Ingredients:
For the Chocolate Crumb Crust:
- 1 ½ cups (150g) chocolate cookie crumbs (e.g., Oreo crumbs without the cream, or digestive biscuits mixed with cocoa powder)
- ½ cup (115g) unsalted butter, melted
For the Rich Chocolate Mousse:
- 12 ounces (340g) good quality dark chocolate (60-70% cacao), finely chopped
- 2 tablespoons (30ml) strong hot coffee or espresso (optional, enhances chocolate flavor)
- 4 large egg yolks
- ¼ cup (50g) granulated sugar
- ¼ cup (60ml) whole milk
- 2 cups (480ml) heavy cream, very cold, divided
For the Chocolate Frosting Swirls (or simple ganache topping):
- ½ cup (85g) good quality semi-sweet or dark chocolate chips (or finely chopped chocolate)
- ¼ cup (60ml) heavy cream
- 1 tablespoon unsalted butter, softened (optional, for shine)
- 1 tablespoon powdered sugar (confectioners’ sugar), sifted (optional, for piped frosting)
- 1 teaspoon vanilla extract (optional)
For Garnish:
- Chocolate shavings or chocolate curls (optional)
- Cocoa powder for dusting (optional)
Equipment:
- 9-inch (23 cm) springform pan
- Parchment paper
- Small saucepan
- Heatproof bowls (double boiler setup recommended for melting chocolate)
- Whisk
- Rubber spatula
- Electric mixer (stand mixer or hand mixer)
- Plastic wrap
- Piping bag with a star or round tip (for frosting swirls)
- Cake serving plate
Instructions:
Part 1: Prepare the Chocolate Crumb Crust
- Prepare the Springform Pan: Lightly grease the bottom of a 9-inch springform pan. Line the bottom with a circle of parchment paper. This will help with easy removal of the cake.
- Make Crumb Mixture: In a medium bowl, combine the chocolate cookie crumbs and melted butter. Stir until the crumbs are evenly moistened and resemble wet sand.
- Press the Crust: Press the crumb mixture firmly and evenly into the bottom of the prepared springform pan. Use the back of a spoon or a flat-bottomed glass to compact it well.
- Chill Crust: Place the pan in the refrigerator for at least 15-20 minutes while you prepare the mousse, or freeze for 10 minutes, to allow the crust to set.
Part 2: Prepare the Rich Chocolate Mousse
- Melt Chocolate: Place the finely chopped dark chocolate in a heatproof bowl. If using, pour the hot coffee or espresso over the chocolate. Let it sit for 5 minutes to melt, then stir until completely smooth. If the chocolate isn’t fully melted, you can place the bowl over a saucepan of simmering water (creating a double boiler) and stir until smooth, being careful not to let the bottom of the bowl touch the water. Set aside to cool slightly.
- Prepare Custard Base (Pâte à Bombe): In a separate heatproof bowl, whisk together the egg yolks, granulated sugar, and whole milk.
- Cook Custard: Place this bowl over a saucepan of simmering water (double boiler). Whisk constantly until the mixture thickens slightly and reaches a temperature of 160°F (71°C). It should coat the back of a spoon. This step cooks the egg yolks, making the mousse safe to eat and giving it a rich texture. Remove from heat.
- Combine Chocolate and Custard: Gradually pour the warm egg yolk mixture into the slightly cooled melted chocolate, whisking continuously until the mixture is smooth and well combined. This forms the chocolate base for your mousse.
- Whip First Half of Cream: In a large, very cold mixing bowl, pour 1 cup (240ml) of the cold heavy cream. Using an electric mixer, whip on medium-high speed until soft peaks form. Be careful not to overbeat.
- Fold Cream into Chocolate: Gently fold the whipped cream into the chocolate mixture in two additions, using a rubber spatula. Fold until no streaks of white cream remain, being careful not to deflate the air.
- Pour Mousse into Crust: Pour the chocolate mousse mixture evenly over the chilled crumb crust in the springform pan.
- Chill Mousse: Cover the springform pan loosely with plastic wrap and refrigerate for at least 4-6 hours, or preferably overnight, until the mousse is completely set and firm.
Part 3: Prepare the Chocolate Frosting Swirls (or simple ganache topping)
This section provides options. Choose one based on your desired look.
Option A: For Piped Frosting Swirls (as seen in image):
- Whip Remaining Cream: In a clean, cold mixing bowl, whip the remaining 1 cup (240ml) of very cold heavy cream until soft peaks form.
- Melt Chocolate (for frosting): Melt the ½ cup of chocolate chips either in a microwave in 20-second intervals, stirring between each, or over a double boiler. Let it cool slightly.
- Make Chocolate Whipped Cream: Gently fold the cooled melted chocolate, sifted powdered sugar (if using), and vanilla extract (if using) into the whipped cream until just combined. Be careful not to overmix, or it may lose its airiness.
- Pipe Swirls: Transfer the chocolate whipped cream to a piping bag fitted with a star or round tip. Pipe decorative swirls around the edge of the set chocolate mousse cake.
Option B: For a Simple Ganache Glaze (alternative to piped swirls):
- Heat Cream: In a small saucepan, heat the ½ cup heavy cream until it just begins to simmer.
- Melt Chocolate and Butter: Pour the hot cream over the ½ cup chocolate chips (and softened butter, if using) in a heatproof bowl. Let it sit for 5 minutes, then stir until smooth and glossy.
- Cool Slightly: Let the ganache cool for about 15-20 minutes, stirring occasionally, until it’s slightly thickened but still pourable.
- Pour over Cake: Gently pour the cooled ganache over the top of the set mousse cake and spread it evenly, allowing it to drip slightly over the edges if desired.
Part 4: Final Assembly and Garnish
- Release from Pan: Once the chocolate mousse cake is completely set (after chilling), carefully run a thin knife around the edge of the springform pan before releasing the sides.
- Transfer to Serving Plate: Carefully transfer the cake to your desired serving plate.
- Garnish: If not already decorated, garnish the cake with chocolate shavings or curls for an elegant finish.
Part 5: Serve
- Serve Chilled: This cake is best served chilled. Allow it to sit at room temperature for 10-15 minutes before slicing for easier cutting and optimal texture.
- Slice and Enjoy: Slice the Irresistible Chocolate Mousse Cake with a sharp, warm knife and serve immediately. Share it with a smile, just like in the image!
Tips for Success:
- Quality Chocolate is Crucial: Because chocolate is the star ingredient, use a high-quality chocolate that you enjoy eating on its own. This will significantly impact the flavor of your mousse.
- Don’t Rush Chilling: The mousse needs ample time to set properly. Rushing this step will result in a runny cake. Chilling overnight is ideal.
- Whipping Cream Properly: Ensure your heavy cream is very cold, and for best results, chill your mixing bowl and whisk attachment as well. This helps the cream whip up faster and hold its volume.
- Folding Gently: When folding the whipped cream into the chocolate mixture, use a gentle hand to avoid deflating the air, which is essential for a light and airy mousse.
- Tempering Egg Yolks: The “Pâte à Bombe” step (cooking the egg yolks with sugar and milk) ensures food safety and adds richness and stability to the mousse. Whisk constantly over the double boiler to prevent scrambling.
- Clean Slices: For clean slices, use a sharp knife. If the ganache is firm, dip the knife in hot water and wipe it dry between each slice.
- Storage: Store leftover chocolate mousse cake in an airtight container in the refrigerator for up to 3-4 days.
- Make Ahead: This cake is an excellent make-ahead dessert since it requires significant chilling time. You can prepare it a day or two in advance.
- Customization:
- Flavor Boost: Add a touch of orange zest, peppermint extract, or a splash of rum/brandy to the mousse for an extra flavor dimension.
- Different Crusts: Instead of chocolate cookies, you could use graham cracker crumbs or even crushed shortbread for the crust.
- Fruit Garnish: Fresh raspberries or strawberries would provide a beautiful color contrast and a tart counterpoint to the rich chocolate.
