Sweet clown (4)
I believe the answer is:
fool
I believe this clue is a double definition.
'sweet' is the first definition.
(type of dessert or sweet)
'clown' is the second definition.
(fool is a kind of clown)
(Other definitions for fool that I've seen before include "Sweet - kid" , "Jester or silly ass" , "Dupe - dessert" , "One and his money are soon parted" , "Ass - sweet" .)
