Easy Nutella Wreath

1. Spread a thin layer of Nutella onto the defrosted pastry dough, leaving 1 inch bare at the top. 
2. Roll the dough into a log and then cut it in half down the middle to create two long strands.
3. Twist the two strands together and then join them at the top to create a wreath shape. 
4. Brush the wreath with an egg wash (beat the egg with a little water) and sprinkle with flaky sea salt or sugar.
5. Bake at 350°F (175°C) for 30 minutes, then cover with foil and bake for an additional 20 minutes until golden brown and cooked through.
