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

'biscuits' is the definition.
(shortbread is a kind of biscuit)

'money's needed after lacking' is the wordplay.
'money's' becomes 'breads' (bread is slang for money).
'needed after' means one lot of letters go next to another.
'lacking' becomes 'short' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'breads' put after 'short' is 'SHORTBREADS'.
