Ingredients You’ll Need
The beauty of this No-Bake Chocolate Mousse Cake lies in its simplicity. Each ingredient has a purpose: building texture, deepening chocolatey flavor, or adding creamy smoothness. When combined, they transform everyday staples into an extraordinary final dessert.
- Chocolate cookie crumbs: These create the irresistible crunchy base—Oreo crumbs are a classic pick, but any chocolate cookie works.
- Granulated sugar: Just a touch sweetens and helps bind the crust.
- Melted unsalted butter: This brings the crust together and infuses richness.
- Cream cheese (softened): Adds a dreamy silkiness and balances the chocolate with a subtle tang.
- Powdered sugar: Dissolves smoothly into the mousse, keeping it sweet without grittiness.
- Unsweetened cocoa powder: Delivers deep, robust chocolate flavor without making the dessert overly sweet.
- Vanilla extract: Enhances and rounds out all those lovely chocolate notes.
- Cold heavy cream: Whipped into soft clouds, it lightens the mousse and makes it impossibly fluffy.
- For garnish—whipped cream, chocolate shavings, cocoa powder: Finish your masterpiece with swirls, flakes, or a pretty dusting. Totally optional, but totally delicious.
How to Make No-Bake Chocolate Mousse Cake
Step 1: Prepare the Crust
Let’s get started with the foundation of the No-Bake Chocolate Mousse Cake: the crust. Line the bottom of an 8-inch springform pan with parchment to make serving easier later. In a medium bowl, stir together your cookie crumbs, granulated sugar, and melted butter until you have a mixture that looks like damp sand. Scoop it into your prepared pan and press it down evenly—you want a firm base, so really give it a good press. Pop it in the fridge to set for at least 30 minutes while you whip up the mousse layer.
Step 2: Make the Chocolate Mousse
In a large mixing bowl, beat the softened cream cheese until it’s creamy and smooth. Add the powdered sugar, cocoa powder, and vanilla extract, whipping everything together until fully combined and luxuriously thick. Set that aside and, in a separate clean bowl, beat your cold heavy cream until stiff peaks form. Now comes the secret to feather-light mousse: gently fold a third of the whipped cream into the cream cheese mixture to lighten it up, then carefully fold in the rest. Take your time and don’t overmix—airy mousse is the goal!
Step 3: Assemble and Chill
Once your filling is ready and your crust is firm, pile the mousse onto the crust and smooth the top with a spatula. Cover the pan with plastic wrap and let everything chill in the fridge for at least 4 to 6 hours—overnight is even better. This patience pays off, so resist the urge to dig in right away; the cake needs time to firm up and set for perfect slices.
Step 4: Garnish and Serve
When your cake is fully chilled, run a knife around the edges for the smoothest release, then gently remove the sides of the springform pan. Slide the cake onto a serving plate. Add a mountain of whipped cream, a shower of chocolate shavings, and a fluttering of cocoa powder if you’re feeling fancy. Slice it up—each serving is rich, chilled, and completely delightful.

Garnishes
Dress your No-Bake Chocolate Mousse Cake with generous swirls of whipped cream for extra creaminess. Add glossy chocolate curls or rustic chocolate shavings for a bakery-style look, and a few edible flowers or fresh berries for a pop of color. A final whisper of cocoa powder always adds a touch of drama and depth.
Side Dishes
Since this cake is so indulgent, serve it with something fresh for balance. A side of tart raspberries, strawberries, or even a handful of mixed berries works beautifully. For coffee lovers, a small espresso or strong cup of coffee provides the perfect contrast to the cake’s richness.

Make Ahead and Storage
Storing Leftovers
If you find yourself with leftover No-Bake Chocolate Mousse Cake, lucky you! Simply cover the pan tightly or store individual slices in airtight containers in the refrigerator. The texture and flavor stay heavenly for up to 4 days—if it lasts that long.
Freezing
For longer storage, this dessert freezes beautifully. Wrap it well or pack slices in freezer-safe containers. When ready to enjoy, thaw the cake overnight in the fridge for a luscious, make-ahead treat that tastes just as amazing as the day you made it.
Reheating
No reheating required for this chilled delight! In fact, serving No-Bake Chocolate Mousse Cake right from the fridge is what gives it that signature creamy yet sliceable texture. Just take it out a few minutes before serving for the best flavor.
FAQs
Can I use milk chocolate or dark chocolate instead of cocoa powder?
This recipe’s unsweetened cocoa powder is what brings deep, pure chocolate flavor without added sweetness. Using melted chocolate can work, but you’ll need to adjust the sugar—experiment with your favorite blends for different moods!
What if I don’t have a springform pan?
While a springform pan makes unmolding the cake easy as pie (pun intended), you can also use a regular cake pan lined with an overhanging parchment sling for easy lifting. Just be gentle when releasing the cake.
Can I make this No-Bake Chocolate Mousse Cake ahead for a party?
Absolutely! This cake thrives with some extra chill time in the fridge, so making it the day before your event gives you one less thing to worry about—and ensures perfect texture for serving.
Is there a gluten-free option?
Yes! Simply swap in gluten-free chocolate cookies for the crust and you’ll have a completely gluten-free No-Bake Chocolate Mousse Cake that everyone can enjoy, without compromising on flavor or texture.
How do I get really clean slices?
For picture-perfect slices, use a long, sharp knife dipped in warm water and wiped clean between each cut. This helps glide cleanly through the creamy mousse and ensures every piece looks as good as it tastes.
