Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
For the base layer:
200 g ladyfinger biscuits
240 ml strong brewed coffee, cooled
2 tablespoons sugar
For the chocolate mousse:
300 g dark chocolate, finely chopped
400 ml heavy cream, cold
3 tablespoons powdered sugar
1 teaspoon vanilla extract
For the mascarpone layer:
250 g mascarpone cheese
100 ml heavy cream
2 tablespoons powdered sugar
For topping:
2 tablespoons unsweetened cocoa powder
Directions
Start by preparing the coffee mixture. Brew strong coffee and let it cool completely, then stir in the sugar until dissolved. Quickly dip each ladyfinger biscuit into the coffee mixture, ensuring they absorb flavor without becoming soggy. Arrange them in a single layer at the bottom of a springform pan.
Next, prepare the chocolate mousse. Melt the dark chocolate gently using a double boiler or microwave in short intervals, stirring until smooth. Allow it to cool slightly. In a separate bowl, whip the cold heavy cream with powdered sugar and vanilla extract until soft peaks form. Gradually fold the melted chocolate into the whipped cream, mixing gently to maintain a light and airy texture.
Spread half of the chocolate mousse evenly over the biscuit layer. Add another layer of coffee-soaked ladyfingers on top of the mousse.
For the mascarpone layer, whisk together mascarpone cheese, heavy cream, and powdered sugar until smooth and slightly thickened. Spread this mixture evenly over the second biscuit layer.
Top with the remaining chocolate mousse, smoothing the surface with a spatula. Cover the cake and refrigerate for at least 6 hours, preferably overnight, to allow the layers to set properly.
Before serving, dust the top generously with unsweetened cocoa powder. Carefully remove the cake from the springform pan, slice, and serve chilled.
Servings and timing
This recipe serves 8 to 10 people, depending on portion size. Preparation takes about 30 minutes, with no baking required. Chilling time is essential and should be at least 6 hours, though overnight chilling yields the best texture and flavor.
Variations
You can customize this cake in several ways to suit your taste. Substitute dark chocolate with milk chocolate for a sweeter version. Add a layer of chocolate ganache on top for extra richness. For a more intense coffee flavor, brush additional coffee onto each biscuit layer. You can also incorporate finely chopped nuts between layers for added texture. If you prefer a lighter version, use whipped cream cheese instead of mascarpone.
Storage/Reheating
Store the cake in the refrigerator, covered, for up to 3 days. Keep it in an airtight container to preserve freshness and prevent it from absorbing other odors. This dessert is best enjoyed cold, so reheating is not necessary. If the cocoa dust fades over time, simply add a fresh layer before serving.
