Birthday Tiramisu

My Chief loves tiramisu, so I thought I would try and make something new!   

Ingredients

• 6 egg yolks
• 3/4 cup white sugar
• 2/3 cup milk
• 1 1/4 cups heavy cream
• 1/2 teaspoon vanilla extract
• 1 pound mascarpone cheese
• 1/2 cup strong brewed coffee, room temperature
•  4 tablespoons rum
• 2 (3 ounce) packages ladyfinger cookies
• 1 tablespoon unsweetened cocoa powder

Directions

1. In a medium saucepan, whisk together egg yolks and sugar until well blended. Whisk in milk and cook over medium heat, stirring constantly, until mixture boils. Boil gently for 1 minute, remove from heat and allow to cool slightly. Cover tightly and chill in refrigerator 1 hour.
2. In a medium bowl, beat cream with vanilla until stiff peaks form. Whisk mascarpone into yolk mixture until smooth.
3. In a small bowl, combine coffee and rum. Split ladyfingers in half lengthwise and drizzle with coffee mixture.
4. Arrange half of soaked ladyfingers in bottom of a 7x11 inch dish. Spread half of mascarpone mixture over ladyfingers, then half of whipped cream over that. Repeat layers and sprinkle with cocoa. Cover and refrigerate for 4 to 6 hours, until set or 24 for the best flavor.
