Sweet Potato Filling

There are three different filling for this bread. Mashed sweet potato with ginger, Mashed sweet potato with chocolate chip and again, Mashed sweet potato with coconut powder. I make the bread with the same method as the Black Sesame Bread.
It is not very clear from the picture to say there are three different fillings. But the taste is strong, especially the coconut. The smell and the taste, are the number one!
My knife ruin my bread! >.<
