Rubbish batch of small buns? (6)
I believe the answer is:
litter
'rubbish' is the definition.
(litter is a kind of rubbish)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for litter that I've seen before include "Animal young, stretcher and rubbish" , "Rubbish left lying about in public" , "Number of animals born to the same mother at the same time" , "junk" , "Discarded rubbish" .)
