Step 1: Preheat & Prepare

1. Preheat your oven to 375°F (190°C).
2. Line a baking sheet with parchment paper for easy cleanup.

Step 2: Make the Filling

1. In a bowl, mix the cream cheese, granulated sugar, vanilla extract, egg yolk, and lemon zest until smooth and creamy.

Step 3: Prepare the Dough

1. If using crescent roll dough, unroll it and pinch the seams together to form a single sheet.
2. If using puff pastry, roll it out slightly on a floured surface.
3. Cut the dough into six equal rectangles or triangles, depending on your preferred shape.

Step 4: Assemble the Danish

1. Place 1 tablespoon of cream cheese filling in the center of each dough piece.
2. Fold or twist the edges to partially enclose the filling, leaving some of it exposed for a classic Danish look.
3. Lightly brush the dough with milk or heavy cream to give it a golden finish.

Step 5: Bake

1. Transfer to the prepared baking sheet and bake for 12-15 minutes, or until the Danishes are golden brown and puffed.

Step 6: Prepare the Icing (Optional)

1. In a small bowl, whisk together powdered sugar, milk, and vanilla extract until smooth.
2. Drizzle the icing over the cooled Danish for an extra sweet touch.

Step 7: Serve & Enjoy

1. Let the Danishes cool slightly before dusting with powdered sugar.
2. Serve warm or at room temperature with a cup of coffee or tea.
