Prepare the pastry

• Unroll the first sheet of puff pastry onto a baking tray lined with baking paper.
• Spread the Nutella evenly over the pastry, leaving a small border.
• Lay the second sheet of puff pastry on top and press gently to seal.

Cut the Christmas tree shape

• Cut the pastry into a Christmas tree shape, keeping the trunk at the base.
• Cut horizontal strips on both sides of the central trunk, leaving the middle intact.
• Twist each strip gently to create the branches.

Bake

• Bake in a preheated oven at 200 °C until golden and puffed.
• Leave to cool slightly before serving so the chocolate sets a little.
