Preparation Steps

• Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
• Lightly flour a clean surface and unfold the thawed puff pastry sheet. Sprinkle the sugar evenly over the puff pastry.

• Gently roll the puff pastry with the sugar to help it stick and to slightly thin it out. Fold the pastry in half, then in half again.
• Cut the folded puff pastry into 1-inch wide strips.
• Take one strip and make a diagonal cut about halfway down. Then, make another diagonal cut on the other side, creating a 'V' shape.
• Gently unfold the pastry to reveal the heart shape. Place the pastry hearts on the prepared baking sheet.
• Brush the tops of the pastry hearts with the beaten egg.
