Small ice creams and cakes (6)
I believe the answer is:
scones
'cakes' is the definition.
(type of small cake)
'small ice creams' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'ice creams' becomes 'cones' (ice cream cones).
's'+'cones'='SCONES'
'and' is the link.
(Other definitions for scones that I've seen before include "Small soft cakes of flour, fat and milk - eaten buttered" , "Small cakes of flour and fat, usually buttered" , "Small cakes made with flour, fat and milk" , "Rich biscuit-like pastry, best served with jam and butter" , "Basic components of cream teas" .)
