Step 1

Preheat oven to 450 degrees.

Step 2

In a small bowl, combine the sugars and cinnamon with a whisk.

Step 3

On a flat work surface, spread a thin layer of the sugar and unfold a sheet of pastry onto the sugar. Evenly spread a layer of sugar over the pastry being sure to coat the whole surface.

Step 4

With a rolling-pin, roll the dough until it's approximately 13x13 inches square.

Step 5

Fold the sides of the dough towards the center so they meet halfway in the middle. Fold the sides again so the two folds meet in the center and then fold 1 half over the other so it sits on top. You will have 6 layers.

Step 6

Slice the dough into 3/8-inch slices and place the slices, cut side up on a baking sheet lined with parchment paper.

Step 7

Repeat the process with the remaining sheet of puff pastry.

Step 8

Bake the cookies for 6 minutes until carmelized. Turn each over with a spatula and bake another 3-4 minutes.

Step 9

Remove from the oven and cool for 2 minutes and then transfer to a wire rack to cool completely.

Step 10

Store in an airtight container.
