In a large bowl combine the warm milk and the melted butter.
Sprinkle on the yeast. Let activate for 10 minutes.
Add the sugar and salt and stir.
Stir in the flour, ½ cup at a time.
When it is too thick to stir, transfer to a lightly floured surface and knead for a minute or so until it forms a ball.
Cover a medium bowl with a little oil and add the dough bowl in.
Cover with a kitchen towel and let it sit about an hour in a warm place, until double in size.
Preheat oven to 200C.
Divide the dough into 3 equal pieces.
Roll each piece into a circle.
Using a spatula, spread ½ of the warmed hazelnut spread on the bottom circle, cover with the second and repeat.
Cover with the last circle.
Using a large plate cut out the edges to create a perfect circle.
Transfer the dough to a baking tray with parchment paper.
To twist the dough, put a large cup in the center of the circle upside down.
Using a pizza knife, cut the dough from the cup to the edge into 16 wedges.
Twist the wedges together to form the star shape.
Top with some milk wash.
Bake for about 30 minutes.
