Place the 2 eggs and 2 whole egg yolks in an electric mixer bowl and add approximately 8 tablespoons of sugar. With whisk attachment beat until the mixture forms a good ribbon (should nearly have soft peaks). Once the correct consistency is achieved, whisk in the Mascarpone cheese. In a separate bowl, whip the cream along with 2 tablespoons sugar and a pinch of salt.
Once hard peaks form, add the whipped cream to the egg/Mascarpone mixture and beat until smooth, adding approximately 2 tablespoons Marsala.
In a separate bowl, pour the hot espresso and add 2 tablespoons sugar and 8 tablespoons Marsala.
Assembly: One at a time, quickly dip each biscuit in the espresso mixture and then place on the bottom of a 9 by 13 glass baking pan. Continue until you have an entire layer of biscuits on the bottom of the pan. (Note of Caution: Dip quickly or biscuits will become soggy.)
Using a spatula spread half of the mascarpone cream over the biscuits. Repeat the process above to make a second layer. This should fill the pan.
Finish: Refrigerate 8 to 10 hours or overnight. Grate the chocolate over the top. Enjoy!
