Cake, nuts, tofu, tripe… (5,4)
I believe the answer is:
petit four
'cake' is the definition.
(petit four is a kind of cake)
'nuts tofu tripe' is the wordplay.
'nuts' is an anagram indicator (nuts can mean crazy).
'tofu'+'tripe'='tofutripe'
'tofutripe' with letters rearranged gives 'PETIT FOUR'.
(Other definitions for petit four that I've seen before include "Small fancy cake" , "Item of confectionery" , "Small cake, often decorated with marzipan" , "Bite-sized fancy cake" , "cake or biscuit" .)
