Approx. 500 g / 18 oz / 1 lb mascarpone cheese
6 eggs
2 Tbsp sugar
Approx. 1.5 cups strong coffee
5 Tbsp coffee liqueur
2 Tbsp Rum extract
An ounce or two of dark chocolate
A package of savoiardi/ladyfinger biscuits
A few Tbsps of unsweetened cocoa powder
Beat 6 eggs in stand mixer with whisk attachment.
Add 2 Tbsp sugar.
Add mascarpone cheese and beat some more.
Add 1 Tbsp coffee.
Add 1 Tbsp coffee liqueur.
Set aside bowl of flavoured cream.
In a small bowl, mix 1.5 cup of coffee with 4 Tbsp coffee liqueur and 2 Tbsp rum extract.
Dip the lady finger biscuits in the coffee mixture and layer them on the bottom of your container. If your container is small, you may have to break a biscuit into smaller pieces. Then add a layer of cream on top of the biscuits. Then sift cocoa powder on top of the cream. Repeat these steps twice more so that you have three layers of each substance (or as many as is suitable for your container), ending with a layer of cocoa.
Fridge overnight or longer. When removing from fridge, grate dark chocolate over the top of each dish.

COMMENT:
I agree with adding Kahlua to the coffee (Tia Maria is a bit too sweet), although I think Toussaint is the best coffee liqueur all round.
For the cream I use 6 whole eggs to 2 cook's spoons of sugar; when that's beaten to a peaky consistency, I beat in 500g of mascarpone as lightly as possible after adding a slosh of Amaretto.
Over time I have tried all sorts of biscuit alternatives without marked success, so my failsafe is to use two layers of shop-bought flan sponge cases (sponge-cream-sponge-cream). These are firmer than homemade sponge and are very forgiving of the drizzled boozy coffee, plus they can be cut to fit the dish.
As for chocolate, pure cocoa powder sprinkled on each layer of sponge (after the coffee) then on the top layer of cream.
Nobody - and I mean NOBODY - has ever been anything other than complimentary after tasting my version.
