You can pack it with cooked bagel dough on top (6,3)
I believe the answer is:
duffel bag
'you can pack it' is the definition.
(a bag might be packed with items)
'cooked bagel dough on top' is the wordplay.
'cooked' indicates an anagram (letters cooked into a new form).
'dough' becomes 'duff' (dialect form of 'dough').
'on top' is a charade indicator (letters next to each other) (in a down clue, some letters go above others).
'bagel' is an anagram of 'elbag'.
'elbag' after 'duff' is 'DUFFEL BAG'.
'with' acts as a link.
(Other definitions for duffel bag that I've seen before include "Canvas carrier" , "One used to carry" , "Shoulder-worn canvas item with drawstring" .)
