First off, punch down the dough and divide the dough into 4 equal pieces.
Work with 1 piece at a time while keeping the remaining pieces covered with cling wrap.
On a lightly floured work surface and dusted rolling pin, roll out one piece of dough to an 8 to 10 inch circle. (This will depend on the size of your largest baking sheet as you'll need some growing space of about 2 inches more)
Transfer the rolled out dough to a parchment lined cookie sheet. (use a very large baking sheet)
Spread a third of the filling over the dough while pressing down lightly into the dough. (It gets messy and sticky but works out well. Simply wash your hands in between rolling the next round of dough.)
Sprinkle one teaspoon of cinnamon over the filling.
Roll out the second piece of dough and place directly over the first.
Top with some of the filling and sprinkle with another teaspoon of cinnamon.
Repeat with the third piece of dough. Roll out and place directly over the second round of dough,
Spread with the remaining filling and cinnamon.
Roll out the fourth piece of dough and place it over the third while pressing down gently. (this one will not have any filling over it)
Now we are ready to slice.
First, place a round cookie cutter or glass of about 2 ¼ inch wide over the centre of the stacked star bread.
With a sharp knife, cut the dough all the way through into four equal wedges while leaving the cookie cutter or glass in place.
Cute each wedge into 2 equal pieces while cutting all the way through. So now you have 8 pieces.
Cut each of the 8 pieces in half. And now you end up with 16 wedges all connected to the middle circle.
We are now ready to twist the wedges.
Grab hold of two wedges of dough that are side-by-side.
Twist the wedges away from each other making two whole twists and pinch the edges to seal.
Repeat with the remaining wedges to form the star bread.
Cover the star bread loosely with cling wrap and set aside in a draft free area for 30 minutes to rise slightly.
Preheat the oven to 350 degrees F.
Brush the star bread with the beaten egg.
Bake in the preheated oven for approximately 20 minutes.
When ready, the star bread will have a deep golden brown colour.
Let rest for about 30 minutes on a cooling rack.
Then serve while still warm from the oven topped with a dusting of powdered sugar.
