Fancy flapjack (5)
I believe the answer is:
crepe
'fancy flapjack' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for crepe that I've seen before include "Crinkly paper" , "Thin twenty four Ac" , "Crinkly fabric and French pancake" , "Crinkled fabric - black armband - thin pancake" , "Pancake - type of paper" .)
