These were such a delight! My first time making them and they were a hit!

Roll the Pastry: Starting from one of the long sides, tightly roll the pastry towards the center. Repeat this with the other long side until both rolls meet in the middle, creating a double-rolled log.
Slice & Arrange: Using a sharp knife, slice the rolled pastry log into 1/2-inch thick pieces. Place these slices, cut-side up, on one of the prepared baking sheets, leaving about 2 inches of space between each piece to allow for expansion.
Repeat & Bake: Repeat the process with the second sheet of puff pastry. Place both baking sheets in the preheated oven and bake for 12-15 minutes, or until the pastries are puffed up, golden brown, and crispy.
Cool & Serve: Remove from the oven and let them cool slightly on the baking sheets. The cinnamon sugar will be very hot. Serve warm and enjoy!
