Small lightly sweetened cakes (6)
I believe the answer is:
scones
'small lightly sweetened cakes' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for scones that I've seen before include "Small cakes made with flour, fat and milk" , "Cakes for tea" , "Small unsweetened or lightly sweetened cakes" , "Small soft cakes of flour, fat and milk - eaten buttered" , "Basic components of cream teas" .)
