Prepare the pastry

• Unroll the puff pastry on a lightly floured surface and roll it out slightly.
• Cut the pastry into tree shapes, or cut triangles of increasing size to stack into trees.

Fill with Nutella

• Spread the Nutella over half of the pastry shapes.
• Top with the remaining shapes and press the edges gently to seal.

Shape the trees

• Cut horizontal slits along both sides of each triangle to create branches.
• Twist each strip gently and place the trees on a lined baking tray.

Brush and bake

• Brush the trees with the beaten egg.
• Bake in a preheated oven at 180 °C until golden and puffed.

Finish

• Let the trees cool slightly, then dust with powdered sugar.
