Chocolate Mousse Tiramisu (Printable Version)
Coffee-soaked ladyfingers layered with mascarpone and velvety dark chocolate mousse for an unforgettable dessert.
# What You 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 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
# Directions:
01 - Combine the chopped dark chocolate and unsalted butter in a heatproof bowl set over a pan of simmering water. Stir gently until completely melted and smooth. Remove from heat and allow to cool slightly for about 5 minutes.
02 - In a separate bowl, whisk the egg yolks with half of the granulated sugar (about 0.7 oz) vigorously 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 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 whisked egg yolk mixture into the slightly cooled chocolate and fold gently until uniform. Then, working in three additions, carefully fold the whipped egg whites into the chocolate base using a spatula, preserving as much air as possible. Refrigerate the mousse for at least 30 minutes to firm up.
05 - In a mixing bowl, combine the cold mascarpone cheese, heavy cream, and powdered sugar. Beat with an electric mixer on medium speed 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. Have the ladyfingers ready beside the dish for quick dipping.
07 - Briefly dip each ladyfinger into the coffee mixture—just a quick dunk, about 1 to 2 seconds per side—and arrange them in a single layer covering the bottom of an 8x8 inch rectangular serving dish. Spread half of the mascarpone cream evenly over the soaked ladyfingers, then spoon half of the chilled chocolate mousse on top and smooth into an even layer.
08 - Repeat the process: dip more ladyfingers and lay them over the mousse layer. Spread the remaining mascarpone cream over the ladyfingers, then top with the rest of the chocolate mousse, smoothing the surface evenly.
09 - Cover the dish tightly with plastic wrap and refrigerate for at least 4 hours, preferably overnight, to allow the layers to set and the flavors to meld. Just before serving, sift a generous layer of cocoa powder over the top using a fine-mesh sieve.
# Expert Tips:
01 -
- The mousse layer is lighter than traditional tiramisu cream, so you never hit that heavy wall halfway through a slice.
- It looks like you spent all day on it, but the hands on work is under an hour.
- Coffee and chocolate are already best friends, so stacking them in layers just feels inevitable.
02 -
- Over dipping ladyfingers is the number one way to turn this into soup, so count to two and pull them out fast.
- Folding the egg whites too aggressively will flatten the mousse into something closer to frosting, which still tastes fine but loses that cloud like texture.
03 -
- A single drop of yolk in your egg white bowl will prevent stiff peaks from ever forming, so separate your eggs one at a time into a small dish first.
- The mousse tastes dramatically different depending on the chocolate you choose, so taste your chocolate plain before melting and pick one you genuinely enjoy eating.
