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.
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!
Contains Raw Eggs: The Food Network Kitchen suggest caution in consuming raw and lightly cooked eggs due to the slight risk of salmonella or other food-borne illness. To reduce this risk, we recommend you use only fresh, properly refrigerated, clean grade A or AA eggs with intact shells, and avoid contact between the yolks or whites and the shell. For recipes that call for eggs that are raw or undercooked when the dish is served, use shell eggs that have been treated to destroy salmonella, by pasteurization or another approved method.
