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.

-
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).

0First of all, I’m so glad I found you! I love the keto recipes & ideas you’ve posted! Your posting this recipe right now is PERFECT timing for me. I’ve been reluctant to buy sugar-free chocolate because of how much it is & have been looking for recipes to make my own from cocoa powder. Your advice re not melting the fat, what type of powdered sweetener to use, & how to mix the sweetener w the UNmelted fat is exactly the info I needed!!! I wonder if cocoa butter might be good here??? 😀
Maya | Wholesome Yum
0Thank you so much, Carol! I hope you’ll love the fudge. I haven’t tried the cocoa butter option. My only concern would be whether you can get it soft enough to blend with the sweetener without melting – if you can, it should work!
Maria
0I can’t wait to try this recipe. Can you substitute the powdered erythritol for something else?
Thank you
Maria
Maya | Wholesome Yum
0Hi Maria, You can also use powdered monk fruit sweetener like this.
Pam
0Can you give the dimensions of the pan, please? Thanks. Anxious to give this a try, I miss my occasional fudge fix.
Maya | Wholesome Yum
0Hi Pam, This is the pan I used. Let me know if you have any issues with that link.
Kerri
0There are two pan sizes in the link. Do you use a 6”x4” pan or 6.25”x4.25”?
Maya | Wholesome Yum
0Hi Kerri, Sorry about the confusion – looks like the link changed after I posted it. I used a pan like this (and updated the links now).
Renee
0Hi Maya,
I’m excited to try this. You said we could use butter instead of the coconut oil. Would we use the same amount? So 1 cup butter instead of 1 cup of coconut oil? Thank you!
Maya | Wholesome Yum
0Hi Renee, Yes, the same amount of butter.
Tammy
0Love your recipes,thank you! What is the nutritional info with butter instead of coconut oil?
Maya | Wholesome Yum
0Thank you, Tammy! I don’t have exact nutrition info for substitutions, so you’d have to enter ingredients into an online calculator. But, I can tell you that it would be almost identical.
Pat Katz
