Italian dessert made with sponge soaked in coffee and Marsala, soft cheese and powdered chocolate (8)
I believe the answer is:
tiramisu
(Other definitions for tiramisu that I've seen before include "It. dessert, literally pick me up" , "Rich dessert, it is a rum (anag.)" , "Italian dessert with coffee and liqueur" , "Rich Italian dessert" , "Dessert -- is it arum? (anag)" .)
