Got any bananas to go with bread and butter? (5-4)

I believe the answer is:

nanny-goat

I'm a little stuck... Click here to teach me more about this clue!

'butter?' is the definition.
(animal which butts)

'got any bananas to go with' is the wordplay.
'bananas' indicates anagramming the letters (informal term for mad).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'go with' becomes 'nan' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'got'+'any'='gotany'
'gotany' with letters rearranged gives 'nygoat'.
'nygoat' after 'nan' is 'NANNY-GOAT'.

'bread and' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?
