Frozen treats (4)
I believe the answer is:
ices
'frozen treats' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ices that I've seen before include "summer refreshment" , "Decorates cake with sugar topping" , "Frozen sweets" , "Decorates cakes with frosting" , "Cold refreshments" .)
