Choux pastries with cream and chocolate icing (7)
I believe the answer is:
eclairs
'choux pastries with cream and chocolate icing' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for eclairs that I've seen before include "Cream cakes" , "in which la creme may be found?" , "sticky fingers" , "Oblong cream puffs" , "Oblong pastries" .)
