Flaky dessert (3)
I believe the answer is:
pie
'flaky dessert' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pie that I've seen before include "Filled pastry" , "Pecan or blueberry dish?" , "See 6" , "In the sky, it's an empty promise" , "Cooked food" .)
