Money that's provided by baker (5)
I believe the answer is:
bread
'money' is the definition.
(bread is slang for money)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for bread that I've seen before include "Eg, sourdough or rye" , "Food; money (informal)" , "Staple food" , "Dosh - a bloomer, perhaps?" , "Lolly - basic food" .)
