a sugar-free chocolate sauce drizzle, but of course I did. I’m a lover of chocolate ya know.

You could add in some sugar-free chocolate chips into the batter or melt some and swirl it into the batter.

As far as losing weight and eating peanut butter and chocolate like this fudge, well, the hardest part is if you can handle a piece a day without overindulging in more than that, then by all means knock yourself out.

Or just enjoy some on the weekend for a little indulgence. Whatever makes you happy friends.

But for only 3  grams of net carbs and  a good amount of healthy fat from the coconut oil and peanut butter, just a piece will be completely satisfying.

And you will be smiling and thanking me in each creamy fudge bite!

Nutrition information is without optional chocolate sauce.

One more thing! I was called out on the fact that there are more than 3 ingredients here so I must respond to that by saying, I did not count salt as it can be left out for lower sodium and not needed unless you peanut butter is unsalted.

Stevia is completely optional and many of you may choose no sweetener at all and the chocolate sauce is optional as well. So technically it might look like more than 3 ingredients, but the main 3 are all you really need to make this fudge. The end.

How to Store Peanut Butter Fudge

It’s best to store this keto peanut butter fudge in an airtight container in the refrigerator for up to a week. You can also freeze for up to 2 months.

  1. i saw that someone used coconut milk- was that the firm bit of the coconut milk, or the solid bit, or both together. Sorry for the stupid question!!

  2. Why is the sweetener listed as “optional”? It’s not optional. It just tastes like oily peanut butter if you leave the sweetener out.

    1. That’s exactly what I got. Now I don’t know what to do with all this oily peanut butter bites ? Any suggestions?

  3. used regular peanut butter but has been in the fridge for the whole afternoon and won’t set.. Any ideas?? Thanks

    1. Might be the measurement of coconut oil you used. Try freezing it for a while.

  4. 4 stars
    Just tried making this with almond butter and coconut milk. Once I combined the warm oil & nut butter mixture with the coconut milk, the nut butter and coconut milk kind of curdled together creating a lumpy mush in a pool of oil. Definitely going to let it cool before combining next time…

    1. Did you use your blender to combine it? The coconut oil does not need to be completely melted, just softened with the nut butter.

  5. 4 stars
    Thanks for this recipe. I just put it in the fridge! I sweetened it with 2 TBSP of Swerve. We’ll see how that turns out. I tasted it after every TBSP and I think 3 might be enough. ๐Ÿ™‚

  6. It’s so sad that your body just doesn’t respond the way it did when it was younger. I miss carbs when I cut back and then I binge on them. I miss my younger metabolism and the fact that one push-up back in the day would give me washboard abs.

  7. Dear Brenda,i have a problem.I have the powerder stevia.Every time i try to use it in a recipe it taste so bad.I am a Diabetic and i’m always wanting sweets.tell me what im doing wrong . It is aways to sweet and has a after taste .then i have to chunk it. My husband thanks maybe using to much. i have used just a pinch and it still taste bad. Help

    1. Eva, my experience is that powdered Stevia has a very bitter aftertaste. It can only really be useful in coffee or mixed with other sweeteners. Just a tiny bit is all you can really use without ruining the flavor of whatever you’re eating. I recommend erythritol and a product made with it, called Swerve. My diabetic uncle LOVES the peanut butter cookies I make for him with it. I hope this helps.

    2. How much Swerve would you sub in this recipe? I don’t have liquid stevia, but I do have Swerve. I can attempt to guess, but I hate taking the risk!

  8. It’s amazing what cutting out on sugar can do. I’ve been using a lot of sugar replacements lately and find that I really enjoy them. I’m going to try your recipe. It looks delicious! Who knew you could eat fudge and not feel guilty?

  9. You think losing weight is hard NOW, wait ’til menopause—it becomes almost IMPOSSIBLE then because of the estrogen loss. Lower your carbs even more, watch your protein intake to avoid gluconeogenesis, and get more active if you aren’t already, and that should help you power past that menopause plateau. Meanwhile, lose it NOW while you still have some estrogen left–start solving those sweet cravings with L-glutamine instead of food.

    1. Good morning…. You can keep your oestrogen levels up naturally by eating milled flax seed – in smoothies or in ‘bread’ recipes… ๐Ÿ™‚

    2. Do u mean to take L-glutamine to cut the sugar cravings? I need help with that so bad and if it works Iโ€™ll try anything! I bought a sugar blocker and it just made me feel awful and weird

    1. Can I use coconut cream instead of coconut oil? I tried it with coconut oil and it was yummy but I have a can of coconut cream just begging to be used.

    2. I’ve not tried it so I’d love it if you would and come back and let me know how it worked in comparison.

    3. 5 stars
      I made it with the coconut cream in the can, but not the liquid, and the fudge is delicious. I froze half the batch and tried that one. Yum. Not sure if that alters the nutrition.

    4. Can I have the recipe? I’ve looked and can’t find step by step ingredients. Do you by chance have one for mint chocolate fudge?

    5. Brenda the serving size “2 pieses” is that an ounce piece? 2 ounce piece?
