Ice-cream with fruit and nuts (7)
I believe the answer is:
cassata
'ice-cream with fruit and nuts' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for cassata that I've seen before include "Italian ice cream dish" , "Ice-cream with fruit and nuts" , "Ice-cream dish" , "Neapolitan ice cream containing candied fruit" , "Neapolitan ice-cream" .)
