Making the Delicious Blackberry Cream Cheese Danish is straightforward by following these seven simple steps:

1. Preheat Oven: Start by preheating your oven to 400°F (200°C). This ensures the perfect baking conditions for your pastry.

2. Prepare Cream Cheese Filling: In a mixing bowl, combine the softened cream cheese, granulated sugar, and vanilla extract. Beat until smooth and creamy.

3. Roll Out Pastry: On a lightly floured surface, roll out the puff pastry sheet into a rectangle, approximately 12×10 inches. Transfer to a lined baking sheet.

4. Make Cuts: Using a sharp knife, make diagonal cuts along the edges of the pastry, about 1 inch apart. Leave the center intact for the filling.

5. Spread Filling: Spoon the cream cheese mixture into the center of the puff pastry, then top with fresh blackberries, arranging them evenly.

6. Fold Pastry Strips: Fold the diagonal strips over the filling, alternating sides for a braided effect, pinching to seal as you go.

7. Bake: In a small bowl, whisk together the egg and milk. Brush this egg wash over the pastry for that brilliant golden color. Bake in the oven for 25-30 minutes until golden brown.
