Spongy cake/bread roll (6)
I believe the answer is:
muffin
(Other definitions for muffin that I've seen before include "Round bread-like cake" , "Round raised cake, often split and toasted" , "Flat round cake, eaten toasted and buttered (6)" , "Flat, circular bread roll, eaten toasted and buttered" , "Yeast roll for toasting" .)
