Coffee go-with
I believe the answer is:
donut
'coffee go-with' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for donut that I've seen before include "ring coming across the Atlantic" , "Sugary deep-fried cake" , "Fast food snack" , "cake, American-style" , "cake in the American way" .)
