Preheat oven to 400 °F (200 °C) and line a baking sheet with parchment paper.

Lay one sheet of thawed puff pastry on a cutting board and cut the square into six rectangles (≈ 3 × 5 in or 8 × 12.5 cm).

Evenly scatter half the chocolate chips over those rectangles.

Roll each rectangle from the short end, enclosing the chocolate chips. Repeat with the second pastry sheet and remaining chips.

Place rolls seam‑side down on the prepared baking sheet. Wikipédia+12Marcellina In Cucina+12TikTok+12
