'confectionery' is the definition.
I know nothing about this answer so I can't judge whether this works.

'plonk son charlie on the counter' is the wordplay.
'plonk' becomes 'wine' (I've seen this before).
'son' becomes 's' (genealogical abbreviation for son).
'charlie' becomes 'mug' (I've seen this before).
'on the counter' says the letters should be written in reverse (counter can mean in the opposite direction).
's'+'mug'='smug'
'smug' written backwards gives 'gums'.
'wine'+'gums'='WINE GUMS'

'for' acts as a link.
