Look no further for the perfect keto chocolate frosting. Smooth and creamy, with rich chocolate flavour. This is the best recipe for all your low carb cakes, cupcakes, cookies, and brownies!
Fake it til you make it, as they say. And to make this amazingly delicious keto chocolate frosting, you’re going to have to fake it a bit, my friends! It’s not a true buttercream but it acts like one and it tastes like one. Keep reading to find out the secret!
And if you’re looking for perfect keto vanilla buttercream, I’ve got that too!
There is something you should know about me. I am a total faker and I am okay with that. I have accepted my fakery with aplomb and you should too. Because sometimes faking it gets you exactly where you want to be.
Now of course I am not talking about pretending I went to Harvard or saying that I am a close cousin to Queen Elizabeth. (As far as I know, I am exactly 30 millionth in line for the throne…pretty much all of England and Canada would have to die before I was your royal highness).
But I do fake it til I make it when it comes to low carb cooking and baking, and that’s what I did with this low carb chocolate frosting. And although I know some naysayer will inevitably come along and say it’s not a true buttercream, I say don’t be a hater. And don’t bother to give me a hard time about it, you will not ruffle my feathers. I know what I am about.
We get kind of used to faking it in this low carb diet of ours. We have to, if we want to enjoy some of the same foods we used to love.
So zucchini and cucumber and eggplant become noodles, cauliflower becomes potatoes and rice, and pork rinds become rice crisps (I got a hater comment on my low carb Scotcheroos which I thought was absolutely hilarious!).
Faking it comes naturally to me now, and I think as long as I can achieve my ultimate goal, which is the best taste and consistency in one of my keto recipes, I don’t care what I have to do. It’s all about the food, people!
The Secret to Keto Chocolate Frosting
And so the secret to perfect keto chocolate frosting is…cream cheese. Gasp! No really, this is something I’ve known for a while now and I am passing this secret bit of low carb wizardry on to you.
Why does cream cheese help so much in a low carb frosting? Because it gives the frosting structure without having to use copious amounts of powdered sweetener.
Think about it…a traditional buttercream frosting takes ridiculous amounts of powdered sugar. Take this gorgeous vanilla buttercream from Sally’s Baking Addiction, for example. It’s perfect but it also takes 4 to 5 cups of sugar, just to be able to be a proper spreadable and pipe-able consistency.
While I could do something similar with powdered Swerve, I just don’t want to. Here’s why:
1. My tastes have changed and I find frosting, even low carb frosting, much too sweet.
2. Low carb sweeteners are expensive! Who wants to pay $25 just to make enough frosting for one cake?
So a few ounces of properly softened cream cheese will give your low carb chocolate frosting a smooth consistency…unlike a some of the lumpy, clumpy frostings you see on many low carb cakes! Ugh!
Now, don’t try to tell me this is a low carb cream cheese frosting. It’s not and nothing you say can convince me otherwise. I love cream cheese frosting but it has a significant tanginess from the cream cheese and this keto chocolate buttercream does not.
All that the few ounces of cream cheese do is give it some structure so you don’t have to keep adding powdered sweetener. Instead, you simply get the best low carb chocolate buttercream around. Rich, smooth, chocolate-y, all without spending a small fortune on sweetener.
So the only question is…what are you going to put it on? How about my Classic Low Carb Chocolate Cupcakes? They are a match made in heaven!

Look no further for the perfect keto chocolate buttercream frosting. This is the best recipe for all your low carb cakes, cupcakes, cookies, and brownies!
- 2 ounces unsweetened chocolate chopped
- 1 tbsp coconut oil
- 1/2 cup butter softened
- 3 ounces cream cheese softened
- 2/3 cup powdered Swerve Sweetener
- 2 tbsp cocoa powder
- 1/2 tsp vanilla extract
- 1/2 cup heavy cream room temperature (give or take a few tablespoons)
-
In a medium microwave-safe bowl, combine the chocolate and coconut oil. Melt in 30 second increments, stirring in between until smooth. Alternatively, you can melt the chocolate and coconut oil together in a heat-proof bowl set over a pan of barely simmering water. Set aside to cool to lukewarm.
-
In a large bowl, beat the butter and cream cheese together until smooth. Beat in the powdered sweetener and the cocoa powder until well combined.
-
Add the chocolate and vanilla extract and beat until smooth. The mixture will be very thick at this point.
-
Add the cream a few tablespoons at a time until a spreadable consistency is achieved. (How much cream you need depends on the other ingredients...certain brands of cream cheese and cocoa powder have more fillers and fiber, which thicken the frosting and require more cream).
This makes enough frosting for 12 cupcakes or a single layer cake. You may need to do 1.5 to 2x the recipe for larger cakes.
Brenda Cash says
What? Someone is hating om my favorite Sotcheroos? That’s crazy talk. I have made them every week since you posted them. A big piece is my reward for making it to the end of the day. Oh yeah, this frosting looks delis too!!
Rita Rosentreader says
Does this freeze well? The recipes are large enough that for one person I need to be able to freeze them.
Carolyn says
Yup, I have frozen this…I had too much leftover one time and so I froze it. Then I defrosted it and used it for cookies.
Jan says
Great idea‼️
Ang says
This came out rich and delicious! Thank you!
BRENDA KENNEY says
I absolutely love reading and using the recipes from your posts!! Keep up the great work for all of us. So appreciated!!
Carolyn says
Thanks, Brenda!
Candace @ Cabot says
In a word…brilliant. OK, one more word…delicious! Keep ’em coming!
Susan Duquenne says
Absolutely love your website and have had the best luck with so many of your recipes. I just made the chocolate buttercream frosting and I didn’t have powdered Swerve so I put some granulated Erythritol in my coffee bean grinder and pulsed it quite awhile. (I’ve done this before). My frosting still turned out a bit grainy. Any suggestions??
Carolyn says
Yup… get some powdered Swerve or other powdered erythritol. Sorry but you simply can’t make it fine enough at home.
Michele Barker says
Coffee Grinder makes perfect powdered sweetener. 🙂
Carolyn says
Actually…. it does not. It’s pretty good but you will never powder it finely enough for a frosting and will still have some residual grittiness.
Susan says
Do I actually need to put it on something, besides a spoon? I remember eating half a jar of frosting and seems to me this would take me back to that yumminess ?
Carolyn says
I won’t tell if you won’t!
Dina says
Hey, it’s technically a fat bomb so it could totally fit into your macros!
miranda says
I was just thinkng about that, it sounds delicious a a dessert with a little buttercreamcookie or just like it is.
Christine says
This sounds delicious, can I use adavodo oil instead of coconut oil?
Thanks for all your incredible recipes .
Betsy Stokes says
Hi, Carolyn. I’m curious if you have experimented at all with using polydextrose as an ingredient? I was looking at a recipe for keto frozen yogurt (from another cookbook), and it called for it. I think it affects texture? I wonder how it would do in frostings like this? If you have a moment, I’d appreciate any thoughts. Thank you!
Karen says
Hold Up. You have a recipe for Scotcharoos?!! How’d I MISS that? So finding that recipe and making them. ASAP. They were my absolute fave before going lc.
Will make them. that is, as soon as I make this delicious-looking buttercream frosting to go with your chocolate cupcakes. Brother-in-law’s birthday tomorrow, so — perfect timing! (I always make the fam lc treats from your site and no one EVER knows the difference.) I’m a faker, too. =))
Carolyn says
So glad to hear it! Yep, the scotcheroos are a huge hit!
Dina says
This looks like an amazing solution to my usual LC buttercream dilemma– love frosting, but the LC versions are often too sweet, and very expensive to make.
Since I am a chocolate hater (yes, I know *sigh*) I may experiment with 2 ounces of cocoa butter, since the chocolate seems integral to the structure and texture.
Carolyn says
It actually works. I have a white chocolate buttercream recipe…use the search box for my white chocolate cranberry cake and you will find it!
Michelle says
I’m glad I checked the comments. I made this version for my birthday and it turned out awesome. I was pondering what it would take to make a white version in case I wanted to get fancy with decorating at some point (colored frosting). Since I rarely use sweeteners, because this sort of thing is a rare treat, I didn’t really want to pop for another sweetener (the BochaSweet) to make the vanilla frosting you linked above. This white chocolate version is a better solution for me. Especially since I already have cacao butter. 😊 Thanks!
Scott Miller says
Carolyn, there must not be a search box on the mobile version, I can’t find it.
Carolyn says
If you’re on mobile, click the three little lines right at the top, which brings up a menu. The search box is at the bottom of the menu. That way, you can find what you’re looking for.
Lara says
This looks amazing!
Elizabeth Benge says
Do you have a suggestion on what to use instead of the coconut oil? I’m highly allergic to coconut.
Carolyn says
Just use butter.
Larina says
This is DIVINE! Thank you!
Carolyn says
Glad you like it!
Julie says
Fantastic keto chocolate frosting. Just made it, and I’m pleasantly surprised. The consistency is lovely. I was worried about the coconut oil because I’m not a huge fan of the flavor, but you can barely taste it. Thanks!
Carolyn says
Yes, that coconut oil is just to help the chocolate melt.
Trisha says
This is amazing!!! I have been on the keto diet since October and this is by far the best sweet thing I have made. Thanks for the great recipe!
Jenn says
Could you substitute almond milk for whipping cream? Or would you need to add something else for stability?
Carolyn says
No, it would not be thick enough. Or creamy enough.
Nicole Foster says
Made this today and love it! It was the perfect amount of frosting for each cupcake and was wonderful with your chocolate cupcake recipe.
Yvonne Greenawalt says
Can I substitute cocoa for the baking chocolate?
Carolyn says
No, that would change the consistency a lot. Google how to replace baking chocolate with cocoa powder and you will see that you also have to add some butter or oil to make up the difference.
Chrissy says
This is the BEST Keto frosting that I have tried so far!
Karen Johansen says
My ALL TIME Favorite!
Nadia Davis says
This is my first time ever commenting on a blog recipe but I’m coming out to say this was amaaaaaazing. I used it to top my husband’s birthday cake. Im so glad we can celebrate and still feel good afterwards. Thank you thank you thank you!
Carolyn says
I am so glad, Nadia. Happy birthday to your husband!
Kourt says
With recipes like this I could be low carb FOREVER! I used this for my daughter’s birthday cake and it was so delicious! Thank you!
Kat says
So good! Love that it’s not overly sweet.
Does it need to be refrigerated? Made it and cupcakes but want to add to the cupcakes as they’re eaten, rather than frost them first. Wondering how to store the frosting.
Thanks!!
Carolyn says
Refrigerate until needed, but you will need to let it come to room temp before frosting.
Danielle says
Could I use splenda instead of the powdered whatchamacallit? First low carb baking attempt!
Carolyn says
No, I do not recommend splenda here as your buttercream will not hold up well and will be awfully bitter.
JOELIE says
Could I use powdered stevia instead of swerve? Love the idea of how this is low carb.
Carolyn says
I don’t think it will do well. What kind of powdered stevia do you have?
Erica says
I made this today and it was good!! I’m going to keep in my fridge and have a spoonful to curb sugar cravings. I did make my own powdered sweetener by blending corn starch and granulated great value sweetener in a food processor. We don’t have anywhere around us that sells powdered sweetener. It has a little aftertaste, but that keeps me from overindulging and I don’t have to order anything special online. (Cornstarch adds a few extra carbs). Thanks for posting!!
Carolyn says
Great ingenuity!
Patricia says
Can I use the normal swerve sugar replacement and not the powdered one? Or alternatively I have the strive drops?
Carolyn says
No to both of those. A buttercream needs a powdered sweetener for structure and taste. Granular would be very gritty and stevia drops wouldn’t give it any structure.
DeAnna says
You could put the granulated Swerve sweetner in the blender til its a powdery consistency. Wouldn’t that work Carolyn? LOVE your recipes Carolyn. Keepem coming…. 🙂
Carolyn says
No, it really is impossible to get it as fine as the commercial version so it won’t be a great frosting.
Kristen says
Hi Carolyn,
I’m making a keto cake and your delicious-looking frosting a couple of days in advance of a birthday. In your opinion, is it better to frost the cake, refrigerate the whole thing, and then leave at room temp for a few hours before serving, or should I frost right before the party?
Carolyn says
I would frost right before the party. No matter what you do, frostings made with erythritol tend to recrystallize so it will be best when totally fresh.
Amy says
Does this need to be refrigerated? If I put this on brownies, I then need to refrigerate the brownies. Sorry if this is a silly question.
Carolyn says
Yep. Anything with frosting should be refrigerated (although it’s probably okay on the counter for one day…)
Kate says
Thank you for sharing a delicious recipe. Made it just as is, using stevia-sweetened chocolate chips for the 2 ounces of chocolate. Yummy!
Vickie says
Made this today and its hard not to eat it by the spoonful!
Asia says
This is perfect! My husband’s Birthday is coming up and my husband does not like cream cheese frosting at all and he has never liked the buttery taste that comes with a lot of home made butter cream frostings but this is a perfect blend of everything! Chocolate, creamy, goodness! Yum!
Thank you!
Shauna says
OMG! This is AMAZING!!!! There is no way the “real” stuff could taste better!! Your Type1 follower appreciates this more than you know!
Carolyn says
Thanks, Shauna!
Angela Matota says
This frosting was a perfect for my cupcakes! It turned out fluffy and chocolatey 😋 thank you so much for this recipe, I am sure I will make it again!
Charlotte says
The heavy cream added to the mixture at the end is supposed to be added as it is or whipped?
Carolyn says
If it needed to be whipped, I would specify that and walk you through that part. So as is.
Charlotte says
Thank you so much, I am making it tomorrow for my boyfriend’s birthday so I need it to be perfect❤
Gina Marie says
The Best! There is nothing else to say, but that this is the BEST FROSTING EVER!
Cathy Williams says
Oh Yeah! These are fat bombs. I’ll save the cupcake carbs and omit the cream for a denser texture … so I can have more bombs. You’re a genius! Thanks sooooo much …
Cindee says
So I made your ultimate brownies but I was craving a icing for my brownies. Also want my non keto hubby and kid to enjoy them as well. And I stumble on this recipe!!? AMAZING! You are so right about all that sugar in an original recipe of icing sugar, I hated that as well.
Only question now is…my boys love vanilla everything, do you also have an amazing vanilla buttercream icing? And do you happen to have a recipe for those soft sugar cookies…you know the ones…you walk into Wal Mart and they have those soft iced cookies…my son isn’t keto but he has to have gluten free foods and he sure misses those cookies.
Tall order I know, but everything I have tried from you has NOT disappointed, I had to ask😀
Carolyn says
It’s a perfect combo!
Michele Barker says
This was a huge hit in our home! My husband wanted to lick the beaters and the bowl, and the spoon! lol
Thank you so much for sharing the recipe!
Kind Regards
Michele
Carolyn says
So glad you liked it!
Ashley says
I just found this recipe and I cannot WAIT to try it! My son has type one diabetes so I was trying to find something that he could have (and would like!) and it seemed impossible until now! So thank you! His birthday will be so special thanks to your recipe.
Carolyn says
I am so glad to hear it. It’s tough on a kiddo not to enjoy a good cake on his birthday!
AM says
Has anyone tried using allulose instead of erythritol?
Carolyn says
I don’t believe that there is a powdered version of allulose.
Maitri says
Fantastic frosting recipe! Moist, thick and creamy without being sticky or overly sweet. I powdered by own erithrytol and the texture was perfectly smooth. Any chance you can create a keto chocolate cake that uses a little coconut flour to reduce the grittiness of almond flour and adds sour cream to increase moisture? Also do you recommend a water bath for keto cakes to improve moisture? Thank you for the advice!
Carolyn says
Have you searched my blog for keto chocolate cake? My chocolate cupcakes are perfect. And no, a water bath is unnecessary.
Pam says
Would this work as a filling for Keto cream puffs?
Carolyn says
Sure!
Jaymie says
Very bitter tasting – what am I doing wrong??
Carolyn says
What sweetener did you use?
STACEY ROYLE says
I bake a lot. This is best chocolate keto frosting I have made,least gritty, best mouth feel due to the cream cheese and whipping cream. It is similar to a whipped cream cheese frosting I make for wedding cakes. Excellent recipe! Thank you!
Carolyn says
So glad to hear it!
Tess says
Oh My God, I never thought I could eve enjoy chocolate frosting on Keto. I have tried so many other recipes and finally found a recipe like this. It has a mousse like texture and would be awesome on chocolate cake. Thank you so much for this awesome recipe.I am in heaven!!!
Carolyn says
So glad you liked it!
Anne says
I’ve been making chocolate frosting with icing sugar, butter, vanilla cream and cocoa since I was 4 years old. I know how it works. The only difference here is a Swerve granulated sugar and cream cheese But I’ve made this twice today, and it split both times. It’s very tasty, but it doesn’t look or feel like frosting should. Any clues on what might have gone wrong?
Carolyn says
Hmmmm, tell me what brand of chocolate you are using? Or the cocoa powder. Could be that, maybe. Hard to say, but I have made this without issue more times than I can count!
Anne says
Thanks for responding. I used bakers unsweetened chocolate, and Rodel cocoa powder. Both products I’ve been using forever in icing. It tasted fine, but the texture was off. I’m going to try it again today. (another birthday), and I’ll see what happens.
Anne says
Well, sorry to cause you concern. I made this again today, and it worked just as I expected it should. Normal creamy texture. I have no idea what went wrong two weeks ago, but it’s clearly not a problem with the recipe… Just some sort of user error.
Carolyn says
Rodelle is fine. Baker’s could be the issue. I’ve had plenty of trouble with them, it’s much more prone to seizing. Ghirardelli works well, as do even pricier brands like Guittard and Scharffenberger.
Pia Lee says
I just made this and it was so good! I used Lillys chocolate chips for the chocolate part and Hersheys cocoa for the powder stuff. I put it all in a gallon ziploc back and generously frosted 24 cupcakes. So good! Its very VERY rich, I regret licking the bowl because now I have to wait to taste it on a cupcake. Thank you!
stassi says
can i use jaggery for the sweetener?
Carolyn says
No idea since I don’t use it. You will have to experiment.
AngelaK says
Do you happen to have a VANILLA buttercream recipe?? Hoping to make some keto cookie “doozies” for myself to enjoy during my daughter’s bday party this weekend, and prefer vanilla frosting over chocolate! This does look delicious, though!!! <3

Seriously so good! Taste better than the chocolate buttercream frosting from my favorite bakery!
