Preheat your oven to 375°F (190°C).
In a bowl, mix together the pumpkin puree, brown sugar, softened cream cheese, and pumpkin spice until smooth and well combined.
Roll out the thawed puff pastry sheet on a lightly floured surface to prevent sticking. If the pastry is too thick, roll it out slightly to achieve a thinner layer.
Evenly spread the pumpkin mixture over half of the puff pastry, leaving a small border around the edges to prevent the filling from spilling out.
Carefully fold the other half of the puff pastry sheet over the pumpkin filling, aligning the edges with the bottom half. Press down gently to seal the layers together.
Using a sharp knife or pizza cutter, slice the dough into strips about 1/2-inch wide. Starting from one end, gently twist each strip to create a spiral shape.
Place the twisted dough pieces onto a baking sheet lined with parchment paper. Brush each twist with melted butter.
In a small bowl, mix together the sugar and cinnamon. Sprinkle this mixture generously over the twists.
Bake in the preheated oven for 10-12 minutes, or until the twists are golden brown and puffed up.
Allow the twists to cool slightly before serving. Enjoy them warm, with a side of whipped cream for dipping if you’d like!
