This step is optional, but I prefer to work with warm ingredients :)

12. Sprinkle some flour over the dough and invert it out onto a floured worktop.

13. Flatten the dough with your palm to remove the trapped air.

14. Divide the dough into 9 portions, each weighs about 50g.

15. Shape the 9 doughs into balls by pulling down the sides and tuck at the bottom. Coat with some flour, covers with a lid and let them rest for 15 minutes.

16. Roll out a dough into a 10 cm diameter round flat dough.

Place a dollop of sweetened coconut in the middle. Wrap up the dough and seal at the bottom. Roll to shape.

    1. Hi Elaine, thank you for leaving your nice comment. You reminded me it has been quite some time since I last baked a sweet potato bread, haha :)

  4. Hi NgaiLeng for d coconut filling can I use gula melaka instead of white sugar ?

    1. Hi Sing Yee Fong, yes, you can use gula melaka in place of white sugar. I use white sugar because I want the colour contrast between the bread and the filling :)
