This Keto Mocha Mousse is a velvety cloud of rich chocolate and coffee. Each bite melts in your mouth and is guaranteed to satisfy all your chocolate cravings. While this elegant dessert tastes gourmet, it couldn’t be any easier to prepare at home! Unlike many mousse recipes, this recipe is simple and doesn’t require any cooking. This recipe can easily be prepared in less than 20 minutes.
It’s important to keep in mind that this mousse is best served after it has had several hours to set in the refrigerator. When making this mousse, I like to prepare it a few hours before making dinner. That way, the dessert is all done and you can focus on the main meal! If possible, I’d even recommend making it the night before. The extra time in the fridge seems to create the perfect, delicate texture.
Not a coffee fan? Not to fear! The instant coffee powder can easily be omitted to create a delicious chocolate mousse. I do recommend leaving in at least ½ tsp. of coffee powder in. Even just a little coffee powder goes a long way in creating a rich chocolate mousse without the strong coffee flavor.
So, what’s the secret to creating a low-carb mouse with the perfect texture? The key is folding in whipped cream. Lightly sweetened whipped cream is carefully folded into this mousse to create an irresistible, velvety texture. When folding in the whipped cream, try not to deflate any of the bubbles in the whipped cream. These bubbles are what will create the light texture in this mousse.
Combining chocolate with coffee brings out the best of both flavors. The coffee adds depth and complexity to the chocolate flavor and the chocolate provides rich sweetness. If you’re a chocolate and coffee lover, this mousse will become staple.

I have to say that this is the most delicious recipe for mousse! I have been trying different desserts on my Keto diet and this is the best! I have to say that it is almost better than those that are made with all the “normal” ingredients.
This looks amazing! Can I sub in liquid Stevia??
I think so! I don’t know exactly how much you would need.
I just made this recipe. It is delicious! However, there is a grainy crunchy texture to it. I think it’s from the erythritol (SP?) that I used. Any suggestions on how to fix that?
Hi Deborah, I hate when that happens! I’ve made this without it crystallizing on me, so sometimes it’s a bit of a mystery. There’s two things you can do. The easiest is to powder the erythritol using a spice grinder. You can also buy it “confectioners” style if you don’t want to grind it yourself. The other is to just make sure its warmed in a liquid. (Which probably wouldn’t work that well here.)
Thank you! I will look for the confectioner style. I’m new at this and don’t have a lot of time to play around with ingredients. This desert was great! It satisfied my sweet took and chocolate fix! 🙂
I actually liked the crystallizing in this recipe! Wanted to check in regarding nutrition values entered. It’s seems your count for raw cocoa powder is a bit low (mine is 60 cals per 2.5 tbsp, making it 96 for 4tbsp or 1/4 c). Same for sour cream. Usually it’s. 30 cals per tbsp. Total per serving came out to 443 cals. Thanks for the recipe!!
Hi Olga, the numbers for the cocoa and sour cream come from the USDA standard reference database. It might differ from the brand/style you’ve used.
Very delicious and smooooooth mousse! Surprised my boyfriend said that it was lighter than just whipping cream! Definitely will make it again! Love idea with instant coffee!
I just made this & it is delicious 😋 Thankyou so much for this recipe. I didn’t have any instant coffee so I put an espresso in & it still worked.
Can I make this using 100% dark chocolate and just erythrol (Swerve), no stevia? Any suggestions how I would adjust the recipe?
I’d add a few more tablespoons of the erythritol and powder it so it soaks up some of the liquid since there would be no cocoa powder. You may have a slightly less mousse-like texture though since the cocoa powder drives some of the moisture out and allows it to keep shape more.
I made this today and instead of coffee added liquid peppermint and liquid coconut for flavor, as the coffee is just too strong for me. I LOVE this recepie.
What a great idea!
I made an almond flour crust in glass pie plate, omitted the heavy cream step and voila! Mocha cheese cake. I garnished with crushed black walnuts.
cant find vanilla extract. can i use vanilla pod or essence? thanks
Yes, either should work in place of the extract.
This almost taste salty to me, I’m not sure what I did wrong? I think it’s the coffee. Any ideas why it taste like this?
The only thing I can think of is if you used salted butter it may have imparted a slightly salty taste. None of the other ingredients should really be adding a salt undertone.
That’s what I thought but, I checked and I didn’t. I think I put too much chocolate and too much coffee for my taste. Texture is great though. I’ll try making it again.
I hope you’re able to solve the issue and next time it comes out perfect for you. Let me know how it goes!
I made this last night and it is delicious. I divided it into 12 small cups as a quick “fat bomb” type snack. How long can this be stored in the fridge and still be fresh and can you freeze it? Thanks!
Awesome to hear! I’d say 7-10 days in the fridge. If you make them into fat bombs you should be able to freeze them, but they may not have the same consistency on defrosting.
