Sweets and chocolates (13)
I believe the answer is:
confectionery
'sweets and chocolates' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for confectionery that I've seen before include "Sweets, chocolate etc" , "Certify on cone (anag)" , "Sweets, chocolates, etc" , "Sugary stuff" , "sweet things" .)
