Cooked food consumed by my ape (6)
I believe the answer is:
copier
'ape' is the definition.
(thesaurus)
'cooked food consumed by my' is the wordplay.
'cooked food' becomes 'pie' (I've seen this before).
'consumed by' means one lot of letters goes inside another (inserted letters get consumed).
'my' becomes 'cor' (both are expressions of surprise).
'pie' placed inside 'cor' is 'COPIER'.
(Other definitions for copier that I've seen before include "Machine to reproduce print" , "Reproducer" , "unoriginal type" , "Something that duplicates" , "Machine for reproducing something" .)
