The easiest way to wow a crowd is with anything that involves chocolate mousse. This is why I love this Chocolate Mousse Cake Recipe. It’s decadent, a bit mysterious and oh so divine! It’s really easier to make than you might think and in my video below I’ll give you all my tips!
What is chocolate mousse cake?
A Chocolate Mousse Cake is essentially a basic chocolate mousse recipe, poured into a crust, and set inside the fridge for several hours to be chilled. Mousse + Cake=The best of both worlds! Just be sure to plan ahead and allow enough time to refrigerate it, since it does take at least 4 hours to set up.
STEP 1: Make The Crust
How do you make a chocolate wafer crust?
A chocolate wafer crust is super simple to make with a package of these Famous Wafer Cookies. These cookies can sometimes be hard to find outside of “Ice Cream Season” so I usually just buy them online in a pack of 2. (this link goes to Amazon where I am an affiliate partner)
Just whirl up a full package of the cookies in your food processor until fine crumbs form, then add melted butter until a coarse meal forms that sticks between your fingers when you pinch it.
Fit into your cheesecake pan, tightening the sides with a measuring cup and then bake! (full recipe is below)
STEP 2: MAKE THE FILLING
You’ll melt bittersweet chocolate and butter in a microwave safe bowl at :30 increments.
Then you’ll add the egg yolks, sugar and vanilla and a rich chocolate mixture will form. You’ll set that aside.
Then you’ll whip your egg whites until a stiff peak forms.
Fold in these egg whites into the chocolate mixture. A little at a time, lightening the dense chocolate mixture with each addition of egg whites.
Once your mixture has lightened it will be easy to pour into your cheesecake pan.
At this stage you can smooth out the top with a spatula or leave the soft peaks.
Can you make chocolate mousse cake ahead of time?
Yes! You can definitely make a chocolate mousse cake ahead of time. In fact, I think it’s even better if you can make it a day ahead. That way it will have the time to really set up, which makes it easier to slice.
I even add the whipped cream on top too, so that it too will cut cleanly.
STEP #3: Garnish with Chocolate Curls
How do you make chocolate curls?
There are a couple ways you can make chocolate curls for this recipe. You can either peel the chocolate with a potato peeler for small curls.
Or for larger more impressive curls, melt some dark chocolate in the microwave, then pour it into a frozen baking sheet that you have placed in the freezer for a few minutes until cold, and flipped over.
Smooth the chocolate on the pan with an offset spatula until a thin layer forms.
Allow the chocolate to set, and then push it into curls with a bench scraper.
And presto! Beautiful dark chocolate curls!

You can buy the pink cake stand here which I think adds a pretty, elegant touch to the presentation. It’s a generous size stand which makes it ideal for holding a dozen muffins too! (the link goes to Amazon where I am an Affiliate)

- Pour chocolate over bottom of frozen pan, creating a thin layer. Allow to set until matt and cooled (pop back in freezer if need to help set up) Take a metal bench scrape and scrap chocolate until shards or curls form.
Be sure to allow the cake to set up in the refrigerator for a minimum of 4 hours but overnight is even better. This will help create a nice clean slice.
You could also use milk chocolate but then omit the sugar in the filling recipe since the milk chocolate will be sweet enough
