Sweet kid (4)

I believe the answer is:

fool

I believe this is a double definition.

'sweet' is the first definition.
(type of dessert or sweet)

'kid' is the second definition.
(both can mean to jokingly trick)

(Other definitions for fool that I've seen before include "Dimwit" , "Jester; dupe" , "Dupe - dessert" , "Jester - dessert" , "Ass - sweet" .)

I've seen this clue in The Telegraph.
