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

'a lot' is the definition.
(oodles means a large amount)

I cannot understand how the rest of the clue works.

(Other definitions for oodles that I've seen before include "Large number or amount" , "a feast" , "Informally, great quantities" , "'Loads, lots (6)'" , "Lots (colloq.)" .)

I've seen this clue in the Evening Standard.
