How to Prepare
Begin by preheating your oven to 350 degrees Fahrenheit (175 degrees Celsius). Grease and flour an 8 inch round cake pan.
Melt the dark chocolate and butter together in a heatproof bowl over simmering water, stirring until smooth. Remove from heat and let it cool slightly.
In a separate bowl, whisk the egg yolks with half of the sugar until pale and creamy. Gently fold the melted chocolate mixture into the egg yolks.
In another clean bowl, beat the egg whites with a pinch of salt until soft peaks form. Gradually add the remaining sugar and continue beating until stiff peaks form.
Fold the egg whites carefully into the chocolate mixture in batches, being careful not to deflate the batter.
Sift the flour and cocoa powder over the mixture and gently fold them in until just combined.
Pour the batter into the prepared cake pan and bake for about 25-30 minutes or until a toothpick inserted into the center comes out clean. Let the cake cool completely before assembling the mousse layer.
To make the mousse, whip the heavy cream with vanilla extract until soft peaks form. Spread the whipped cream over the cooled cake. Chill the cake in the refrigerator for at least 2 hours before serving to let the mousse set.
Perfect Pairings and Toppings
This decadent chocolate mousse cake pairs beautifully with fresh berries like raspberries or strawberries, which add a bright, tangy contrast to the rich chocolate. A dollop of whipped cream or a scoop of vanilla ice cream also complements the creamy texture and balances the sweetness.
For toppings, consider garnishing with chocolate curls, shaved dark chocolate, or a dusting of cocoa powder for an elegant finish. A drizzle of caramel or raspberry sauce can add an extra layer of flavor and make the dessert feel even more special. These simple additions elevate the cake while keeping the focus on its luscious chocolate mousse.
