Whisk egg whites until foamy. Pour in 1/4 of sugar and continue to whisk until soft peaks form. Set mixture aside.
In another bowl, combine egg yolks and 1/4 cup of sugar. Whisk until it turns into a pale yellow color and is thick. Whisk in the mascarpone cheese until smooth. Fold in the egg white mixture until fully combined.
In a shallow bowl combine the coffee and Kahula together. Dunk the lady fingers 1 at a time for 1-2 seconds in the mixture and create 1 layer in a 13×9 baking dish (you may have to break some in half in order for it to all fit). Add 1/3 of the mascarpone mixture on top of the first layer of lady fingers and spread it out evenly. Add a few tablespoons of grated chocolate on top. Repeat the process 2 more times in order to get 3 layers.
Cover with plastic wrap and chill in the refrigerator for at least 3 hours (over night is best).
Dust the top with cocoa powder and the remaining grated chocolate.
