Cinnamon Roll with icing (5K Bread Dough)

This is one of the best bread dough I tried.

The bread is still soft on second day.

Icing- The butter had not fully softened yet.

Starter dough:

105g bread flour

45g cake flour

12g sugar

3g instant yeast

120g water

Main dough:

105g bread flour

45g cake flour

48g sugar

3/4 tsp salt

12g milk powder

45g egg

27g water

36g butter

Fillings: 

1-2 tbs cinnamon sugar (personal preference)

Icing ingredients:

1/2 cup icing sugar

1 tbs butter, softened

1/2 tsp vanilla extract

1 tbs milk

Mix all together

Method (yields 9 rolls):

1. Lightly grease the a 9 inch pan.
2. Mix the starter dough and allow to sit in a environment to rise till it looks like "honeycomb".
3. Mix the main dough ingredients except butter. The initial dough will be very wet, it will be fine after several kneading. Knead till is soft and non sticky, incorporate butter and knead till it don't stick to the side.
4. Allow the dough to rise till doubles in size.
5. Punch down and roll dough flat in square size.
6. Sprinkle cinnamon sugar on the dough, roll it like swiss roll. Cut it to 1.5inch thick.
7. Place inside pan and let it rise (around 45-60mins).
8. Preheat oven at 180degree, bake it at lower rack for 25mins.
9. Remove from oven, pour the icing glaze onto the roll and let it cool.
10. Glaze will hardens once it is cooled.
