Party raver’s target of the munchies? (5)

I believe the answer is:

donut

I'm a little stuck... Click here to teach me more about this clue!

'the munchies?' is the definition.
I can't tell whether this definition defines the answer.

'party raver's target' is the wordplay.
'party' becomes 'do' (do can informally mean a party).
'raver's target' becomes 'nut' (I can't justify this - if you can you should believe this answer much more).
'do'+'nut'='DONUT'

'of' acts as a link.

Can you help me to learn more?

(Other definitions for donut that I've seen before include "Fast food snack" , "American treat?" , "treat for Homer Simpson" , "American pastry" , "cake in the American way" .)

I've seen this clue in The Independent.
