Cut the butter into thin slices and put it in the fridge. I use a cheese slicer.
Warm the milk to finger warm, and stir the yeast into the warm milk. Add sugar and mix it. Then add flour and knead the dough until it is smooth and even. I use the mixer to knead the dough.
Bring flour to the table and roll out the dough into a rectangle of approximately 25 × 35 cm.
Spread the cold slices of butter on 2/3 of the dough.
Fold the 1/3 part of the dough without butter over half of the butter. Brush off excess flour well, we do not want flour inside the pastry dough. Press the dough together a little at the edges so that the butter is completely closed inside the dough.
Then fold the last 1/3 part with butter over the second folding, so you now have 3 layers of dough with butter in between. Press the dough together at the edge so that the butter is closed inside. Refrigerate the dough for 30 minutes to keep the butter cold and prevent it from melting.
2nd Folding - After 30 minutes, take the dough out of the fridge and roll it out again on a floured table. Fold the dough again in 1/3 parts as before, but this time you don't put butter in, it is already in between the layers. Once you have folded the first 1/3 part in over the middle and then the other 1/3 part in over the first, you will have 9 layers of dough. Now put the dough in the fridge for 30 minutes again.
3rd Folding - After 30 minutes, take the dough out of the fridge and roll it out again on a floured table. Fold the dough again as during the 2nd fold. When you have folded the dough this time, you have 27 layers with butter in between, and we are ready to make buns from the dough. Put the dough in the fridge for 15 minutes while you make the remonce that needs to be inside the buns.
