Lay one sheet of puff pastry dough in a baking tray lined with parchment paper. Use a spoon or knife to evenly spread the hazelnut cream, then lay the second sheet on top.
Now cut the shape of a tree, then cut the sides into branches that are about 1-1.5 cm (½-¾ inch wide). Use cookie cutters to use up the remaining dough. Then brush the tree and other shapes with the eggwash for the golden shine
Bake everything for 15-20 minutes on 180°C (356°F) ore until golden. Sprinkle some icing sugar on top to give the illusion of snow. Enjoy!
