Roll out the puff pastry and cut in half (short side). Brush one side with Nutella. How much Nutella you use is up to you, but I recommend not overpowering.
Put the other half on top. Cut again in the middle and leave it that way.
Then cut strips 1.5 - 2 cm wide. Then simply turn the individual strips and place them on a baking sheet lined with baking paper. Bake at 200 ° C (top / bottom heat, gas: level 3) in a preheated oven for 15-20 minutes.
