Ingredients

To achieve this incredible Chocolate Strawberry Mousse Cake, you will need the following ingredients:

12 tablespoons unsalted butter plus 2 tablespoons melted for the pans: This luxurious butter gives the cake a rich and buttery flavor, while the extra melted butter ensures easy removal from the pans.
6 ounces semisweet chocolate, chopped: This velvety chocolate forms the base of your mousse, offering a deep, dreamy richness.
6 egg yolks: The eggs add creaminess and a touch of moisture, contributing to the cake’s soft texture.
1/2 cup plus 1 tablespoon sugar: Sweetening this dish brings balance to the deep flavors, making each bite delightful.
3 egg whites: When whipped, these egg whites instill the mousse with a light and airy consistency.
2 pints strawberries, stems removed: The juicy strawberries add freshness, creating a perfect contrast with the chocolate.
16 ounces semisweet chocolate, chopped: This additional chocolate is crucial for the mousse layer, enhancing the indulgence.
4 ounces white chocolate, chopped: Not just for decoration, white chocolate contributes a touch of contrast to our cake.
6 egg whites (see Notes): Again used to provide that fluffy texture, working wonders in the mousse.
2 tablespoons granulated sugar: This sugar is added with the egg whites to stabilize those peaks.
1 cup heavy cream: Providing richness, whipped cream layers deliver a luscious finish to your dessert.
3/4 cup heavy cream: This additional cream is essential for whipping, ensuring your mousse is heavenly.
1 1/2 tablespoons unsalted butter: It creates a silky texture in your ganache, enhancing the blend of chocolate flavors.
1 1/2 tablespoons granulated sugar: Added to the ganache mix, it helps to sweeten the overall chocolate taste.
9 ounces semisweet chocolate, chopped: This final touch of chocolate creates a smooth and shiny ganache that transforms the cake into a visual masterpiece.

Step-by-Step Directions

Prepare the pans: Lightly coat the insides of two 9 by 1-1/2 inch round cake pans with melted butter. Line the bottom with parchment paper and coat it again with more butter.
Preheat your oven: Set it to 325 degrees, ensuring the perfect bake for your cakes.
Melt the chocolate and butter: In a microwave-safe bowl, combine 6 ounces of semisweet chocolate and 12 tablespoons of butter. Heat for 1 minute, stir, and continue until the mixture is melted and smooth. Allow it to cool.
Mix egg yolks and sugar: In a mixer fitted with a paddle attachment, beat the egg yolks and sugar on high for about 6 minutes until slightly thick.
Whip the egg whites: In another bowl, whip 3 egg whites until stiff peaks form, taking around 3-4 minutes.
Combine mixtures: Gently fold the cooled chocolate mixture into the egg yolk mixture. Then carefully fold in a quarter of the whipped egg whites before incorporating the rest.
Bake the cakes: Divide the batter between the prepared pans and bake for 25-30 minutes. Cool in the pans for 15 minutes, then refrigerate for 30 minutes.
Prepare strawberries: Reserve 12 attractive strawberries for the top of your cake and puree 4 ounces using a blender to create 1/2 cup of strawberry puree. Refrigerate this for later use.
Melt the additional chocolate: In a microwave-safe bowl, combine 16 ounces semisweet chocolate, white chocolate, and the strawberry puree. Heat and stir until smooth, then let cool.
Whip remaining egg whites: In a mixer, whisk the 6 egg whites until soft peaks form, gradually adding 2 tablespoons of sugar.
Whip the heavy cream: Until stiff, then blend a quarter of the egg whites into the chocolate mixture, followed by the whipped cream and remaining egg whites.
Assemble: Place one cake layer in a springform pan, arrange strawberries upright on top, and cover with 3/4 of the mousse. Tap the pan to remove air bubbles and cover with additional mousse if needed. Press the second cake layer on top and refrigerate for 2 hours.
Make the ganache: Heat cream, butter, and sugar in a saucepan. Pour the boiling mixture over the chocolate and let it sit before stirring until smooth and cooling.
Decorate the cake: Set aside some ganache for piping. Carefully remove the sides of the springform and pour the remaining ganache on top, smoothing it out. Refrigerate for at least 1 hour.
Final decoration: Pipe stars along the top and insert strawberries into each star. Chill the cake for an additional 30 minutes before serving.

Note: The Chocolate Strawberry Mousse Cake should be enjoyed within 24 hours for the best taste and aesthetic appeal, as the strawberries may weep into the mousse after that period.

Tips & Tricks

Choice of Chocolate: Using high-quality semisweet chocolate will noticeably enhance the flavor of your cake. Consider brands that use premium cocoa beans.

Temperature Control: Ensure all your ingredients are at room temperature before mixing for a smoother batter.
Whipping Technique: Be gentle while folding the mousse ingredients; this maintains that light, airy texture that is so delicious.
