Preheat oven to 400°F and line two large baking sheets with parchment paper.
Unroll the puff pastry onto a lightly floured surface and slice in half, lengthwise. Then, cut each strip in quarters so you have eight large rectangles. Repeat with the second sheet of pastry.
17.3 ounces frozen puff pastry
Using a small paring knife, create a ½-inch border around the edge of each piece of puff pastry, but make sure not to cut all the way through!
Poke the center square of the puff pastry a few times with a fork-- this will ensure the edges rise, but not the center. This will help hold the filling in the Danish.
In a small bowl, stir the softened cream cheese, ¼ cup sugar, and vanilla together.
8 ounces cream cheese, 5 tablespoons granulated sugar, ½ teaspoon pure vanilla extract
In another bowl, stir the remaining 1 tablespoon sugar, chopped strawberries, and lemon juice together.
2 cups finely chopped fresh strawberries, 1 teaspoon fresh lemon juice
Divide the cream cheese mixture between the pieces of puff pastry (about 17 grams per pastry), making sure to only fill within the border.
Spoon the strawberry mixture over the cream cheese (about 22 grams per pastry).
Bake for 15-18 minutes, or until the edges are golden brown.
