Take in dessert (4)
I believe the answer is:
fool
This clue is a double definition.
'take in' is the first definition.
('fool' can be a synonym of 'take in')
'dessert' is the second definition.
(I've seen this before)
(Other definitions for fool that I've seen before include "Deceive" , "Ass - sweet" , "Sweet - trick" , "Charlie" , "Jester - dessert" .)
