• 1 large egg: Combined into an egg wash for a glossy, golden crust.
• 1 tablespoon water: Thinned into the egg wash for easy brushing.

How To Make Buttery Flaky Baked Blackberry Turnovers

Let’s walk through the steps to achieve perfect, golden turnovers with jammy blackberry centers and crunchy sugar tops. From chilling and rolling your puff pastry to sealing each pastry pocket and finishing them off with melted butter, these instructions will guide you to flaky success.

1. Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper to ensure easy cleanup and even browning.

2. In a bowl, combine blackberries, granulated sugar, lemon juice, cornstarch, and salt; gently toss until every berry is coated in the sweet-thickening mixture.

3. On a lightly floured surface, unfold each pastry sheet and roll briefly to smooth seams, then cut each sheet into four equal squares for neat, uniform turnovers.

4. Whisk the egg with water to create an egg wash and set aside—this will give your pastries that irresistible golden shine.

5. Spoon equal portions of the blackberry mixture onto the center of each pastry square, leaving a small border for sealing.

6. Brush the edges of each square with egg wash, fold one corner over to form a triangle, and press edges firmly with a fork to ensure a tight seal.

7. Place turnovers on the prepared baking sheet, brush the tops lightly with egg wash, and score a small vent slit on each to let steam escape.

8. Bake for 18–20 minutes or until turnovers are golden brown and puffed to flaky perfection.

9. Remove from oven and immediately brush each turnover with melted butter, then sprinkle evenly with turbinado sugar for a sweet, crunchy crust.

10. Allow to cool slightly on a wire rack before serving to set the filling and maintain flakiness.
