Dethaw puff pastry from freezer and set the oven to 400 degrees.

Mix the sugar and cardamom together and sprinkle 1-2 teaspoons on a clean surface. Place puff pastry on top of the sprinkled sugar. 

Pour the rest of the sugar on top of the puff pastry and spread evenly with your fingers. Make an even coating.

Roll out the sugar/puff pastry until the length has reached about 13 inches. No need to be precise. The point is to thin out the dough and introduce the sugar.

Fold the edge of one long side to the center of the dough. Repeat with the other side. Repeat this step on more time. Then finally, take one long side and fold it over the top of the other long end to make one long piece of dough.

Cut the sides to clean up the edges. Cut the cookies into 1/2 inch thick cookies and place on a cookie sheet with the inside faced up.

Bake for 12 minutes on one end then take out of the oven and flip the cookies on the other side. Continue to bake for 5-7 more minutes. 

Let cool before serving.
