Chocolate Mousse Tiramisu (Printable)
Coffee-soaked ladyfingers layered with mascarpone and airy chocolate mousse for a decadent Italian-French treat.
# What You'll Need:
→ Chocolate Mousse
01 - 7 oz dark chocolate (70% cocoa), chopped
02 - 3 tbsp unsalted butter
03 - 4 large eggs, separated
04 - 1.4 oz granulated sugar
05 - 1 pinch salt
→ Mascarpone Mixture
06 - 8.8 oz mascarpone cheese
07 - 3.4 fl oz heavy cream, cold
08 - 2 tbsp powdered sugar
→ Assembly
09 - 7 oz ladyfingers (savoiardi)
10 - 8.5 fl oz strong brewed coffee, cooled
11 - 2 tbsp coffee liqueur (optional)
12 - Cocoa powder, for dusting
# Steps:
01 - Place the chopped dark chocolate and unsalted butter in a heatproof bowl set over a pot of simmering water. Stir gently until completely melted and smooth. Remove from heat and let cool for about 5 minutes.
02 - In a separate bowl, whisk the egg yolks with half of the granulated sugar until the mixture turns pale yellow and reaches a creamy, ribbon-like consistency.
03 - In a clean, dry bowl, whip the egg whites with a pinch of salt until soft peaks begin to form. Gradually sprinkle in the remaining sugar while continuing to beat until stiff, glossy peaks hold their shape.
04 - Fold the whisked egg yolk mixture into the slightly cooled chocolate until evenly incorporated. Then gently fold in the whipped egg whites in three additions, using a spatula with light sweeping motions to preserve airiness. Refrigerate the mousse for at least 30 minutes to set.
05 - In a mixing bowl, combine the cold mascarpone cheese, heavy cream, and powdered sugar. Beat with an electric mixer until the mixture is smooth, thick, and spreadable. Set aside.
06 - Pour the cooled strong coffee into a shallow dish and stir in the coffee liqueur if using. Mix well to combine.
07 - Quickly dip each ladyfinger into the coffee mixture—just a brief dunk on each side to avoid sogginess. Arrange the soaked ladyfingers in a single layer covering the bottom of an 8x8 inch rectangular serving dish.
08 - Spread half of the mascarpone cream evenly over the ladyfinger base. Spoon half of the chilled chocolate mousse on top and smooth it into an even layer using a spatula.
09 - Repeat the layering: dip remaining ladyfingers in coffee and arrange over the mousse. Spread the rest of the mascarpone cream on top, then finish with the remaining chocolate mousse, smoothing the surface evenly.
10 - Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours, or ideally overnight for the best texture and flavor development. Just before serving, sift a generous layer of cocoa powder over the top.
# Expert Tips:
01 -
- The contrast between pillowy mousse and coffee soaked ladyfingers will ruin you for ordinary desserts.
- It looks like it took all day but the hands on work is under forty minutes.
- That first spoonful crackling through cocoa into velvet mousse into damp espresso sweetness is pure theatre.
02 -
- If the chocolate is even slightly warm when you add the yolks it will seize into a grainous mess and you will have to start over.
- Over dipping the ladyfingers is the number one reason this dessert turns soggy instead of luscious.
03 -
- Fold the egg whites with a large flexible spatula using a slow cut and fold motion rather than stirring in circles.
- Grate a little extra chocolate between the layers for a surprise crunch that takes this from great to unforgettable.
