Make 1 recipe quick puff pastry. Keep in the freezer for 30 minutes.
Remove the puff pastry from the freezer. Coat the work surface with half of the sugar and roll out the dough into almost 12*10 inch (30*25cm) rectangle. Let the long side stays in front of you. Cover the top of the dough with the remaining sugar and use your rolling pin to stick the sugar to the dough. Fold almost 1,75 inches (4,5cm) from the top edge and the bottom edge. Repeat this step. Shortly, fold two times from the top edge and two times from the bottom edge equally until they almost meet in the center. Then fold one side over another.
Let the dough rest in the freezer for 30 minutes or until very cold.
Preheat the oven to 390°F(200C°). Line baking sheet with parchment paper or silicone baking mat.
Remove the dough from the freezer and cut into 0.4inch (1cm) thick slices. Place them on the baking sheet, at least about 2 inches (5cm) apart as they will spread during baking. Bake them for 7 minutes or until caramelized on the bottom and flip the palmiers over and bake for an additional 7 minutes or until they are golden brown.
