Preheat oven to 375 degrees F and line a baking sheet with parchment paper
Lay the puff pastry on the parchment paper and spread the pumpkin butter in the center (about the same size as the brie wheel)
Place the brie wheel on top of the pumpkin butter
Wrap the puff pastry around the brie and pinch the edges to seal
Flip the puff pastry wrapped brie over so the flat surface is on top and wrap the kitchen twine around the brie to create the pumpkin indentions.
Brush the puff pastry with the whisked egg using a pastry brush
Bake for 35 minutes or until the puff pastry is a light golden color
Allow the Baked Brie to cool for 5 minutes and then carefully cut and remove the twine from the baked brie
Garnish with a cinnamon stick and sage leaf to create the pumpkin design
Serve immediately! Enjoy!
