Line the bottom of the baking dish with ladyfingers. Brush or soak twice with the coffee and once with the amaretto. Mix the sugar with the amaretto. Stir in the mascarpone and whipped cream. Spread half of this cream on the ladyfingers. Put the biscuits again and soak them like the first layer. Now spread the rest of the cream on top and let it steep in the refrigerator for at least 3 hours, or better overnight.
