Put the flour to a large bowl. Make a hole in the middle and put the sugar and the warmed milk in it. Crumble the yeast in the milk and let it ferment for 15 mins.

Add the salt, cinnamon and the soft butter and knead it until the dough isn't sticky. Add more flour if necessary.

Cover the bowl with a clean cloth, and put it in a warm place for an hour. It shoul be doubled in volume by then.

Meanwhile melt the butter a little (don't make it too hot), and mix in the sugar and the cinnamon. Let it cool down.

Preheat the oven for 200 °C.

Roll the dough to an approx. 30x70 rectangular shape. Make it evenly thin. Smear the topping on it.

Roll up the dough, and slice it.

Put the slices on a paper lined tray, put it in the oven and bake until golden brown.
