Ingredients You’ll Need

Gathering simple, high-quality ingredients is the first step to creating this divine dessert. Each element plays a vital role, from the cocoa in the cake for deep chocolate flavor to the fresh strawberries that add a burst of color and brightness.

• 115 g all-purpose flour: Provides the structure for a tender yet sturdy cake base.
• 40 g natural cocoa powder: Delivers the rich chocolate flavor that defines the cake.
• ½ teaspoon baking powder: Helps the cake rise to perfection, keeping it light.
• ¼ teaspoon baking soda: Works with the cocoa for a better crumb texture.
• ¼ teaspoon salt: Enhances and balances the sweetness.
• 1 large egg, room temperature: Binds ingredients and adds moisture.
• 50 g granulated sugar: Sweetens while maintaining a fine crumb.
• 50 g brown sugar: Adds a subtle caramel note for depth.
• 110 g light-tasting oil: Keeps the cake moist and tender.
• 200 g milk, room temperature: Provides richness, helping create a smooth batter.
• 400 g whipping cream (divided): Key to creating the light, fluffy mousse and luxurious ganache.
• 200 g dark or semi-sweet chocolate: Forms the luscious chocolate mousse layer.
• 170 g dark chocolate: For the rich, glossy ganache topping.
• 10 fresh strawberries, halved: Adds beautiful color and a fresh, tangy contrast to the chocolate.

How to Make Chocolate Mousse Cake

Step 1: Bake the Chocolate Cake Layer

Start by preheating your oven to 350°F and preparing your 9-inch springform pan. The flour, cocoa powder, baking powder, baking soda, and salt combine to create a perfectly balanced dry mix that forms the base for the cake’s rich chocolate body. Beat your egg with both sugars until well combined and smooth, then blend in the oil. Alternate adding your dry ingredients and milk in parts ensures a batter that’s thick yet fluid, perfect for a moist texture. Pour the batter into the pan and bake for about 30-32 minutes until a toothpick comes out mostly clean. Let the cake cool completely before leveling it if needed to create a flat foundation for your mousse.

Step 2: Prepare the Chocolate Mousse

While the cake cools, melt the dark or semi-sweet chocolate by pouring hot cream over it and letting the heat gently work its magic. Once silky and smooth, cool slightly while whipping the remaining cream to soft peaks—the secret to that astonishingly light and creamy mousse. Folding the whipped cream carefully into the chocolate mixture keeps all that lovely air intact. When your cake layer is ready in the pan, arrange the sliced strawberries around the edges, pressing them lightly into the pan. Spread the chocolate mousse evenly over the cake and strawberries, smoothing the surface, then refrigerate for at least 4 hours or overnight to properly set the mousse.

Step 3: Create and Apply the Chocolate Ganache Topping

The final crowning glory is a glossy ganache, made by melting dark chocolate with heated cream until rich and shiny. Allow it to cool just enough to thicken slightly, then pour it over the chilled mousse layer, smoothing it out to the edges. This shiny, decadent layer adds richness and stunning visual appeal. Let the cake chill for another 30 minutes to set the ganache. Once firm, decorate the top with fresh strawberries for a pop of color and freshness just before slicing.

How to Serve Chocolate Mousse Cake

Garnishes

Extra garnishes elevate your Chocolate Mousse Cake to the next level. Aside from the fresh strawberries already featured in the recipe, consider adding a dusting of cocoa powder, a sprinkle of chopped toasted nuts, or a few edible gold flakes for that wow factor. A dollop of lightly sweetened whipped cream on the side can also heighten the indulgence.

Side Dishes

The beauty of this Chocolate Mousse Cake is that it can shine as a standalone dessert, but if you’re looking to round out your dessert experience, serve it alongside a scoop of vanilla bean ice cream or a tangy raspberry sorbet. These contrasting flavors freshen the palate and add delightful temperature contrasts.

Creative Ways to Present

Presentation makes every bite feel special. Try serving individual slices on chilled white plates to highlight the cake’s rich colors. You can also cut smaller mousse cake squares and stack them on cocktail sticks for a sophisticated dessert buffet. Alternatively, arrange the cake on a beautiful slate board and scatter additional strawberries and mint leaves around the base for a rustic yet elegant look.

Make Ahead and Storage

Storing Leftovers

Chocolate Mousse Cake keeps beautifully in the refrigerator for up to 3 days. Store it in an airtight container or keep it covered with plastic wrap to prevent it from absorbing any fridge odors. The mousse stays wonderfully creamy, and the cake doesn’t dry out, so you can enjoy every bite like it was freshly made.

Freezing

You can freeze this cake for up to one month if you want to prepare ahead or save leftovers. Make sure the cake is tightly wrapped in plastic wrap and then placed in an airtight container or freezer bag. When ready to enjoy, thaw the cake overnight in the refrigerator to keep that sublime texture intact.

Reheating

This cake is best enjoyed chilled, so reheating is not recommended. If preferred, simply allow the cake to sit at room temperature for 10-15 minutes before serving to soften the ganache and mousse slightly for a melt-in-your-mouth experience.

FAQs

Can I use milk chocolate instead of dark chocolate for the mousse?

Absolutely! Milk chocolate will create a sweeter, milder mousse, which is perfect if you prefer a less intense chocolate flavor. Just be mindful that the overall sweetness will increase, so consider adjusting other sweet ingredients accordingly.

Do I need a special pan to make this Chocolate Mousse Cake?

A 9-inch springform pan is ideal because its removable sides make it much easier to release the delicate cake without damaging it. However, if you don’t have one, a regular cake pan lined with parchment paper can work—just be very gentle when unmolding.

Can I substitute heavy cream with a dairy-free alternative?

For dairy-free or vegan versions, coconut cream is a fantastic substitute as it whips well and pairs beautifully with chocolate. It will add a subtle coconut flavor that complements the overall dessert nicely.

How do I prevent the cake from doming when baking?

Using cake strips around the pan can help distribute heat more evenly and prevent doming. Alternatively, you can level the cake after baking using a serrated knife, as described in the recipe steps.

Is it okay to prepare the cake a day in advance?

Yes! Preparing your Chocolate Mousse Cake a day ahead lets the mousse set properly and flavors meld for a more harmonious and satisfying dessert. Just keep it well covered in the refrigerator.
