Sweet animal artist's captured (7)
I believe the answer is:
caramel
'sweet' is the definition.
(caramel is a kind of sweet)
'animal artist's captured' is the wordplay.
'animal' becomes 'camel' (I've seen this before**).
'artist' becomes 'ra' (Royal Academician, member of Royal Academy of Arts).
'captured' is an insertion indicator.
'camel' placed around 'ra' is 'CARAMEL'.
(Other definitions for caramel that I've seen before include "Soft toffee" , "Cooked sugar" , "Soft sweet" , "Chewy sweet - burnt sugar" , "Chew candy" .)
