On a work surface, sprinkle one-quarter of the cinnamon sugar. Place a sheet of puff pastry over the cinnamon sugar and roll out to a 12-inch square. Sprinkle with one-quarter of the cinnamon sugar.
Roll up one side tightly toward the middle. Then roll up the opposite side until both rolls meet in the middle. Press the two sides together gently. Repeat with the second puff pastry sheet and chill both for 30 minutes.
Once chilled, cut the chilled dough into ¼ to ½ inch slices. Lightly sprinkle cinnamon sugar onto both sides of the slice and lay it on a parchment-lined baking sheet. Give them plenty of room as they will increase in size!
Bake for 8-9 minutes, remove from the oven and flip to the other side. Bake for another 8 minutes or until golden brown and crisp. Cool on a cooling rack.
Notes
Storing: These are best eaten the day they are made, but they will keep for up to 3 days in an airtight container in the refrigerator.
Freezing: For the best results, freeze the shaped logs until ready to bake.
