Preparation

• In a medium bowl, toss the sliced peaches with brown sugar, cinnamon, and vanilla extract. Let sit for 5–10 minutes while you prep the pastry.
• Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
• Unfold the puff pastry on a lightly floured surface and roll gently to even it out if needed. Cut into 6 equal squares.
• Place a few peach slices in the center of each square, leaving about a ½-inch border around the edges.
• Brush the edges with the beaten egg to help the pastry puff and brown.
• Transfer to the baking sheet and bake for 15–17 minutes, or until the pastry is puffed and golden brown.
• Remove from the oven and let cool for a few minutes.
• Dust with powdered sugar just before serving. Serve warm, optionally with a scoop of vanilla ice cream or a drizzle of honey.
• Brush with 1 tablespoon melted butter after baking (optional, to provide a more rich finish).
