Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper.
Place the brie in the center of the puff pastry sheet.
Cover the brie with prosciutto slices, wrapping around the sides.
Cut the remaining puff pastry into thin strips to create “mummy bandages.”
Wrap the strips over the brie, leaving small gaps to look like a mummy.
Brush lightly with beaten egg for a golden finish.
Bake for 20–25 minutes, until puff pastry is golden brown and crisp.
Let it cool slightly, then add olive or peppercorn “eyes.”
Serve warm with honey, fig jam, or crackers.
