In the bowl of a stand mixer place water, yeast 1 cup of the flour, sugar, salt, 1 tbsp oil and milk powder. Combine to resemble a smooth batter. Set aside for 15 minutes.

Add in 1 cup remaining flour and 2 tbsp remaining oil. Add more flour as needed to form a smooth dough that is not sticky. Place formed dough in a well-oiled bowl and cover with clingwrap. Set aside in a warm spot to rise for an hour.

Mix all filling ingredients (soft butter, cinnamon powder, sugar and pecans) into a paste.

Remove cling wrap from the dough. Punch down the dough and roll out on a floured surface into a large rectangle about 4mm thickness. Spread filling mixture onto rectangle, leaving a 1cm border all around. Roll up the dough swiss roll style and pinch the seam closed.

Bake in a preheated oven at 180°C for 18-20 mins until golden brown on the top. Do not allow to dry out.
