Long cream puff (6)
I believe the answer is:
eclair
'long cream puff' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eclair that I've seen before include "Type of cream cake" , "A long choux cake" , "Food" , "Lacier (anag.)" , "Torpedo-shaped cream cake" .)
