Tiramisu

Mix together the milk, coffee, rum and sugar. Soak lady fingers in the coffee mixture. Layer 1/2 of the soaked ladyfingers in the bottom of a 9x13 inch pan. Beat together egg yolks and 2 tablespoons sugar. Add the mascarpone cheese and 1 tablespoon of rum; mix well. Whip egg whites until stiff peaks form; fold into mascarpone cheese mixture. Spread 1/2 of mixture over soaked lady fingers. Cover with second half of soaked lady fingers and cover evenly with remaining mascarpone cheese mixture. Sprinkle with cocoa powder. Refrigerate at least 3 hours.
