Thaw the frozen puff pastry sheets according to the manufacturer's instructions.

Preheat your oven to 400ºF/200ºC and line a baking sheet with non-stick parchment paper.

Lay one sheet of thawed puff pastry on a cutting board and cut it into 6 rectangles, approximately 3 inches by 5 inches.

Scatter half of the chocolate chips over each piece of pastry.

Starting from the short end, roll up each rectangle tightly while capturing the chocolate chips inside.

Repeat this process with the remaining pastry and chocolate chips.

Arrange the rolled pastries on your prepared baking sheet seam-side down.

Bake for about 20 minutes until golden brown and crispy.

Once baked, transfer them to a wire rack to cool completely.

Sieve powdered sugar over your pastries just before serving.
