Preheat oven to 400 degrees F.

Prepare a cookie sheet by lining it with parchment paper.

In a small bowl, mix sugar and cinnamon together.

On a clean surface, sprinkle half of the cinnamon/sugar mixture.

Gently unroll the pastry sheet over the sugar.

Sprinkle the remaining sugar mixture entirely over the dough.

With a rolling pin, roll the dough out so that it is about 1/2-1 inch longer on all sides so that it is approximately 10 X 12-inches.

Beginning with one of the longer sides, gently roll it towards the middle, stopping in the center of the dough.

Do the same with the other side, rolling into the center.

Gently press the two rolls together.

Wrap in plastic wrap, place on a cookie sheet and refrigerate for an hour until firm.

Remove from refrigerator and using a sharp knife, cut dough into 1/2 inch-thick slices and place on prepared cookie sheet about 1-2 inches apart.

Bake for 6 minutes, rotate the cookie sheet and then bake for another 6-8 minutes until golden.
