For the filling : mix the brown sugar and cinnamon together. 

Mix sugar, 50ml milk and instant dried yeast together, let it rest for 10 minutes. In a large bowl, mix flour and salt together, then add in yeast mixture, mix well. Gradually add in milk to form a dough, you might not need to use all the milk.

Knead the dough for about 8 minutes or until the dough is smooth. You can also use stand mixer, beat on low speed for 5-8 minutes. 

Place the dough into slightly oiled bowl, cover with cling film and let it rest for at least 2 hours, the dough will double its size.

Divide the dough into 6 to 8 pieces, add in filling of your choice, seal it and roll into ball. Press a little bit. 

Add oil in hot pan, pan-fry the dough until both sides are golden. Enjoy!
