Creating the amazing Cranberry & Brie Flaky Pinwheels Appetizer is as easy as following these steps:

1. Preheat Oven: Begin by preheating your oven to 400°F (200°C).
2. Prepare Puff Pastry: Lightly flour your work surface. Unroll the thawed puff pastry sheet.
3. Spread Cranberry Sauce: Use a spatula to spread the cranberry sauce evenly over the entire surface of the pastry.
4. Add Brie Cheese: Layer the sliced brie cheese over the cranberry sauce, ensuring even distribution.
5. Sprinkle Herbs (Optional): If using, add the finely chopped rosemary or thyme on top of the brie for added flavor. Drizzle with honey for sweetness, if desired.
6. Roll the Pastry: From one end, carefully roll the pastry into a log shape. Be sure to roll tightly to ensure even pinwheels.
7. Slice for Pinwheels: Using a sharp knife, slice the log into ½-inch thick pieces to create the pinwheels.
8. Prepare Baking Sheet: Line a baking sheet with parchment paper.
9. Place Pinwheels: Arrange the sliced pinwheels on the prepared baking sheet, leaving space between each piece.
10. Egg Wash: Beat the egg in a small bowl and brush it over each pinwheel for a golden finish.
11. Bake: Place the baking sheet in the preheated oven and bake for 15-20 minutes or until the pinwheels are puffed and golden brown.
12. Cool and Serve: Once baked, allow the pinwheels to cool slightly before serving warm.
