Preheat the oven to 375°F (190°C). Line a baking sheet with parchment paper.
In a small bowl, mix together pumpkin puree, brown sugar, maple syrup, and pumpkin spice.
Unroll the crescent dough on a cutting board and cut it in half to form two identical rectangles. Place one rectangle next to the other.
Spread the pumpkin mixture evenly over one rectangle of dough.
Place the second rectangle on top of the first, ensuring the edges line up, to sandwich the pumpkin mixture between them.
Use a pizza cutter to slice the layered dough into strips about 3/4 inch wide.
Transfer the strips to the prepared baking sheet. Twist each strip by picking up one end and twisting it twice, then doing the same at the other end.
Brush the twists generously with melted butter.
Combine the sugar and cinnamon, then sprinkle the mixture evenly over each twist.
Bake for 8-11 minutes, or until golden brown.
Serve warm with whipped cream for dipping, if desired.
