Yes, you can! The pinwheels can be frozen un-baked or baked. Prepare the pinwheels as per normal. To freeze un-baked pinwheels, place them in a single layer on a flat tray and freeze until solid (around an hour). Then, transfer them to a freezer-safe bag or container and freeze for 2 months. Puff pastry scrolls can be baked straight from frozen, just add an extra 5 minutes to the cooking time. Alternatively freeze baked pinwheels in an airtight container for up to 3 months. Thaw in the fridge overnight before eating, hot or cold.
