Mix Filling Ingredients: In a medium bowl, beat the softened cream cheese, granulated sugar, egg yolk, and vanilla extract until smooth and creamy. Set aside.

Preheat Oven and Prepare Baking Sheet: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.

Prepare Crescent Dough: Open the cans of crescent roll dough and separate the dough into triangles. On the parchment-lined baking sheet, place the triangles with the wider part towards you, slightly overlapping the edges, and press together to seal, forming a rectangular shape. You can also shape them into individual Danishes by creating circles or squares, leaving a well in the center for the filling.

Add Filling: Spoon the cream cheese mixture onto the center of each prepared dough shape. If making a large rectangle, spread the mixture evenly across the dough, leaving a small border around the edges.

Create Egg Wash: In a small bowl, lightly beat the reserved egg white with a tablespoon of water.

Apply Egg Wash: Brush the edges of the dough with the egg wash. This will help to create a golden color upon baking.

Bake: Bake in the preheated oven for about 15-20 minutes, or until the Danishes are golden brown and the dough is fully cooked.

Mix Glaze Ingredients: While the Danishes are baking, prepare the glaze by whisking together the powdered sugar, milk, and vanilla extract in a small bowl. Adjust the consistency by adding more milk or powdered sugar as needed; the glaze should be thick but pourable.

Glaze the Danishes: Once the Danishes are slightly cooled, drizzle them with the glaze.

Serve the Crescent Cheese Danishes warm or at room temperature for the best taste and texture.
