Trap found in a Bundt (8)
I believe the answer is:
cakehole
I believe this clue is a double definition.
'trap' is the first definition.
(both can informally mean someone's mouth)
'found in a bundt' is the second definition.
(Bundt is a type of cake with a hole in it)
(Other definitions for cakehole that I've seen before include "What a doughnut might have" , "Gob (slang)" , "Echo leak (anag) - gob" , "Mouth (slang)" , "Chops" .)
