Cookie's wanting money (10)

I believe the answer is:

shortbread

'cookie's' is the definition.
(shortbread is a kind of cookie)

'wanting money' is the wordplay.
'wanting' becomes 'short' (I've seen this before).
'money' becomes 'bread' (slang term for money).
'short'+'bread'='SHORTBREAD'

(Other definitions for shortbread that I've seen before include "Biscuit with plenty of butter" , "biscuits" , "Crumbly biscuit rich in butter" , "sweet but easily crumbling" , "Brittle buttery cake" .)

I've seen this clue in the Sydney Morning Herald.
