Nothing is quite like rich, chocolaty fudge during the holiday season… and my keto fudge means you don’t have to miss out on it if you’re low carb! I have a more traditional sugar free fudge in my Easy Keto Carboholics’ Cookbook (using sugar free condensed milk, which you can totally use to make any fudge recipe keto friendly). But for this one, I wanted to keep things quick and easy. It’s rich, chocolaty, and perfect for when you want a super fast treat. Whip up a batch with me for the holidays or share it for as the perfect homemade gift.
Why You Need My Keto Fudge Recipe
- Smooth, fudgy texture – This fudge is super creamy and melts in your mouth! Unlike many recipes, mine doesn’t have any grainy texture. It’s like a cross between my keto truffles and chocolate fat bombs, but even richer.
- Rich, chocolaty flavor – My keto fudge has all the sweet, deep chocolate taste you crave… except it’s sugar-free and gluten-free, without processed ingredients.
- Fast and easy – You need just 5 ingredients (plus salt), and the prep is quick. It sets up pretty fast, too!
- Perfect low carb treat – At only 0.3g net carbs and 124 calories per square, this keto dessert is easy to fit into your macros. They’re not very big, but for me even one is rich enough to satisfy that craving!
Ingredients & Substitutions
Here I explain the best ingredients for my easy keto fudge recipe, what each one does, and substitution options. For measurements, see the recipe card.
- Butter – I use grass-fed, but any unsalted kind will do. For a dairy-free option, swap in ghee or coconut oil — just know the flavor and texture will change a bit.
- Besti Powdered Monk Fruit Allulose Blend – This one is key to make your keto fudge texture silky smooth! Most other keto sweeteners (anything with erythritol — check the ingredient label regardless of what the front says!) will crystallize or not dissolve fully, leaving a gritty texture. Avoid granulated sweeteners (too grainy), liquid sweeteners (too runny), or super concentrated sweeteners (like pure monk fruit or pure stevia — too bitter). Plain confectioners allulose does work, but increase the amount to 1/3 cup.
- Unsweetened Cocoa Powder – I recommend Dutch processed cocoa powder because it’s less bitter. Other types or even cacao powder will work if you like the flavor.
- Sugar Free Chocolate Chips – You can skip them, but they give the fudge a firmer texture, which makes it easier to eat.
- Vanilla Extract – I like this brand.
- Sea Salt – Fine salt mixed in helps balance all that sweetness. I like some flaky sea salt on top too, but this is optional.

How To Make Keto Fudge
I have step-by-step photos here to help you visualize the recipe. For full instructions with amounts and temperatures, see the recipe card.
- Cream the butter and powdered Besti. I use this hand mixer, but a stand mixer also works.
- Beat in the cocoa powder, vanilla, and sea salt. If you’re adding chocolate chips, melt them in a double boiler or microwave, then beat in the melted chocolate as well. Adjust the sweetness and salt to your liking!
- Transfer to a small dish. I use these glass containers lined with parchment paper. Let the paper hang over the edges for easy lifting later. Pour the chocolate mixture into the lined container and smooth out the top with a spatula. If you’re using flaked salt, sprinkle it on now for a special garnish.
- Refrigerate and enjoy! Once your keto chocolate fudge is set, slice it into 15 bite-sized squares (3 by 5).
My Recipe Tips
- Use softened butter. If it’s hard out of the fridge, you’ll end up with little chunks.
- Whatever you do, don’t let the butter melt! Aside from intentionally melting it (don’t!), this can happen if you beat for too long or your kitchen is warm. The sweetener and cocoa powder will sink to the bottom if it melts, so it’s super important to avoid this.
- Use the right sweetener type. I can’t emphasize this enough! If you want a smooth low carb fudge without any crystals or grainy texture, you need Besti Powdered.
- Mix at low speed — just long enough to combine everything. If you crank it up too high or for too long, you’ll end up with air bubbles.
- Don’t have a hand mixer? You can try to stir carefully by hand, but I find it’s hard to incorporate everything evenly. Maybe if your butter is extremely soft. If you’re looking for a hand mixer, I love my lightweight mixer, which has a nice, low speed that this sugar free fudge recipe needs.
- Pick the right size container. It doesn’t have to be exactly like mine (this is the one I used), but don’t go too big. You’ll probably need a smaller one than you’d expect. If you don’t have a small enough one, I recommend doubling the recipe and using a loaf pan.
- Cut it right. Use a sharp knife and cut straight down—no seesawing, or it’ll crumble. To prevent sticking, rinse the knife between cuts and wipe it dry. If it still crumbles, the fudge is probably too cold and you can let it warm up at room temperature for a bit.
- Don’t leave it out too long. The texture of my keto fudge is best after about 5 minutes out of the refrigerator. If it comes completely to room temp, it starts to melt and is harder to eat. It’s more doable if you include the optional chocolate chips, though.
Flavors And Toppings
My recipe for keto fudge is easy to customize with add-ins and toppings! I’ve enjoyed these fun variations:
- Peanut Butter – Use a toothpick to swirl some peanut butter (mix with powdered Besti to your taste first) into the chocolate mixture before popping in the fridge. Or if you want peanut butter without the chocolate, make my keto peanut butter fudge.
- Rocky Road – Fold in chopped nuts (almonds, walnuts, or pecans) and bite-sized keto marshmallows. If you’re nut-free, pumpkin or sunflower seeds work great for that same crunch.
- Cookie Dough – Roll small balls of keto cookie dough and fold them into your bowl.
- Peppermint – For a festive vibe, stir in a teaspoon of peppermint extract.
- Caramel – My sugar free caramel gets firm in the fridge, so it’s perfect for drizzling over keto fudge before it sets.
- Sugar Free Sprinkles – Make them red and green for Christmas, or blue and white for Hanukkah.

Instructions
[ See step photos See my tips ]Tap on the times in the instructions to start a kitchen timer.
-
Line a 28 oz rectangular glass container (I used this meal prep container) with parchment paper, so that the parchment hangs out over the sides.
-
In a medium to large bowl, use a hand mixer at medium-low speed to beat the butter and Besti Powdered together, until fluffy.
-
Beat in the cocoa powder, vanilla, and sea salt.
-
Melt the chocolate chips in the microwave, or in a double boiler on the stovetop. Beat into the other ingredients in a bowl.
-
Adjust sweetener and salt to your taste. Do not overmix.
-
Transfer the mixture to the lined container. Smooth the top with a spatula or spoon. Sprinkle the top of the sugar-free fudge with sea salt flakes, if using, and press gently to secure.
-
Refrigerate the keto fudge for at least an hour, until solid.
-
Remove the fudge from the container using the edges of the parchment paper. Slice carefully into 15 pieces, 4 cuts the long way and 2 cuts the short way (see post above for my slicing tips).

0Instead of Besti Blend, will this recipe work if use honey or maple syrup? What happens if it doesn’t work well? Not a fan of monk fruit. Thank you so much for your reply!
Maya | Wholesome Yum
0Hi Melissa, No, sorry, I don’t recommend using a liquid sweetener because the fudge will not set. I know you mentioned you’re not a fan of monk fruit, but did you know most brands of monk fruit are over 99% erythritol? Check the ingredient list and you’ll notice erythritol is listed first, that’s why. If you haven’t tried Besti before, I hope you’ll consider it because it really is quite different from other brand labeled “monk fruit”.
Ruth Uttley
0Can you use plain allulose instead ofbthe monkfruit version in your recipes?
Maya | Wholesome Yum
0Hi Ruth, Yes, you’ll just need more of it.
Stuart
0Hi Maya. Besti products are difficult to get here in Canada without taking out a second mortgage. What do you recommend as alternatives, in order of compatibility? Thanks…
Maya | Wholesome Yum
0Hi Stuart, You can get Powdered Besti here, and the price is the same as in the USA. Unfortunately all the other sweeteners I’ve tried yield either a gritty result or bitter aftertaste.
Gina Perfetto
0If I have no chocolate chips….can I leave it out or should I add more cocoa?
Thank you so much
Maya | Wholesome Yum
0Hi Gina, I’m sorry, this recipe does require chocolate chips to get the right texture.
Debbie
0I have diabetes and so do some of my family members. I wish that these type of products were more affordable. It’s hard to eat healthy when a person lives on SS.
Maya | Wholesome Yum
0Hi Debbie, I agree with you, I wish healthier, clean ingredient products cost less! Unfortunately the processed stuff is much more mass produced and therefore cheaper. Hopefully as more people start to care about their wellness and buy more of these better products, the prices can come down. I certainly plan to pass that along for my Besti sweeteners if that happens! We do have 10% off with subscribe and save on powdered Besti sweetener here.
Laura
0I am so sad. It turned out like soup. I even re-read the instructions several times and read reviews to be sure.
I knew one cup of butter seemed like a LOT and it was. I didn’t see anybody say this.
Did I overlook the oven temperature and baking time? I went with 350 degrees and checked it after 20 minutes. It was bubbling and it didn’t seem like any extra time was going to firm this good looking recipe.
What did I do wrong? Can I salvage this?
Maya | Wholesome Yum
0Hi Laura, This fudge does not get baked at all, you got soup because you baked it. It goes in the fridge. Please read the instructions above carefully so you don’t miss a step next time. 🙂
Cathy
0Super creamy. I used butter and the melted chips. Thank you!
Maya | Wholesome Yum
0Thank you, Cathy! I’m glad you liked it!
Marjorie Heard
0Here in Canada we have Maple fudge. Would it be possible to use your WY Maple Syrup to flavor and if so how much? Thanks Maya
Ginny
0I know this is 2 years later, but you could use Maple extract instead of the vanilla extract she calls for in the recipe.
Maya | Wholesome Yum
0Hi Marjorie, I’m certain there’s a way to use my Wholesome Yum sugar-free maple syrup to make fudge, but unfortunately it would require testing a new recipe, since it’s liquid and would throw off the ratios in this recipe. I’ll put it on my list to experiment with — thank you for the suggestion!
Gail cooks
0What “sweetener” do you add in step 5 and how much do you add? The Besti was already added in step 2.
Maya | Wholesome Yum
0Hi Gail, It’s the same Besti powdered sweetener. You can just adjust it to your taste at that step if you need to.
Jennifer
0You can’t go wrong mixing butter and chocolate! So easy to whip up, and really hits the spot when I’m craving sweets. It’s also filling since it’s buttery. And the salt on top is the perfect touch. One of my keto sweet-treat go-to’s!
Andrea Morse
0I am making this fudge for the first time. Do I really need to use the parchment paper or can I butter the dish I am putting it in?
Thank you
Andrea
Maya | Wholesome Yum
0Hi Andrea, Yes, I recommend using parchment paper. The fudge is very difficult to remove without it.
D M Lundy
0I made this recipe, exactly as written, and it turned out exactly as stated it would. However, when it has chilled (overnight) and was cut into small squares to be served–there lies the rub in this recipe. I served it to my chocolate addicted wife, a couple of neighborhood friends, and I ate a piece–to the person we all agreed that it was rich chocolate flavor, smooth, (like real fudge); but, all of agreed that it was like eating a stick of flavored butter.
Maya | Wholesome Yum
0Sorry to hear this recipe didn’t meet your expectations. Did you use Besti when making the recipe? Maybe you would have preferred a little more cocoa powder?
Laura Drerup
0Hi, I have some cocoa butter & wondered how this might work in the fudge. Do you think it would make it firmer?
Thanks,
Laura
Maya | Wholesome Yum
0Hi Laura, Yes, I think that could work. That is essentially what the chocolate chips in the recipe do, so I would add it at the same time as those. Since cocoa butter is not sweet, you might need more sweetener to balance it. Please let me know how it goes if you try it!
Melissa Mobley
0This is, by far, the best fudge I have EVER had, and as a confirmed chocoholic, you can believe I’ve eaten hundreds of pounds of fudge in my lifetime. It has my two favorite things, butter and chocolate, and the only thing I don’t like about it is not being able to eat the whole pan! Beyond excellent!
Margaret
0What are the dimensions of the glass container you used, please? (The Amazon listing doesn’t provide dimensions.) Thanks very much!
Maya | Wholesome Yum
0Hi Margaret, This container is about 4×6 inches.
Curt Hawley
0Why unsalted butter? Salt is in the recipe, just use less?
Maya | Wholesome Yum
0Hi Curt, I use unsalted butter in most of my recipes because it lets me control the amount of salt to get just the right amount, rather than being locked into the amount that the butter has.
Deborha Packard
0This fudge recipe was a real hit with my whole family! No one guessed it was sugar free!!
jess
0This recipe is just as delicious as it is easy to make! thank you so much for sharing this amazing dessert recipe!
Gwendolyn
0Hello, was wondering if you could modify the recipe to make the fudge vanilla, or strawberry?
Maya | Wholesome Yum
0Hi Gwendolyn, I haven’t done this, but please let me know how it goes if you decide to experiment.
Journa Liz Ramirez
0My kids can’t get enough of this keto fudge! So rich, sweet and satisfying. Highly recommended!
Paula K
0Absolutely delicious and so easy to make! I am bringing to our NYE party!
Lori
0Can you use granular alluslose/monk fruit and grind, Do you need to add more?
Wholesome Yum D
0Hi Lori, Yes, You could grind granular Besti to make it powdered, and then you would want to follow the recipe as stated.
