Benefits maintaining online work? Sweet! (12)
I believe the answer is:
profiteroles
'benefits maintaining online work? sweet' is the definition.
I know nothing about this answer so I can't tell whether this works.
'benefits maintaining online work? sweet' is the wordplay.
'benefits' becomes 'profits' ('profit' can be a synonym of 'benefit').
'maintaining' indicates putting letters inside.
'online' becomes 'e' (as in e-mail or e-commerce).
'work? sweet' becomes 'role' (I can't explain this - if you can you should give a lot more credence to this answer).
'e'+'role'='erole'
'profits' placed around 'erole' is 'PROFITEROLES'.
Can you help me to learn more?
(Other definitions for profiteroles that I've seen before include "Eclair-like dessert" , "Eclairs as a sweet" , "Small filled pastries" .)
