In a small bowl, add flour, soft brown sugar, active dry yeast, and milk.
Mix well, and knead until smooth dough forms. We started using a hand mixer with a dough hook, and finish it off by hand kneading. We find the dough is a bit too small to handle with the hand mixer.
Add the butter, continue to knead until smooth dough forms again. If you stretch the dough, a thin translucent membrane is formed (aka windowpane).
Add the raisin, knead just enough to have them spread evenly.
Keep the dough covered in a warm place to rise for 45 mins, or until it doubles its size.
When the first proof is ready, punch all the air out from the dough. Shape it into a ball, cover it and let it rest for 10 mins.
Use a rolling pin to roll the dough into a large rectangle.
Spread some softened butter, cinnamon, and brown sugar.
Roll the dough into a long roll, from one short edge to another.
Use unflavored dental floss, cut the rolls, around 2 inches thick.
Leave the rolls on a baking pan, cover them in a warm place for the second rise, until it doubles its size - which takes around 30 mins.
Preheat the oven at 180°C.
Brush a little bit of milk on the cinnamon rolls before baking.
Bake for around 10-12 mins and the top should be goldened brown.
Transfer to a wire rack to cool down.
