01 - Preheat oven to 400°F. Line a baking sheet with parchment paper.
02 - On a lightly floured surface, unfold puff pastry. Using a 3-inch heart-shaped cookie cutter, cut out 16 hearts. Place 8 hearts on the prepared baking sheet.
03 - With the remaining 8 hearts, use a 2-inch heart cutter to cut out the centers, creating heart-shaped frames.
04 - Brush the edges of the whole hearts on the baking sheet with egg wash. Place the heart frames on top, gently pressing down to adhere.
05 - In a small bowl, mix cream cheese, sugar, and vanilla until smooth and creamy.
06 - Spoon about 1 tablespoon of cream cheese filling into the center of each heart. Top with 1/2 tablespoon strawberry preserves and a few slices of fresh strawberry.
07 - Brush the pastry edges with remaining egg wash for golden browning.
08 - Bake for 16-18 minutes until golden and puffed. Let cool on the baking sheet for 10 minutes.
09 - Whisk powdered sugar, milk, and vanilla until smooth. Drizzle over cooled danishes before serving.
