If you’re looking for a swoon-worthy chocolate dessert, I’ve got you covered with this sublime Frozen Chocolate Mousse Cake.
This Triple Chocolate Mousse Cake starts with a flourless chocolate cake base, which is topped with an incredibly rich and creamy mousse and iced with a glossy ganache. It was perfect for a friend facing back surgery and her chocoholic husband.
Why You Must Make this Mousse Cake Recipe
- Frozen desserts are perfect for gifting as they don’t need to be eaten right away and are terrific for unexpected company or those chocolate cravings! My girlfriend is a chocolate fanatic and I knew having slices of this dreamy frozen chocolate mousse cake in her freezer would brighten up a dreary day of rehab.
- There are three layers of decadence in this frozen mousse cake: a flourless chocolate cake, a layer of dreamy mousse, and a topping of chocolate ganache!
- Each one is fabulous on its own, but together, they create a chocolate extravaganza!
- It can be made weeks ahead of time, so you can fix it when you have time, not the day you’re entertaining or bringing it to an event.
Frequently Asked Questions
What is Mousse Cake?
A mousse cake can be a traditional cake, brownie, or another baked good that has a layer of mousse. The mousse component can use cream or eggs to give it the classic airy or fluffy texture.
A mousse cake can also be a dense mousse that’s sliced into wedges like a cake. It may or may not have a crust.
How to Make a Mousse Cake?
Often mousse is used as a cake filling or topping, making a “mousse cake.”
To make this mousse cake, the flourless chocolate cake is baked, cooled, and frozen. Then the mousse is made. The chocolate mousse is spread over the cake, then returned to the freezer. Finally, the ganache is made, spread over the frozen mousse, and frozen.
Can You Freeze a Mousse Cake?
This mousse cake freezes well for 1-2 months if wrapped well. This recipe is meant to be frozen, but remember to let it soften for a few minutes before serving so it’s not rock hard.
Mousses made with eggs do not freeze as nicely. Their texture may become slightly grainy when defrosted.
Tips for Making This Frozen Chocolate Mousse Cake
There are 3 layers, with the final ganache topping being the easiest. You can make the cake layer one day, then the mousse and ganache on the next if you want to spread out the process. Note there are affiliate links below.
- To get the mousse cake out of the springform pan, use non-stick foil to line it. I used two pieces placed perpendicular to each other so that all the inner surface was covered.
- Even if the foil is pressed tightly against the inside of the pan, you’ll still see wrinkles and folds on the sides of the dessert when it’s unmolded. No one except the baker will notice this!
- Do you know what a springform pan is? It’s used mainly for cheesecakes, but works great for any cakes. It has a removable base and a “collar” for the sides which can be released with a clip. It’s a must for this mousse cake.
- Use this cake spatula for moving cakes and cheesecakes from the pan to the serving plate.
- The eggs must be separarted to make the mousse. PRO-Tip: Remember that eggs separate easiest when cold, but egg whites whip best when at room temperature.
- PRO-Tip: And note that any yolk that contaminates the egg whites (or any grease on the bowl or beaters) will prevent them from whipping into stiff peaks. It’s worth taking your time separating the eggs so none are wasted.
- The cake layer will shrink as it cools, so the mousse layer invariably will be a little bit wider than the cake below.
- To cut, use a long, sturdy bread knife. It worked well as it could straddle the whole cake. Warming the knife helps cut through a frozen dessert if needed.
- Let this dessert to sit out at room temperature after it’s sliced and placed on dessert plates. It slices cleanly when frozen solid, but let it soften for a few minutes to make for easier indulging.
- PRO-Tip: Cold inhibits a dish’s flavor. So for desserts like ice cream, you need to bump up the flavorings a bit.

Gluten-Free Mousse Cake
I brought this cake to my friend, Candes, with a couple of pre-cut slices for her and our other friends to sample at one of our knitting group meetings. Our hostess is gluten-free so rarely gets to enjoy my treats. She was happy to indulge as was the rest of the crew.
I left a slice at home for my own chocolate taste tester—and this was unequivocally a hit across the board. I found this recipe on the blog of my dear blogger friend, Danielle. She and I cook from each other’s blogs each month, and when I spied this chocolate number on Hugs & Cookies XOXO, I knew it would bring sheer bliss to all who indulged.
I got an email from Candy only days after her surgery, requesting the recipe. Her husband told her it was the only chocolate cake she ever needed to make. And she clarified that it was most likely the only dessert she’d ever need to make! If you’re looking for a showstopping treat for the chocoholic in your life, you’ve found it.
On the second Monday of each month, Danielle and I cook up something from each other’s blog. Every treat I pull from her blog is a winner…I never have to worry whether we’ll like it or not. We always do!
