Preheat oven to 400°F and line a baking sheet with parchment paper.
Slice strawberries and place in a medium sized bowl. Add 2 tablespoons of sugar and mix. Let this mixture sit.
In a medium bowl, combine room temperature cream cheese, 1 teaspoon vanilla extract and ½ cup powdered sugar. Mix to fully combine.
Gently unfold the thawed puff pastry, and cut into 6 even squares. You should have 12 total, after you use both sheets of puff pastry.
Score the dough around the edges, about ¼ inch away from the border and place about 1 tablespoon of the cream cheese filling in the inside. Smooth it out and place strawberries on top of the cream cheese filling.
Lightly beat the egg with a splash of water and brush around the border of the puff pastry. Sprinkle the whole pastry with sugar, if desired.
Place the prepared puff pastries in the freezer for 20 minutes. (You do not want to skip this step! It makes the crust puff up so nicely!)
Bake for 20-22 minutes at 400°F or until the crust is golden brown and puffy.
While the Danishes are baking, combine 1 cup of powdered sugar, 1 teaspoon of vanilla and 1-2 tablespoons of milk. You can drizzle this over the Danishes for a nice glaze.
Transfer to a cooling rack and top with glaze, and powdered sugar if desired.
