Preheat your oven to 350°F (175°C). Gather ingredients and prepare your workspace.

Combine cranberries, brown sugar, maple syrup, vanilla extract, lemon juice, and cinnamon in a medium saucepan. Heat for 5–7 minutes.

Stir in the chopped pecans once cranberries have cooked down nicely.

Roll out puff pastry on a floured surface until about ¼ inch thick. Cut into a square large enough to wrap brie.

Spoon the warm cranberry-pecan mixture over the brie.

Carefully fold the puff pastry over the brie, sealing all openings.

Transfer the brie onto a parchment-lined baking sheet and bake for 15–20 minutes.

Allow to cool for 5 minutes before serving with crackers or baguette slices.
