- 7 egg yolks
- 1/2 cup sugar
- 1/3 cup sweet marsala, plus 2 tablespoons
- 8 ounces mascarpone, softened to room temperature
- 1 cup heavy cream
- 1 cup brewed espresso coffee
- 1 ounce dark chocolate
- 1/4 cup rum
- 1 teaspoon natural vanilla extract
- 48 ladyfingers
- 1/4 cup unsweetened cocoa powder
Cream together egg yolks and sugar in a heatproof bowl set over a pot of simmering water. Add 1/3 cup of the marsala and continue to whisk until mixture is thick and doubled in volume. This is basically a zabaglione. Remove from heat. Stir in the mascarpone until completely blended.
In a small saucepan, combine espresso, chocolate, rum, vanilla, and remaining 2 tablespoons marsala. Heat gently, and stir to dissolve the chocolate. Then, chill the mixture to cool it down, about 15 minutes. Quickly dip each ladyfinger in the chilled coffee mixture and arrange in a single layer on a 9 by 13-inch glass baking pan. Do not soak the cookies or they will become too moist. Spread 1/2 the mascarpone cream evenly with a spatula on top of the dipped ladyfingers. Repeat with a second layer of dipped ladyfingers and remaining mascarpone cream. Sprinkle top with cocoa powder. Refrigerate for 2 hours before serving.
