Warm the milk until lukewarm.
In a bowl, mix bread flour, sugar, salt, and yeast together.
Add the warm milk and room temperature butter, and knead the dough.
Let the dough rise for 1 hour (first proofing).
Roll out the dough into a square shape, roll it up, and place it in a loaf pan.
Let it rise again for about 40 minutes (second proofing).
Bake in a preheated oven at 180°C for 30 minutes.
