Sweet stuff, torte, parcelled oddly (7)
I believe the answer is:
treacle
'sweet stuff' is the definition.
(I've seen this before)
'torte parcelled oddly' is the wordplay.
'oddly' means one should take alternating letters.
'torte'+'parcelled'='torteparcelled'
The alternating letters of 'torteparcelled' are 'TREACLE'.
(Other definitions for treacle that I've seen before include "flattery" , "Carroll's sisters had to live with" , "Sweet, black viscous substance" , "cloying stuff" , "Golden syrup" .)
