US cookies (8)
I believe the answer is:
biscuits
'us cookies' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for biscuits that I've seen before include "Custard creams, for example" , "In the US, they're cookies" , "Small thin crisp cakes" , "Small flat sweet cakes" , "Maybe companions for tea" .)
