Rich, airy keto chocolate mousse made with heavy cream, cocoa powder, and powdered sweetener, plus optional vanilla and a pinch of salt. I whip it in one bowl in about 3 minutes. Serve right away or chill for 30 to 60 minutes for a firmer texture.
This is the chocolate mousse from my quick dessert video: heavy cream, cocoa powder, and powdered sweetener whipped in one bowl. I add vanilla and a pinch of salt to round out the chocolate flavor. There are no eggs to cook and no chocolate to melt.
The cream starts cold. I beat it just until it begins to thicken, then add the cocoa and sweetener before finishing the whipping. Adding the powders before the cream reaches stiff peaks gives you time to work them in without overbeating it.
The finished mousse is rich and airy, with the flavor of the cocoa you choose. Use unsweetened cocoa and a powdered sweetener. Granulated sweetener can leave grit in a dessert that never gets heated.
You can scoop it into four bowls and serve immediately, or chill for 30 to 60 minutes for a firmer texture. That optional chilling time is extra; the three minute estimate is for mixing with an electric mixer.
In the video, I also layer the mousse with a cooled cookie base for chocolate cream pie in a jar. For something simpler, add a few raspberries or a dusting of cocoa just before serving. If you'd like a different flavor, my peanut butter mousse has its own ingredient amounts, and cheesecake fluff uses cream cheese.
Toppings for chocolate mousse
A few berries, a dusting of cocoa, or some chocolate shavings add a finish to each bowl. Chopped nuts add crunch; a spoonful of whipped cream adds another soft layer.
Add toppings just before serving. They are not included in the recipe’s nutrition estimate, so account for the amounts and products you use.
Getting the texture right
Loose mousse: Start with cold heavy cream and whip to stiff peaks after adding the cocoa and sweetener. Milk, half-and-half, and warm cream will not behave the same way.
Powdery lumps: Sift lumpy cocoa and sweetener before adding them to the cream. Incorporate them while the cream is only slightly thickened.
Graininess: Granulated sweetener may leave grit, but overwhipped cream can also look grainy and begin separating. Stop at stiff peaks. A little cold cream folded in by hand may smooth mildly overwhipped cream; it will not necessarily rescue a mixture that has separated into butter.
Keep cocoa powder as the chocolate ingredient in this recipe. Melted chocolate adds different amounts of fat and sweetener and needs a different mixing method; warming the cream to make that swap conflicts with whipping it cold.
Make ahead and storage
For the best texture, make the mousse the day you plan to serve it or the day before. Cover the bowls and keep refrigerated at 40°F or below. Use leftovers within 3 to 4 days, or sooner if the cream’s package instructions require it.
You can freeze small portions for a firmer frozen dessert, but freezing and thawing may change the airy texture. Thaw in the refrigerator if you want it soft again.
For parties, keep portions refrigerated or in a cooler with ice packs until serving. Frozen mousse still needs to stay cold as it thaws. Do not leave it out for more than 2 hours, or 1 hour above 90°F.
How to make chocolate mousse
Start with cold cream. Beat it in a large bowl with an electric mixer until slightly thickened, before it holds stiff peaks.
Add the flavor. Sift in the cocoa and powdered sweetener if lumpy. Add the optional vanilla and a pinch of salt.
Finish whipping. Beat until stiff peaks hold their shape, then stop. Scoop into four portions. Serve now or refrigerate for 30 to 60 minutes for a firmer texture.
Use heavy whipping cream, not milk or half-and-half. Keep it cold throughout mixing. Powdered sweetener blends more smoothly than granulated; concentrated sweeteners do not replace the listed amount cup for cup.
Pour cold heavy cream into a large bowl and beat with an electric mixer until slightly thickened. Stop before stiff peaks form so there is room to mix in the remaining ingredients.
For this step
1 1/2 cups heavy cream
2
Add remaining ingredients
Add powdered sweetener, unsweetened cocoa powder, optional vanilla, and salt to the slightly thickened cream. Sift the powders first if lumpy. Beat until stiff peaks hold their shape, then stop before the mixture becomes grainy. Divide into four portions.
For this step
1/3 cup powdered sugar-free sweetener
1/3 cup cocoa powder, unsweetened
1 teaspoon vanilla extract (optional)
pinch of salt

Frequently Asked Questions
Can I use melted chocolate instead of cocoa powder?
Use cocoa powder for this recipe. Melted chocolate changes the fat, sweetness, and mixing requirements. Do not warm the cream and then expect it to whip like cold cream; choose a mousse recipe developed with melted chocolate for that version.
How many servings does it make?
Four portions, each one-quarter of the batch. The original approximate volume is 3/4 cup per portion, but the volume depends on how much air you whip in. Divide the finished batch evenly for the listed nutrition estimate.
Can I make it dairy free?
The recipe is written for heavy whipping cream. Coconut products vary in fat and stabilizers, so I cannot promise the same result as a direct swap. Use a mousse recipe developed for your chosen dairy free base.
Can I make it ahead?
Yes. Make it the day of serving or the day before and keep it covered in the refrigerator. Use leftovers within 3 to 4 days, or sooner if the cream’s package instructions require it. Add toppings just before serving.
Why is my mousse grainy?
Granulated sweetener, lumps of cocoa, and overwhipped cream can each cause a rough texture. Use powdered sweetener, sift lumpy powders, and add them before the cream reaches stiff peaks. Stop whipping once the finished mousse holds its shape.
What sweetener should I use?
Use a powdered sugar substitute with a sweetness level suitable for the listed amount. Check the package: concentrated monk fruit or stevia is not interchangeable cup for cup with a powdered blend. Different sweeteners can change the taste and texture.
Can I make it without an electric mixer?
A hand whisk can whip cold cream, but it takes more effort and longer than the three minute estimate. Use a large bowl and stop when the finished mixture holds stiff peaks. The timing in the recipe is for an electric mixer.
Does it need to chill before serving?
No. You can serve it as soon as it holds stiff peaks. The optional 30 to 60 minute chill gives a firmer texture and is extra time beyond the mixing estimate. Keep the mousse refrigerated until serving.
I have made this twice now and absolutely love it. I thought chocolate dessert was off my menu since I went keto but this hits the spot and tickles my chocolate taste buds. I agree that the chocolate flavour deepens the day after. Definitely worth the wait if you can hold yourself back.
I figured something this quick would skimp on flavor. It doesn’t. Two things worth knowing: start with two-thirds of the sweetener and taste first, because brands vary a lot. First batch I went too heavy, second one I got it right.
Amanda, go ahead and make it the night before. Mine holds its texture in the fridge for a good four days, and I actually like it better on day two once the cocoa settles in. Just cover it tight so it doesn’t pick up fridge smells.
3.1 carbs per serving. That’s what got me to try it. Four batches in, it’s staying in the rotation, but the ratio runs sweet as written. Been dropping the sweetener a tablespoon and bumping the cocoa. That’s the version I’ll keep making.
Sweetness varies by product, especially when a package is a blend rather than pure erythritol or allulose. Check its label and adjust to your taste before the mousse is fully whipped. Use powdered sweetener for a smoother texture.
Mousse always seemed like it needed an actual pastry degree, so three ingredients and a hand mixer was kind of shocking. Beating the cream before the cocoa makes sense now that I know, but I was guessing the whole time. My peaks ended up somewhere in the medium range and the thing still held overnight, which honestly felt like more of a win than it should. Four stars because I think real stiff peaks would take this somewhere else entirely, but even my chaotic first attempt had that deep cocoa thing without the fake sweetness you usually get with keto desserts. 3.1 net carbs. Wild.
Making this for a pool party next weekend for about 12 people, so I’ll be tripling the batch. Does the heavy cream still whip up fine in a bigger amount, or should I just do two separate bowls?
Tried blooming the cocoa powder in a tablespoon of hot espresso before folding it into the whipped cream and the difference is unreal. Not coffee-flavored at all, just deeper and more intense, like the chocolate actually woke up. I’m on batch six now and this version replaced the original for me. Worth the extra minute if you have espresso around.
Batch six and you’re blooming the cocoa now. I add espresso powder dry, but the liquid bloom makes more sense – actually dissolves everything before the cream hits it. Stealing this.
My sister is visiting this weekend and she’s been dairy-free for a year, so I want to make this for her. She loves chocolate mousse. Will coconut cream whip up to the same consistency, or does it need something extra to hold the texture?
Coconut cream varies by brand and may whip and set differently from dairy cream. I cannot promise a direct replacement here. Use a mousse recipe developed for coconut cream if you need a dairy free dessert.
Every keto mousse I’ve tried had this hollow sweetness, nothing behind it. The cocoa ratio here actually tastes like chocolate. Two batches in, I’ve stopped looking.
Sift the cocoa powder before adding it. Found out the hard way that skipping this step leaves little bitter clumps throughout, and no amount of mixing fixes it after the fact. Takes 30 seconds and the texture goes from fine to actually silky.
Sifting is helpful for lumpy cocoa. Add it after the cold cream is slightly thickened, as in the recipe, then finish whipping to stiff peaks. Avoid whipping the cream fully before adding the powders.
Triple batch every Sunday, portioned into little jars. The four-serving yield is laughably small once you realize how fast you’ll go through it. What I didn’t expect is how much better it gets by Wednesday. The cocoa deepens into something almost fudgy. I think about that jar all day.
My sister is staying this weekend and she’s lactose intolerant, so I’m wondering if coconut cream would work here instead of heavy cream. I’ve done the swap in other whipped cream recipes. Sometimes it comes out beautifully, sometimes a little grainy depending on the brand. Would the cocoa powder affect how well it holds once it’s folded in, or would it basically behave the same way?
Coconut cream varies by brand and may whip and set differently from dairy cream. I cannot promise a direct replacement here. Use a mousse recipe developed for coconut cream if you need a dairy free dessert.
I’ve tried a few keto chocolate mousse recipes and they mostly end up tasting like cocoa-flavored whipped cream. Fine, but not what I’m after. This one is denser, actually holds its shape. Something about the cocoa-to-cream ratio works here; it doesn’t taste like a workaround. Already making it again this weekend.
The cocoa does the heavy lifting on texture. Most recipes dial it back because it can deflate the cream if you’re not careful about whipping to stiff peaks first. Once you nail that part the density just follows.
My 10-year-old has radar for keto desserts and usually fakes being full after one bite. He ate almost the entire bowl while I was still setting the table, then came back asking where the chocolate stuff was. When I pointed at the empty bowl he genuinely looked upset. No graininess, nothing to tip him off. The cocoa powder just disappears into thick, cold mousse that he treated like it was from somewhere he’d want to go back to. I’ve made it three times in the last few weeks and started portioning it into individual cups before dinner so I actually get my share. He’s already asked if we can have it this Sunday.
Came back looking for the chocolate stuff and actually upset it was gone. Pre-portioning is the only way you keep your serving once they know about it.
For this recipe, whip the cold cream only until slightly thickened, then add the cocoa and powdered sweetener. Finish whipping everything together to stiff peaks. Adding the powders after the cream is already fully whipped can make it harder to mix them in without overbeating.
So glad you enjoyed the recipe. I need to try orange exact. I love the combination of orange and chocolate too. Of course, share on Facebook! Thank you!
