Ingredients You’ll Need
Getting the ingredients right is key to nailing the perfect texture and flavor of the Chocolate Strawberry Silk Cake. Each component plays a specific role, from richness in the mousse to freshness in the strawberry compote, and even the shine of the glaze.
- High-quality dark chocolate: The foundation of the mousse that gives it a deep, intense chocolate flavor.
- Fresh strawberries: Used both in the compote and as garnish, they provide natural sweetness and a lovely color pop.
- Eggs: Essential for creating that smooth, airy mousse texture.
- Sugar: Balances the tartness of strawberries and enhances the chocolate’s sweetness.
- Heavy cream: Whipped to add lightness and silkiness to the mousse.
- Butter: Adds richness and helps with the cake base’s tender crumb.
- Flour (all-purpose): Just enough for the thin chocolate sponge base that supports the mousse without overwhelming it.
- Gelatin: Provides structure to the mousse so it sets perfectly while remaining soft.
- Vanilla extract: Enhances the overall flavor complexity.
- Cocoa powder: For a subtle chocolate depth in the sponge base.
- Semi-gloss glaze (optional): Gives the cake that stunning shiny finish.
- Chocolate decorations: Adds elegance and texture for the finishing touch.
How to Make Chocolate Strawberry Silk Cake
Step 1: Prepare the Strawberry Compote
Begin by washing and hulling fresh strawberries, then chop them roughly. Simmer the strawberries gently with a bit of sugar until they release their juices and thicken into a luscious compote. This tart-sweet layer will perfectly complement the richness of the chocolate mousse.
Step 2: Bake the Thin Chocolate Sponge Base
Create a delicate chocolate sponge by combining flour, cocoa powder, eggs, sugar, and melted butter. Pour the batter into a round cake pan and bake just until set so it remains light and spongy. This base anchors the mousse without feeling heavy, giving a subtle chocolate backbone.
Step 3: Make the Chocolate Mousse
Melt the high-quality dark chocolate slowly to preserve its shine and flavor. Whip the heavy cream until soft peaks form, then carefully fold it into the melted chocolate along with whipped egg whites and softened gelatin for that signature airy silkiness. This mousse is the heart of the cake—rich but feather-light.
Step 4: Assemble the Cake
On your chilled chocolate sponge base, spread a generous layer of the cooled strawberry compote. Then, spoon and smooth the chocolate mousse over the compote, creating a thick, even layer. Chill the whole cake for several hours to let the mousse set firm but maintain its silk texture.
Step 5: Glaze and Garnish
For a professional finish, pour a shiny semi-gloss glaze over the chilled mousse layer. The glaze should be smooth and glossy, enhancing the cake’s visual appeal. Arrange fresh strawberries and chocolate decorations artfully on top to create an elegant finish that’s as beautiful as it is delicious.
How to Serve Chocolate Strawberry Silk Cake

Garnishes
Fresh strawberries sliced just before serving brighten the rich chocolate and align with the flavors inside. A few dark chocolate curls or shards add a luxurious crunch and elevate the cake’s presentation to something truly special.
Side Dishes
This cake pairs wonderfully with lightly whipped cream or a scoop of vanilla bean ice cream, which adds coolness and a creamy contrast. For a more grown-up touch, a small glass of port or a fruity dessert wine can bring out the berry notes beautifully.
Creative Ways to Present
Serve individual slices on elegant dessert plates with a drizzle of strawberry coulis around the edges. Alternatively, add edible flowers or gold leaf accents for an unforgettable centerpiece at romantic dinners or celebratory events. The Chocolate Strawberry Silk Cake already shines on its own, but these small touches make it even more memorable.
Make Ahead and Storage
Storing Leftovers
Keep any leftover Chocolate Strawberry Silk Cake tightly covered in the refrigerator. It will stay fresh and delicious for up to 3 days, allowing flavors to meld further and the mousse to maintain its perfect silkiness.
Freezing
You can freeze the cake if you want to prepare it well in advance. Wrap it securely in plastic wrap and aluminum foil to avoid freezer burn. Thaw the cake in the refrigerator overnight before serving to preserve the layers and textures perfectly.
Reheating
This cake is best enjoyed chilled, so avoid reheating. If you want your cake to be less firm, simply leave it at room temperature for 15-20 minutes before serving to let the mousse soften slightly without losing its structure.
FAQs
Can I use frozen strawberries for the compote?
Yes, frozen strawberries work fine and often have great flavor. Just thaw them completely and drain any excess liquid before making the compote to get the right consistency.
Is this cake suitable for beginners?
Absolutely! While it might look impressive, the steps are straightforward with some patience, especially when whipping mousse and layering. It’s a perfect project for those ready to explore mousse cakes.
Can I substitute the dark chocolate with milk chocolate?
You can, but the cake will be sweeter and less intense. Dark chocolate provides the perfect balance with the tartness of the strawberries, so aim for at least 60% cacao if possible.
Do I need gelatin for the mousse?
Gelatin helps the mousse hold its shape but you could experiment with alternatives like agar-agar. However, gelatin is traditional and gives that classic silky texture that defines the cake.
How long can I chill the cake before serving?
Chilling for at least 4 hours is essential for the mousse to set properly, but it can also be prepared a day ahead, which even enhances the flavor melding and makes serving easier.
