Chocolate Mousse Cake
This chocolate mousse cake is rich, creamy, and surprisingly easy to make with a soft chocolate brownie base, silky chocolate mousse, and a glossy chocolate glaze. It looks like a bakery-style dessert but uses simple ingredients and no complicated pastry techniques. Perfect for birthdays, dinner parties, or whenever you need an impressive make-ahead chocolate dessert.
Back when I had my cake business, chocolate mousse cakes always looked so elegant in the display case, but honestly, most of the traditional recipes were far too complicated for home bakers. Layers, inserts, mirror glazes, thermometers, and endless bowls… beautiful, yes — practical, not always.
Over the years, I realized people don’t really want a stressful chocolate mousse cake. They want something rich, creamy, soft, and luxurious that still feels achievable in a normal kitchen. This version became my favorite because it keeps all the beautiful texture and elegance without the complicated pastry-school steps.
And honestly? The combination of soft brownie, creamy mousse, and glossy chocolate glaze is hard to beat.

- Powdered sugar – Sweetens and keeps the mousse smooth.

Step-By-Step: Chocolate Mousse Cake
Prepare The Pan
Line the bottom of a 9-inch springform pan with parchment paper. Lightly grease the sides.
Preheat the oven to 350°F / 175°C.
Make The Brownie Base
Melt the butter and chocolate together in a microwave-safe bowl until smooth. Add the brown sugar and mix well. Add the eggs and vanilla extract, mixing until combined.
Stir in the flour, cocoa powder, espresso powder, and salt until just combined.
Pour the batter into the prepared pan and spread evenly.
Bake for 18 to 22 minutes until the edges are set, and the center still has moist crumbs. Cool completely before adding the mousse.
Make The Chocolate Mousse
Melt the chocolate in a microwave-safe bowl and let it cool slightly.
In a large bowl, whip the mascarpone, powdered sugar, vanilla, and salt until smooth.
Add the melted chocolate and mix until combined.
In another bowl, whip the heavy cream to soft peaks.
Fold the whipped cream gently into the chocolate mixture until smooth and airy.
Spread the mousse evenly over the cooled brownie base.
Chill for at least 6 hours or overnight.
Make The Soft Chocolate Glaze
Melt the chocolate gently until smooth.
Stir in the honey and oil until glossy and silky.
Let the glaze cool slightly until just barely warm and pourable.
Pour over the chilled mousse cake and gently tilt the pan so the glaze spreads evenly.
Return the cake to the fridge for at least 1 hour.
Decorate The Cake
Sprinkle lightly with flaky sea salt.
For a simple, elegant finish, place chocolate pieces or chocolate wafers around the top edge of the cake before serving.
Tips For Success
- Use 55% to 60% chocolate for the softest texture.
- Do not overbake the brownie base, or it will become firm once chilled.
- Whip the cream only to soft peaks for a silky mousse texture.
- Let the glaze cool slightly before pouring so it doesn’t melt the mousse.
- Chill overnight for the cleanest slices.

Hey there! I’m excited to make this recipe! I notice that there is no gelatin in this recipe. Will it set? I always thought a mousse has gelatin.
Thanks!
Hey Lis, No, there is no need for gelatin in this mousse – the chocolate and cream cheese with whipped cream work perfectly well to stabilize each other. Trust me, this one sets well and stays wonderfully firm for more than 48 hours in the fridge.
Veena,
Thanks so much for the reply! I ended up following the link the recipe on another page and figured it out. I think I should have whipped more air into my cream because the mousse didn’t have quite the volume of yours, but it was delicious anyway. The cake is GORGEOUS and unbelievably rich. My 6 year old said, “this is better than the best cake ever!”
Thank you, Lisa. Happy the mousse turned out wonderful. Aww so happy to hear what your six-year-old said. Of course, it the best cake ever because his mom made it. Thanks for the feedback.
Hi Veena,
Thanks for the recipe. I loved making it. I used your eggless chocolate cake for the base instead of brownies. I was afraid it would soak up the mousse but it did not. Next time I will soak the bottom with some chocolate milk. But, this was so tasty. Thanks
Hey Sunita. Thank you so much. Yes, the chocolate mousse works well with the eggless chocolate cake, but it’s quite moist on its own.
Thank you for the quick response. Appreciate your suggestions
Veena, I made the chocolate mousse per your recipe, and it was the best chocolate mousse cake ever! Thank you so much
Hey Karen, thank you so much for the lovely feedback.
Your recipe is so detailed and easy to follow and the video was incredibly helpful. The flavor was spot on and great! One question my store was out of whipping cream and I used heavy cream and I felt my whipped cream (and consequent mousse) wasn’t as voluminous. Does this sound right?
Thank you Cj. Happy to hear you had success with this recipe. Heavy whipping cream should have a good volume but even with soft peaks it should set easily. The gelatin takes care of that.
This looks wonderful! I’d like to try it for my father’s upcoming 85th birthday party. Do you use unsweetened chocolate for the brownie layer? I assume so, because you’re adding sugar, but just want to double-check. Many thanks! – Lisa
Thank you Lisa. I used dark chocolate – usually 65 to 70% dark chocolate. You can reduce the sugar in the torte if you want it less sweet. This was just right. Thanks
Just finished making this, came out perfectly! I made it red and white for the holidays. It has a candy cane effect to it. ? Thank you so much for posting! You are amazing!!
Thank you so much Shannon. So happy to hear your feedback. A red and white Christmas versions sounds so pretty. Do tag me when you share on any social media. I’m most in the username veenaazmanov on my Social Media Networks. Thanks
