Treat with tea (5)
I believe the answer is:
scone
'treat with tea' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for scone that I've seen before include "Small plain cake and Scottish town" , "baked cake" , "The Stone of -----, returned to Scotland in 1996 after 700 years" , "tea time treat" , "Cream tea cake" .)
