Preheat oven to 425 degrees F. Line a small baking pan with parchment paper and set aside.
Roll out the puff pastry and place the brie cheese wheel in the center.
Over the cheese wheel, place the apple butter and pecans.
Gently fold over the puff pastry over the cheese, apple butter and pecans. don't worry if there's overlap. Continue to wrap the cheese until sealed in puff pastry.
Cut four 15-17 inch pieces of butcher's food grade twine. Wrap the wheel in four evenly spaced pieces of twine so it resembles a pumpkin shape.
In a small bowl, whisk the egg and 1 tablespoon of water to make the egg wash. Brush the entire pastry with the egg wash. Place the pastry on the prepared pan.
Place the brie pastry in the oven and bake for 25 minutes or until golden brown.
Remove the baked brie from the oven and allow to cool for 5 minutes.
Carefully cut away and remove the kitchen twine.
Gently, push the cinnamon stick into the center of the pastry so it appears as the pumpkin stem.
Serve immediately.
