Pancake's in robusta coffee! (4)
I believe the answer is:
taco
'pancake's' is the definition.
(I've seen this before)
'in robusta coffee' is the wordplay.
'in' indicates a hidden word.
'TACO' is hidden in the letters of 'robusta coffee'.
(Other definitions for taco that I've seen before include "Mexican dish of rolled tortilla with filling" , "Mexican filled tortilla" , "Tortilla rolled round a filling" , "foreign food" , "Folded and filled tortilla" .)
