Lots of candied cake decoration - lovely (7)
I believe the answer is:
angelic
'lovely' is the definition.
(thesaurus)
'lots of candied cake decoration' is the wordplay.
'lots of' means to remove the last letter (the majority of the word).
'candied cake decoration' becomes 'angelica' (I've seen this before).
'angelica' with its last letter taken away is 'ANGELIC'.
(Other definitions for angelic that I've seen before include "Saintly" , "Virtuous" , "in the manner of Gabriel?" , "Of innocent beauty" , "Divine" .)
