Best nuts and biscuits (5,8)

I believe the answer is:

cream crackers

'biscuits' is the definition.
(cream cracker is a type of biscuit)

'best nuts' is the wordplay.
'best' becomes 'cream' (both can mean the elite).
'nuts' becomes 'crackers' (both can informally mean mad).
'cream'+'crackers'='CREAM CRACKERS'

'and' acts as a link.

I've seen this clue in The Telegraph.
