Ingredients You Need
Keto Fluffy Chocolate Mousse (3 Ingredients, 5 Minutes!) recipe
- Heavy cream – cold for maximum fluff
- Powdered sweetener – allulose or erythritol blend
- Unsweetened cocoa powder – natural or Dutch‑processed
Instructions How to Make the Best & Fluffiest Keto Chocolate Mousse
- Add the heavy cream and powdered sweetener to a large mixing bowl. Beat on medium‑low until it begins to thicken.
- Add the cocoa powder and continue beating until stiff peaks form.
- Spoon or pipe into serving glasses and garnish as desired. Serve immediately or chill briefly for extra fluff
Make Your 3 Ingredient Keto Chocolate Mousse Extra Pretty
- Pipe with a star tip for bakery‑style swirls
- Add grated dark chocolate or sugar‑free chocolate chips
- Top with fresh raspberries or strawberries
- Dust with extra cocoa for a dramatic finish
- Add a tiny pinch of espresso powder for deeper chocolate flavor
Storage & Tips for 3 Ingredient Low-Carb Chocolate Mousse Recipe
- Chill in the refrigerator for just a few minutes after preparing or serve immediately. This will keep your mousse from having that ‘deflated’ texture.
- When properly stored, it can last for 5 to 6 days in the fridge. Freezing not recommended.
- Don’t over whip the whipped cream. If you do you’ll end up with butter instead.
Variations
- Lighter chocolate: Reduce cocoa by 1 tablespoon.
- Cheesecake mousse: Beat 4–8 oz softened cream cheese first, then fold into the mousse.
- Dairy‑free: Use chilled coconut cream (only the thick part).
- Flavor twists: Add vanilla, chocolate extract, espresso powder, or orange zest.
- Smooth texture tip: Always use powdered sweetener — granulated sweeteners make mousse gritty.

Fresh FAQs for 3 Ingredient Keto Chocolate Mousse
Can I make this mousse ahead of time?
Yes — it keeps beautifully. Store it covered in the fridge for up to 2 days. The texture stays fluffy, but you can give it a quick whisk if it settles.
Why is my mousse grainy?
This happens when using granulated sweetener. Always use powdered sweetener for the smoothest, cloud‑like texture.
Can I use Dutch‑processed cocoa?
Absolutely. It gives a deeper, richer chocolate flavor. Natural cocoa works too — it just tastes lighter and more classic.

Yes! Use chilled coconut cream (the thick part only). It whips up beautifully and stays low‑carb.

Powdered allulose or powdered erythritol blends work great. Allulose gives the smoothest finish and no cooling effect.
Can I freeze this low-carb mousse?
You can — it turns into a soft, scoopable frozen mousse. Thaw slightly before serving for the best texture.

How Chocolate Wrappers Evolved Over the Years: A Quick Look
WowI I would have never thought of trying that! So glad it worked out for you Alesia! Woohoo!
I just left a comment on your pinned post. Loved this. I didn’t have cocoa powder so used chocolate flavored bone broth protein powder instead. Turned out awesome!
CJ thank you so much for trying the recipe and your lovely review! I appreciate it so much and so happy it was so delicious! The chocolate chip addition sounds yum!
I stirred in Lily’s sugar free chocolate chips, they’re small size, so they are delicious.
Plus, I used the sugar free confectioner’s sugar, no gritty texture.
Thank you for sharing this lovely recipe! What a flavorful dish – we all loved it! It is Simple and delicious. I could eat this each and every day for lunch. Also visit. https://kettlesboiler.com/best-whistling-tea-kettle/ .
That sounds amazing with the fresh cherries and jello! I’m going to have to give that a go! Thank you so much for trying it Marie and for your awesome review!!! xo
Thank you for this easy, delicious and versatile chocolate recipe that is so light, fluffy and tasty without using heavy cream cheese. I did add a small amount of vanilla, and as I mixed it, I added a little more cocoa and sweetner to get the exact flavor that I wanted. I cut up fresh cherries and added them. I made a parfait of this with cherry sugar-free Jello and it was so unbelievably delicious!
Hi Jaime! Yes you could use one of those and one of the biggest advantages of xylitol is that it measures 1:1 like sugar in terms of sweetness, so it should be the same. You could frost a cake with it, but keep it refrigerated since it is dairy-based. Hope you enjoy!
I can’t rate as I haven’t tried this yet (but it LOOKS amazing!!). However, I was wondering:
1) could one use granulated xylitol or erythritol sweetener (like Swerve or Truvia) and if so would the measurement change?
2) Could this hold up to being used to frost a cake?
Awesome! I did not know you could do that but cool to know Estella!! Thank you for the tip!
I used vanilla skinny syrup to sweeten and it came out awesome!
Yes definitely it will hold up Kristin! Enjoy!
Can you store this overnight? Will it hold up?
That’s so awesome that your daughter loved it as well! Thank you so much Shauwan for letting me know!! xo
LOVE this simple recipe. My 10 year old daughter who’s picky, enjoyed it as well.
I’m using Lakanto monk fruit sugar, granulated. 🙂 Thanks!
Are you using granular or confectioners sweetener? Thanks!
I’m so happy you enjoyed it Teri! Thank you so much!
OH MY CHOCOLATEY GOODNESS!!! Very rich but sooo good!!!
Yes you could Sue. Once you start getting the stiff peaks, add it in and taste test!
Could you use honey for the sweeetner?
I am obsessed!!!! So amazingly fantastic!!! My new go to Keto dessert!!! Came out perfect!! I used about 2 cups of heavy whipping cream, 3 small packets of Stevia (what I had in hand) and about a tbs of unsweetened cocoa. Wow!! Never thought it would be that easy!! I indulged bc I was ovulating (lol) and topped it with blueberries and 2 cherries! It was my first cheat night, in 3 weeks. I was weak but thank you so much!!!
Wow!! I just got done making this and I was tempted to stick my whole head in the mixing bowl to lick every last bit out! A few weeks ago I decided to cut added sugars from my diet because I got Covid and lost my taste and smell. Now that I have it back, I was really craving a chocolate dessert and boy did this hit the spot! This is also my first time using monk fruit sweetener and I’ll never use anything else. No aftertaste, just chocolate perfection! Thanks so much for the recipe!! 🙂
That is awesome to hear Karen! Thank you so much and yes guilt-free with a few bites is like heaven if you ask me! Happy New Year!!
Before recently starting Keto I could and did slam all forms of sweets uncontrollably. My sweet tooth was screaming for something. I made this recipe and it is ah-maz-ing. Although it honestly tastes so good it is so rich I could only have a few bites. I am so grateful for a guilt free treat!!
Well I screwed it up from the get go. Dumped the cocoa powder into the cream and realized I should not have. Nothing to loose except a little heavy cream so I dumped the monk fruit sweeter in and proceed to mix. Have to say it turned out ok. Added some raspberries and everyone chowed down. Thanks for a quick, easy, fast treat.
Hi Fay, this recipe makes 4 serving portions with the calories, etc in the recipe card. Is that what you were referring to?
Can’t wait to try this tonight
In case I may have missed it
What is the serving portion please.
Thanks Fay
That would be right. 2g fiber subtracted from carbs would make it 5 net carbs.
I’m so glad you enjoyed it Terri! Thank you so much for trying it!
This is absolutely decadent! I did add a little vanilla and in my opinion it made the taste even better!
Hi Kathy! I looks like 7 carbs to me for each serving. Hope you try it! xo
I see the nutritional info but would the bet carbs be 5?
The nutrition is at the bottom of the recipe and it’s calculated per serving. Hope that helps Candy! Thank you!
How many servings or nutrition per serving, Please!
unsweetened cocoa powder, not cocao. Sorry about that Marie!
Hi Kim,
Is cocoa used in this recipe or cacao? One is used in the ingredient list, the other in the instructions. Thanks.
That’s great to hear Janice! I’m so thrilled to hear!! Thank you so much! xo
I used the powdered monkfruit sweetener and it turned out very smooth. I didn’t use quite
1/3 c because it’s very sweet. Mine turned out great!
Tried making this and the flavor was spot on! Unfortunately, the sugar substitute (granulated monkfruit didnt dissolve all of the way and the texture was grainy. Any recommendations? Btw, the texture didnt stop me from eating it! 🙂
I just updated it in the nutritional part of the recipe. Thank you!! 🙂
Terri, I just updated it in the nutritional part of the recipe. Thank you!! Hope you enjoy! xo
Sitting here reading this going…. ‘Mmmmmmm!’ Hubby said, I like when you read something and say that!
BTW. What’s the stats on this? Like, carbs, fat, etc? Can I get a reading?
Do you have the nutritional info for this Mousse? Looks delish!
haha! I love it Catherine! Hope you enjoy it as much as we did! xo
This mousse is perfection, Kim!! So dreamy and fluffy, I can’t wait to make this-I’m hiding this one from my husband, all for me!
Thank you so much Katherine! xo
I loooooove chocolate mousse, Kim!! And love that this is low-carb. I wouldn’t be able to keep my hands off of this fluffy mound of deliciousness!
I love using the monkfruit sweetener as well. So glad you tried it Michelle! Thank you so much!!
Thank you so much Valentina! Those roses go perfectly with that mousse! 🙂
Not yet, but I’m going to try it for sure, it looks so tasty!! What recipe do you use?
This looks delish!! Have you tried the Artisan bread yet? I usually bake my own keto bread and wondered about the taste and texture.
YUMMY! And it’s so pretty! (Love those gorgeous roses in top image behind the mousse, too.) Pinning! 🙂 ~Valentina
This is delicious! I happened to have all of the ingredients in my pantry and fridge, so I whipped this up in 5 minutes, literally. I used monk fruit as stevia upsets my stomach. I will say that it’s quite rich, so I’ll make a little plain whipped cream to cut through the richness next time. Yum!
This looks so rich and creamy, I’m swooning!
