Ingredients:
- 300ml strong espresso, cooled to room temperature
- 30g granulated sugar
- 30ml dark rum
- 500g mascarpone cheese, room temperature
- 4 large egg yolks
- 100g granulated sugar
- 240ml heavy whipping cream, cold
- 5ml vanilla bean paste
- 250g Savoiardi ladyfingers
- 20g unsweetened cocoa powder
Instructions:
- Whisk 30g sugar and dark rum into the cooled espresso in a shallow bowl until fully dissolved. Set aside at room temperature.
- In a large bowl, beat the 4 egg yolks and 100g sugar together for 3-5 minutes until the mixture is pale, thick, and doubled in volume.
- Gently fold the room-temperature mascarpone into the egg yolk mixture until smooth and no lumps remain.
- In a separate chilled bowl, whip the heavy cream and vanilla bean paste until stiff peaks form.
- Fold the whipped cream into the mascarpone mixture in three additions, maintaining as much air as possible until a velvet mousse is formed.
- Quickly dip each ladyfinger into the espresso mixture (1 second per side). Do not oversaturate.
- Arrange a single layer of dipped ladyfingers in the bottom of a 9x9 inch glass dish. Spread half of the mascarpone cream over the top.
- Repeat with a second layer of dipped ladyfingers and the remaining cream. Smooth the top with a spatula.
- Dust the top generously with cocoa powder using a fine-mesh sieve.
- Refrigerate for at least 4 hours to allow the structure to set and the flavors to meld.
