1. Sprinkle on a baking paper, lay out the puff pastry, and then sprinkle on more cinnamon and sugar. 2. Fold over both edges, sprinkle with more cinnamon sugar, and use a rolling pin to roll flat. Fold over again and repeat this process until the edges almond meet, leaving 2 cm space open in between. 3. Fold the two edges on top of each other until you have a pretty folded envelope, chill the dough for about 30-60 minutes, and slice into 1cm cookies. 4. Place on a parchment paper-lined tray, bake for 20-30 minutes at 180 degrees Celsius, flip halfway over, and bake again until golden brown. 5. Serve and enjoy!
