Preheat the Oven: Set your oven to 400°F (200°C).

Prepare the Baking Sheet: Line a cookie sheet with parchment paper.

Cut the Puff Pastry: Slice your puff pastry into 6 rectangles.

Arrange on the Sheet: Place the pastry rectangles on the prepared cookie sheet, ensuring there's a couple of inches of space between each one.

Prick the Pastry: Using a fork, prick the center of each pastry rectangle, leaving about ½ inch from the edges unpricked.

Prepare the Filling: In a bowl, combine the strawberry jam and softened cream cheese until well mixed.

Add the Filling: Divide the strawberry cream cheese mixture evenly among the pastries, spreading it over the center of each pastry and leaving about ½ inch from the edges.

Top with Strawberries: Place the sliced strawberries on top of the cream cheese mixture.

Brush with Butter: Lightly brush the edges of the pastries with melted butter. If you don't have a brush, you can use a paper towel dipped in melted butter to brush along the edges.

Bake: Bake the pastries in the preheated oven for 13-17 minutes, or until they are puffed and golden brown.

Serve: Remove the pastries from the oven and serve immediately.
