Sort of scalier cakes (7)
I believe the answer is:
eclairs
'cakes' is the definition.
(eclair is a type of cake)
'sort of scalier' is the wordplay.
'sort of' is an anagram indicator.
'scalier' with letters rearranged gives 'ECLAIRS'.
(Other definitions for eclairs that I've seen before include "Choux pastries with cream and chocolate icing" , "in which la creme may be found?" , "Cream cakes" , "Oblong cream puffs" , "Oblong pastries" .)
