01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - In a bowl, mix cream cheese, sugar, vanilla extract, and lemon zest until smooth and creamy.
03 - In another bowl, toss sliced strawberries with sugar and lemon juice. Set aside to macerate.
04 - Roll out the puff pastry on a lightly floured surface. Cut into 8 equal squares.
05 - Place each square on the prepared baking sheet. Score a smaller square inside each, being careful not to cut through the dough completely.
06 - Spoon about 1 tablespoon of cream cheese filling into the center of each square, spreading gently within the scored area.
07 - Arrange a few strawberry slices on top of the cream cheese filling.
08 - In a small bowl, whisk together the egg and milk. Brush the pastry edges lightly with the egg wash.
09 - Bake for 18-20 minutes, or until golden brown and puffed.
10 - Let danishes cool slightly. For the glaze, mix powdered sugar, milk, and vanilla extract until smooth, then drizzle over cooled danishes if desired.
