For the Nutella bars, roll out the puff pastry and cut into strips about 2 cm thick.
Spread thinly with Nutella, take the puff pastry strip and turn in the opposite direction. Sprinkle with chopped hazelnuts.
Bake the Nutella bars for about 15 minutes at 180 °C hot air. Sprinkle with a little powdered sugar and serve.
Preparation Tip:
The Nutella sticks also taste great with jam.
