Prepare the puff pastry:

• Preheat your oven to 375°F (190°C).
• Lightly flour a surface and roll out the puff pastry.

Cut the pastry into 24 squares.

Assemble the bites:

• Place the pastry squares into a mini muffin tin, pressing gently to create cups.
• Add a cube of Brie cheese to each cup.
• Top with about 1 teaspoon of cranberry sauce.
• Sprinkle with chopped pecans if desired.

Bake:

• Place the muffin tin in the oven and bake for 12-15 minutes, or until the pastry is golden and puffed.

Garnish and serve:

• Add a small rosemary sprig to each bite for a festive touch.
• Serve warm or at room temperature.
