- 1/2 cup brewed espresso
- 3 tablespoons Marsala wine, divided
- 2 eggs, separated
- 2 tablespoons white sugar
- 1 teaspoon white sugar
- 3/4 cup mascarpone cheese
- 1/2 teaspoon vanilla extract
- 1 pinch salt
- 10 ladyfinger cookies, broken in half, or more as needed
- 1 tablespoon cocoa powder
- 1/2 ounce dark chocolate, grated
- Stir espresso and 2 tablespoons Marsala wine together in a shallow bowl.
- Whisk egg yolks, 2 tablespoons plus 1 teaspoon sugar, and 1 tablespoon Marsala wine together in the top of a double boiler over simmering water, until thick, pale yellow, and creamy, 5 to 6 minutes.
- Whisk egg yolk mixture, mascarpone cheese, vanilla extract, and salt together in a bowl until completely smooth.
- Beat egg whites in a glass or metal bowl until stiff peaks form. Lift your beater or whisk straight up: the egg whites will form sharp peaks. Gently stir and fold 1/2 the egg whites into egg yolk mixture; fold in remaining 1/2 egg whites.
- Place 1 heaping spoonful mascarpone mixture into a single-serving cup or glass. Dip 2 ladyfinger cookie halves briefly in espresso mixture and turn 3 to 4 times to coat. Place cookie halves in the bottom of the glass on top of mascarpone.
- Fill the glass halfway with mascarpone mixture. Dip 5 ladyfinger halves in the espresso mixture and place vertically along the inside of the glass, dipping and placing more ladyfinger halves as necessary to fit the glass. Place 2 dipped ladyfinger halves horizontally on top of the mascarpone mixture. Fill glass to the top with mascarpone mixture. Repeat for the second serving glass.
- Wrap both glasses in plastic wrap and refrigerate for at least 8 hours or overnight. Remove plastic wrap and dust tops with cocoa powder and grated chocolate.
