Heat oven to 400F and grease a 12-cup mini muffin tin.

Cut the puff pastry into 12 squares and press one into each cup.

Stir the pumpkin, maple syrup, cinnamon, and salt together in a small bowl.

Tuck a brie cube into each cup and top with a small spoon of the pumpkin mixture.

Scatter pecans over the top and bake 16 to 18 minutes until puffed and golden.

Cool 5 minutes before lifting out so the cheese sets just enough to hold.
