I clear off for a cake (6)
I believe the answer is:
eclair
'cake' is the definition.
(eclair is a type of cake)
'i clear off' is the wordplay.
'off' is an anagram indicator.
'i'+'clear'='iclear'
'iclear' with letters rearranged gives 'ECLAIR'.
'for a' is the link.
(Other definitions for eclair that I've seen before include "Cream bun" , "Lacier (anag.)" , "Lacier type of confection" , "cream-cake" , "A long choux cake" .)
