Follow these simple steps to create your own Mini Cheese Danish:

1. Preheat the Oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
2. Prepare Puff Pastry: Roll out the thawed puff pastry sheet on a lightly floured surface. Cut it into squares (about 3 inches each).
3. Make the Filling: In a mixing bowl, combine the softened cream cheese, granulated sugar, vanilla extract, egg yolk, and lemon juice. Mix until smooth and creamy.
4. Assemble the Pastries: Place a small spoonful of the cream cheese mixture in the center of each puff pastry square.
5. Fold the Pastry: Fold the corners of the pastry squares towards the center to create a pocket around the filling. Pinch to seal.
6. Egg Wash: Beat the egg and brush it over the tops of the pastries for a golden finish.
7. Bake: Place the pastries on the prepared baking sheet and bake for 15-20 minutes or until golden brown and puffed.
8. Cool: Remove from the oven and let them cool for 10 minutes on a wire rack.
9. Add Toppings: If desired, drizzle with icing or top with fresh fruit or jam before serving.
