Preheat your oven to 375°F (190°C). Get ready for some sweet baking!
Gently unfold the puff pastry on a lightly floured surface. Flouring is key for crispy layers.
1 sheet puff pastry
Using a heart-shaped cookie cutter, cut out as many hearts as possible. These are your base.
In a bowl, mix sliced strawberries with sugar and lemon juice. This macerates the strawberries, releasing their juices.
1 pound fresh strawberries, 2 tablespoons granulated sugar, 1 tablespoon lemon juice
Place half of the hearts on a baking sheet lined with parchment paper. These will be your base.
Carefully spread about a teaspoon of strawberry jam on each heart.
1/4 cup strawberry jam
Top the hearts with the marinated strawberries.
1 pound fresh strawberries
Place the remaining hearts on top of the strawberries and jam.
1 pound fresh strawberries, 1/4 cup strawberry jam
Brush each heart with beaten egg.
1 large egg
Bake for 15-20 minutes, or until the pastry is golden brown. Watch them carefully!
Let cool slightly on the baking sheet before transferring to a wire rack. Patience!
Dust with powdered sugar (optional). Now you can enjoy!
