Keto Chocolate Peanut Butter Fudge

It’s not Christmas without the fudge! This KETO FUDGE has a chocolate base with a swirl of creamy peanut butter throughout. Rich, sweet, and loaded with chocolate. This is a decadent keto dessert that’s perfect for the holidays.

I’ve been a total sucker for fudge my whole life. So rich, sweet, and satisfying!

We don’t make fudge often, but during the holidays? It’s game on!

Fudge is basically a Christmas requirement in my family.

My grandma used to make a batch of chocolate fudge and a batch of peanut butter fudge every year and it was heaven.

I like to marry them together myself, so here’s my keto version of chocolate peanut butter fudge.

You won’t believe how easy this is – no candy thermometers or boiling sugar or anything like that!

Ingredients:

bakers chocolate chopped on wooden cutting board.

Chocolate: We’re just using the unsweetened bars of bakers chocolate that you can find in any grocery store. They’re budget friendly and easy to find. You’ll want to chop them up before using.

Peanut Butter: We’re using a peanut butter with just 2 net carbs per serving and that’s what our nutrition info is calculated on. Please adjust accordingly if you use a higher carb peanut butter. We used this peanut butter from Thrive Market – we love Thrive Market because the prices are cheap and you can shop by dietary needs. Their keto section is impressive!

Powdered Sweetener: We use and love Laknato Monkfruit Sweetener in our house. It comes in a classic, golden, or powdered version and we find that it is closest tasting to sugar. It has zero effect on blood glucose and can be counted as zero net carbs. Use code THATLOWCARBLIFE for 20% off your order at Lakanto.com. We use this sweetener in our keto peanut butter balls, too!

How To:

Add the chopped chocolate, butter, cream, and peanut butter to a mixing bowl and microwave until the chocolate has melted.

You’ll want to stir every 30 seconds or so to prevent the chocolate from burning.

Once your chocolate is melted, stir in the powdered sweetener, vanilla, and a pinch of salt.

Your mixture will be thick, but you should be able to stir it together fairly easily.

It’ll also look a bit granulated or chunky, but don’t worry – it turns out nice and creamy!

Spread into a foil lined 8×8 baking dish and then drizzle the top with a bit of melted peanut butter.

Use a butter knife to swirl the peanut butter in.

Freeze for an hour or refrigerate for 4 hours before cutting and enjoying!

This fudge is very rich with deep, dark chocolate flavors that are complimented perfectly with the salty peanut butter.

It’s very creamy and will start to melt in your hands a bit after too long.

We recommend storing this in the refrigerator for best results.

It should last for a week in the fridge – if you don’t devour it all first!

What can I use besides peanut butter?

We’ve only tested this recipe with peanut butter, but I believe a no-stir almond butter would work just as well!

Do be sure to use the no-stir kind so that the almond butter doesn’t separate and create a funky texture in your fudge.

  1. Hi i seem your recites on choc. pie and peanut butter fudge and cant wait to try them i am a diabetes and i will try them soon , thank you for your hard work

  2. I don’t have the s.f bakers chocolate, but have s.f. chocolate chips. Do you think that would work? If so, how much? P.S. I can see all the ingredients too.

    1. Karly Campbell

      Hi Dee! Chocolate chips have extra ingredients in there to help them hold their shape and they don’t melt as nicely. It may work for the fudge, but I’ve never tried it.

    2. Rooni Tunes

      Hi Dee! I have sugar free chocolate chips from Nuts.com and they melt beautifully and quickly in a double boiler. Haven’t tried melting them in the microwave oven. However, SF chocolate chips have a SF sweetener in them whereas baker’s chocolate, if unsweetened, has no sugar or sweetener added, so you might not need as much powdered sweetener as is called for in this recipe if you’re using sugar free chocolate chips vs. unsweetened chocolate chips. Just a thought.

  3. Shut down my ad blocker and the recipe still has missing ingredients. I will ask my son for help on this. Thanks.

  4. Several of the ingredients are missing off of the recipe. This is not the only recipe I have noticed this happening to. There is a place for the ingredients but it is blank.

      Hi Annette! It sounds like you have an ad blocker on your browser. If you turn that off, you’ll be able to see the full ingredients list. Your ad blocker is blocking them because they are affiliate links to make it easy to find the ingredient/see what brand I use. ๐Ÿ™‚

  5. The instructions talk about vanilla and peanut butter, but they aren’t listed in the ingredients. The peanut butter is a no brainer, but how much vanilla…1 teaspoon?

    1. Karly Campbell

      Hi Ceph! It sounds like you have an ad blocker on your browser. If you turn that off, youโ€™ll be able to see the full ingredients list. Your ad blocker is blocking them because they are affiliate links to make it easy to find the ingredient/see what brand I use.

      1. No… I don’t think so. I will keep my ad blocker. I need it more than I need your recipe. If that’s the way you play I don’t need to follow you.

          1. Not really a loss at all. She has posted nothing that can’t be found somewhere else that doesn’t require me to turn off my ad blocker. I have an ad blocker for a reason and I’m not turning it off so some blogger can make a few cents off of me clicking on their links. There are a lot of people that give the full recipe and put the links in parenthesis and I do click on those. It is underhanded when someone withholds part of the ingredients of a recipe to get you to click on her ads, just so she can be sure to get a penny or two.

          2. Karly Campbell

            Again, Ceph, I’m not withholding anything. The recipe is right there for all to see. If you’ve added something to your browser to block a portion of that, I can’t help it. This isn’t my fault, but yours. Please feel free to find another recipe to use.

        1. Judith K Longcore

          Looks like a winner, Karly. I’ll give it a try because anyghing that is chocoate based with peanut butter added is a must do.
          Thank You for the recipe. And your efforts in doing this blog. ๐Ÿ™‚
