Ingredients:
- 1.5 cups strong brewed espresso or coffee, cooled
- 2 tbsp dark rum or Marsala wine
- 1 tbsp granulated sugar
- 4 large egg yolks, room temperature
- 0.5 cup granulated sugar
- 16 oz mascarpone cheese, room temperature
- 3 large egg whites, room temperature
- 1 tsp pure vanilla extract
- 35 Savoiardi ladyfingers
- 3 tbsp unsweetened cocoa powder
Instructions:
- Combine the cooled espresso, rum, and 1 tbsp sugar in a shallow bowl. Stir until the sugar is completely dissolved and set aside.
- In a large bowl, beat the egg yolks and 0.5 cup sugar on high for 3-5 minutes until the mixture is pale yellow and thick (the ribbon stage).
- Add the room-temperature mascarpone and vanilla extract to the egg mixture. Beat on low speed just until combined to avoid over-mixing.
- In a separate clean bowl, whip the egg whites until stiff peaks form.
- Gently fold the whipped egg whites into the mascarpone mixture using a spatula, cutting through the center and lifting from the bottom until no white streaks remain.
- Quickly dip each ladyfinger into the coffee mixture for one second per side, ensuring they do not soak through.
- Line the bottom of a 9x9 inch baking dish with the dipped ladyfingers, spread half of the mascarpone cream on top, repeat the layers, and finish with a dusting of unsweetened cocoa powder.
- Refrigerate for 6 to 24 hours to set before serving.
