Bread or dough? No big difference (5,6)
I believe the answer is:
small change
'difference' is the definition.
(I have seen 'little difference' mean 'small change' so perhaps 'difference' could also mean 'small change')
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for small change that I've seen before include "minor reorganisation" , "Money" , "Result of minor redesign" , "Minor alteration in" , "Minor coins" .)
