Round sweet (4-4)

I believe the answer is:

roly-poly

I believe this clue is a double definition.

'round' is the first definition.

'sweet' is the second definition.
(I've seen this before)

(Other definitions for roly-poly that I've seen before include "Kind of cylindrical jam pudding" , "Substantial" , "Plump and round" , "Plump in appearance- steamed pudding" , "Short and plump" .)

I've seen this clue in The Telegraph.
