Pastry (“lightning” in French) (6)

I believe the answer is:

eclair

(Other definitions for eclair that I've seen before include "teatime treat?" , "Torpedo-shaped cream cake" , "Cake, "long in shape but short in duration"" , "Long cream puff" , "A long choux cake" .)

I've seen this clue in The Sunday Times.
