Dishes in Bake Off served with hollowed biscuits (6)
I believe the answer is:
kebabs
'dishes' is the definition.
(kebab is a kind of dish)
'bake off served with hollowed biscuits' is the wordplay.
'off' is an anagram indicator.
'served with' means one lot of letters go next to another.
'hollowed' says to hollow out the word (remove centre letters).
'biscuits' with its centre taken out is 'bs'.
'bake' anagrammed gives 'keba'.
'keba'+'bs'='KEBABS'
'in' acts as a link.
(Other definitions for kebabs that I've seen before include "Marinated meat cooked on skewers" , "Meat on skewers; ska ebb (anag.)" , "Turkish dishes of meat and veg on skewers" .)
