Either use the enclosed baking paper that comes with the ready rolled puff pastry or line a flat baking tray with a reusable liner or baking paper.
Spread the nutella or chocolate spread over the puff pastry sheet as shown in the picture.
Cut out a small star shape out of one corner and put to the side.
Unroll the second puff pastry sheet and place on top of the first one that is spread with chocolate.
Cut the pastry into the shape of a Christmas tree (triangle) with a wide base and trunk. Pull away the excess pastry.
Lightly score 2 lines down the middle of the triangle to form a tree trunk approx 3cm wide.
Cut branches into the sides of the triangle, approximately 2cm wide. Leave the top 5cm or so as this will be covered with your pastry star.
Taking each branch strip and turning it away from you twist each one a couple of times or so.
Brush all over with egg wash generously. Bake for about fifteen minutes until puffy and golden brown.
Dust with icing sugar for a festive finale.
