Preheat your oven to 150 degrees fan bake (or 170 degrees regular bake).
Line a large baking tray with baking paper. The tray should be approx 20cm x 28cm
In a large bowl, place your grated butter and flour. Use your fingertips to rub the butter into the flour until the mixture resembles coarse breadcrumbs.
Add the baking powder, sugar and salt before giving this a quick mix together to combine
Add the yogurt, milk and vanilla to your bowl and mix well. The mixture should now be a coarse dough that forms together when pressed.
Roll dough out on a floured surface until it is a large rectangle about 1cm thick.
Place the brown sugar and spices into a small bowl and mix to combine.
Melt the butter and spread it over the entire surface of the rolled out dough.
Sprinkle all of the cinnamon sugar evenly over the buttered surface.
Gently start rolling up your dough. Start along the long back edge and continue rolling loosely until you have a long spiraled roll.
Using a serrated knife cut off your scrolls. Theses should be 2-3cm thick.
Arrange on a lined baking tray and brush over your cream. Pour any leftover cream over the scrolls.
Bake at 150 degrees fan for 35 mins or until just golden.
Mix up your glaze using enough milk to make it a pouring consistency.
Drizzle the over icing and serve hot or cold.
