Religious leader closed church wanting time for small box of buns (6,5)

'box of buns' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?

'religious leader closed church wanting time for small' is the wordplay.
I cannot really understand how this works, but
'leader' could be 'rabbi' (rabbi is a kind of leader) and 'rabbi' is found in the answer.
'church' could be 'ch' (common abbreviation) and 'ch' is found in the answer.
'time' could be 't' (abbreviation) and 't' is present in the answer.
The remaining letters 'hut' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
