Making Baked Cranberry Brie Bites is a delightful process! Follow these step-by-step instructions to create this incredible appetizer:

1. Preheat your oven to 375°F (190°C).
2. Roll out the thawed puff pastry on a lightly floured surface. Use a rolling pin if necessary to ensure it’s about 1/8 inch thick.
3. Cut the puff pastry into squares, approximately 3 inches by 3 inches.
4. Place a small piece of brie cheese in the center of each pastry square.
5. Top the brie with a spoonful of cranberry sauce, ensuring it doesn’t overflow.
6. Fold the corners of the pastry over the cheese and cranberry, pinching them together to create a small pouch. Alternatively, you can leave them open for a rustic look.
7. Place the filled pastry bites on a baking sheet lined with parchment paper.
8. Brush the tops of the pastry bites with the beaten egg to create a beautiful golden finish.
9. Bake in the preheated oven for 15-20 minutes, or until the pastry is golden brown and puffed.
10. Remove from the oven and allow to cool for a few minutes before transferring to a serving platter.
11. Optionally, sprinkle with chopped fresh rosemary for an aromatic touch before serving.

These straightforward steps will lead you to delightful Baked Cranberry Brie Bites that are sure to win over your guests.
