Ingredients:
- 1.5 cups strong espresso, room temperature
- 2 tbsp granulated sugar
- 3 tbsp dark rum
- 1 lb mascarpone cheese
- 2 cups heavy whipping cream, chilled (min 36% fat)
- 0.5 cup powdered sugar, sifted
- 2 tsp vanilla bean paste
- 7 oz ladyfingers (Savoiardi)
- 0.25 cup unsweetened cocoa powder
- 1 oz dark chocolate, for grating
Instructions:
- In a shallow bowl, combine 1.5 cups room temperature espresso, 2 tbsp granulated sugar, and 3 tbsp dark rum.
- In a large bowl, gently fold 1 lb mascarpone with a spatula just until it loses its block shape.
- In a chilled mixing bowl, beat 2 cups heavy whipping cream, 0.5 cup sifted powdered sugar, and 2 tsp vanilla bean paste until stiff peaks form.
- Carefully fold the whipped cream into the mascarpone in three batches until a smooth, velvety mousse forms.
- Quickly dip each of the 7 oz ladyfingers into the espresso mixture for 1 second per side and arrange in a single layer in an 8x8 inch dish.
- Spread half of the mascarpone mixture over the ladyfinger layer. Use a fine-mesh sieve to dust a light layer of 0.25 cup cocoa powder over the cream.
- Repeat with a second layer of dipped ladyfingers and the remaining cream mixture. Smooth the top with an offset spatula.
- Cover and refrigerate for a minimum of 6 hours. Before serving, apply a final dusting of cocoa powder and freshly grated 1 oz dark chocolate.
