Chocolate Mousse Tiramisu (Print Version)
Layers of coffee-soaked ladyfingers, chocolate mousse, and mascarpone cream in one showstopping dessert.
# What You'll Need:
→ Chocolate Mousse
01 - 7 oz dark chocolate (70% cocoa), finely chopped
02 - 3 tbsp unsalted butter
03 - 4 large eggs, separated
04 - 1.4 oz granulated sugar
05 - 1 pinch salt
→ Mascarpone Layer
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
# How to Make It:
01 - Place the chopped dark chocolate and unsalted butter in a heatproof bowl set over a pot of barely simmering water. Stir gently until completely melted and smooth. Remove from heat and let cool for about 10 minutes until lukewarm.
02 - In a medium bowl, whisk the egg yolks with half of the granulated sugar until the mixture turns pale yellow and falls in thick ribbons from the whisk, about 3 to 4 minutes.
03 - In a separate clean bowl, beat the egg whites with a pinch of salt using an electric mixer until soft peaks begin to form. Gradually stream in the remaining sugar while continuing to beat until stiff, glossy peaks hold their shape.
04 - Pour the egg yolk mixture into the cooled chocolate and fold gently until uniform. Add the whipped egg whites in three additions, folding carefully with a spatula to preserve as much air as possible. Refrigerate the mousse for at least 30 minutes to firm up.
05 - In a chilled bowl, combine the mascarpone cheese, cold heavy cream, and powdered sugar. Beat with an electric mixer on medium speed until thick, smooth, and spreadable. Set aside.
06 - Pour the cooled strong coffee into a shallow dish and stir in the coffee liqueur if using. Have the ladyfingers ready beside it for quick dipping.
07 - Briefly dip each ladyfinger into the coffee mixture, about 1 to 2 seconds per side, and arrange them in a single layer covering the bottom of an 8x8 inch rectangular dish. Spread half of the mascarpone cream evenly over the ladyfingers, then spoon half of the chocolate mousse on top and smooth it out.
08 - Repeat with a second layer of coffee-dipped ladyfingers, the remaining mascarpone cream, and the rest of the chocolate mousse. Smooth the top, cover tightly with plastic wrap, and refrigerate for at least 4 hours or overnight for the best texture.
09 - Just before serving, use a fine-mesh sieve to generously dust the entire surface with cocoa powder. Cut into squares and serve chilled.
# Expert Advice:
01 -
- Two legendary desserts fused into one means you never have to choose between chocolate mousse and tiramisu again, which honestly feels like a life hack.
- The contrast of pillowy mousse against coffee soaked ladyfingers creates a texture that makes people close their eyes when they take the first bite.
02 -
- Overdipping the ladyfingers is the number one way this dessert goes wrong, so count to two and pull them out fast, trusting that they will continue soaking up moisture from the layers above.
- Folding the egg whites too aggressively will deflate your mousse into something dense and sad, so use a spatula and a patient folding motion even if it feels like it takes forever.
03 -
- Separate your eggs while they are cold because the yolks hold their shape better, then let the whites sit at room temperature for twenty minutes before whipping because they reach full volume faster when not chilled.
- The overnight rest is not optional in my kitchen because the texture transformation from good to extraordinary happens somewhere around hour eight when the flavors fully marry.
