Cute small delicacies (6)
I believe the answer is:
sweets
'delicacies' is the definition.
(sweet is a kind of delicacy)
'cute small' is the wordplay.
'cute' becomes 'sweet' (I've seen this before).
'small' becomes 's' (abbreviation - e.g. clothes size).
'sweet'+'s'='SWEETS'
(Other definitions for sweets that I've seen before include "Pieces of confectionery" , "Prohibited food for dieters" , "Confectionery, candies" , "Confections, deserts" , "Sugar-based confections" .)
