vermouths

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

'drinks' is the definition.
(vermouth is a kind of drink)

'very endless cakeholes' is the wordplay.
'endless' means to remove the last letter.
'cakeholes' becomes 'mouths' (I am not sure about this - if you are sure you should believe this answer much more).
'very' with its last letter removed is 'ver'.
'ver'+'mouths'='VERMOUTHS'

'for' acts as a link.
