Preheat your oven to 375°F (190°C) and line a baking tray with parchment paper.
Lay the puff pastry flat on a clean surface.
Spread an even layer of Nutella over the pastry, leaving a small border.
Roll the pastry tightly from the long edge into a log.
Chill in the refrigerator for 10 minutes for easier slicing (optional).
Slice into 1.5 cm rounds using a sharp knife.
Place the swirls on the prepared baking tray, leaving space between each.
Bake for 15 minutes or until golden and crispy.
Allow to cool slightly, then serve your Nutella swirls warm or at room temperature.
