How to Make-Ahead & Freeze: Follow the instructions as above, but under-bake the pastry swirls slightly, until just a touch golden. Allow them to cool completely, and then remove each from the muffin tin, placing them on a baking sheet covered in parchment paper so that they do not touch. Place the tray in the freezer until frozen, about 2 hours. Once completely frozen, transfer the pastry swirls to a large Ziploc bag and store in the freezer. When ready to serve, do not thaw, but bake from frozen on a sheet of parchment paper in the oven at 350°F for 10-15 minutes. Use within 2 months.
