Ingredients You’ll Need
To create the perfect Chocolate Mousse Cake, you will need a handful of simple yet carefully chosen ingredients. Each one plays a vital role in building the layers, texture, and deep chocolate flavor that defines this cake.
- All-purpose flour: The foundation of the cake layer providing structure without heaviness.
 - Natural cocoa powder: Adds that deep, earthy chocolate flavor and a beautiful dark color.
 - Baking powder and baking soda: Essential for making the cake layer rise just right.
 - Salt: Enhances the chocolate flavor and balance sweetness.
 - Egg: Acts as a binder and adds richness to the cake.
 - Granulated sugar and brown sugar: For sweetness and moisture, the brown sugar adds a slight caramel note.
 - Light-tasting oil: Keeps the cake tender and moist.
 - Milk: Adds moisture and helps create a smooth batter.
 - Whipping cream or heavy cream: Used twice—once for luscious chocolate mousse and again for a silky ganache topping.
 - Dark or semi-sweet chocolate: The star ingredient that melts into both the mousse and ganache to deliver that popular bittersweet chocolate punch.
 - Fresh strawberries: Provide a refreshing contrast and a pop of color that makes the cake truly irresistible.
 
How to Make Chocolate Mousse Cake
Step 1: Bake the Chocolate Cake Layer
First, preheat your oven and prepare your springform pan—no need to fuss with parchment paper unless you prefer it. Mix your dry flour, cocoa powder, baking powder, baking soda, and salt in one bowl, and whisk your egg with sugars and oil in another. Alternate gently blending the dry ingredients with milk into the wet mixture to create a luscious, thick but smooth batter. Pour into the pan and bake until a toothpick slips out with just a few moist crumbs. Once cool, level your cake layer to ensure smooth mousse layering later.
Step 2: Prepare the Decadent Chocolate Mousse
Warm half of the whipping cream just to a simmer, then pour it over finely chopped dark chocolate and let it sit peacefully to melt. Stir gently until the mix turns glossy and smooth. Meanwhile, whip the remaining cream until you achieve soft peaks—this step is crucial because overwhipping will ruin the mousse’s creamy texture. Fold a third of your whipped cream into the chocolate blend before carefully folding it all together, maintaining that airy lightness.
Step 3: Assemble the Cake with Strawberries and Mousse
Place your cake layer back in the pan and decorate the sides with halved fresh strawberries, cut side against the pan to create a stunning border inside the cake ring. Pour the silky mousse over the cake and between the strawberries, smoothing the top evenly. Cover your masterpiece and let it chill for at least 4 hours or overnight to set beautifully.
Step 4: Create the Glossy Chocolate Ganache Topping
For the grand finishing touch, heat cream again and pour it over chopped chocolate, allowing it to melt and become shiny ganache. After mixing well and letting it thicken slightly, pour it over the chilled mousse layer and spread evenly. Return the cake to the fridge for another 30 minutes so the ganache firms up while you prepare to impress your guests.
Step 5: Decorate and Slice
Once your ganache has set, adorn the top with extra strawberries for color and freshness. For clean slices, rinse your knife in hot water and dry it before cutting—this keeps the ganache smooth and prevents smudging.
How to Serve Chocolate Mousse Cake

Garnishes
Fresh strawberries are the perfect natural garnish, their bright red hues and tartness balancing the richness of the cake. You can also dust a little cocoa powder or shave some dark chocolate on top for an elegant, finishing touch.
Side Dishes
Serve slices of Chocolate Mousse Cake with a dollop of lightly whipped cream or a scoop of vanilla ice cream to add dimension. For a refreshing counterpoint, a simple fruit salad featuring berries and mint complements the rich chocolate flavors wonderfully.
Creative Ways to Present
For a show-stopping presentation, serve individual mousse cake portions in clear glass jars, layering cake, mousse, and ganache separately. Alternatively, try garnishing the platter with edible gold leaf, chocolate curls, or even a drizzle of raspberry coulis for a gourmet flair.
Make Ahead and Storage
Storing Leftovers
The Chocolate Mousse Cake keeps beautifully in the refrigerator for up to 3 days. Make sure to cover it tightly with plastic wrap or store it inside an airtight container to maintain moisture and prevent it from absorbing other flavors.
Freezing
If you want to freeze your cake, wrap it securely in plastic wrap and then aluminum foil to avoid freezer burn. It’s best consumed within 1 month for optimal taste and texture. Thaw overnight in the fridge before serving to keep the mousse and ganache layers perfect.
Reheating
This cake is best enjoyed chilled, so no reheating is needed. Simply bring it to cool room temperature for about 20 minutes before serving if you prefer a softer texture, but avoid heat as it can cause the mousse to lose its delicate structure.
FAQs
Can I use milk chocolate instead of dark chocolate?
Absolutely! Using milk chocolate will result in a sweeter, milder cake, so consider adjusting the sugar levels slightly if you prefer a less sweet dessert.
Do I need an electric mixer to whip the cream?
While an electric mixer makes the job easier and faster, you can certainly whisk the cream by hand—just be patient and watch carefully to achieve soft peaks without overwhipping.
Can I substitute the strawberries with other fruits?
Yes! Raspberries, cherries, or even thinly sliced kiwi can offer different flavors and colors that pair nicely with chocolate. Choose fruits that won’t release too much juice to keep your cake layers intact.
Is it possible to make this cake gluten-free?
Definitely. Substitute all-purpose flour with a gluten-free flour blend designed for baking. The texture might be slightly different but still delicious.
How long does it take to prepare the Chocolate Mousse Cake?
Including baking, chilling, and assembling time, this cake takes about 6 hours and 15 minutes to make, with most of that time spent chilling to let the mousse and ganache properly set.
