Preheat oven to 375°F and line a large baking sheet with parchment paper.
In a medium bowl, whisk together pumpkin puree, brown sugar, maple syrup, and 1 teaspoon pumpkin pie spice until smooth.
Unroll one can of crescent dough and press seams to form a rectangle. Spread half the pumpkin mixture evenly over dough, leaving small border.
Unroll second can of crescent dough, press seams, and place on top of pumpkin-covered dough to create sandwich.
Cut layered dough into 3/4-inch wide strips using pizza cutter. Transfer to prepared baking sheet, spacing 2 inches apart.
Twist each strip 2-3 times from each end. Brush generously with melted butter.
Mix granulated sugar, cinnamon, remaining 1 teaspoon pumpkin pie spice, and salt. Sprinkle over twists.
Bake for 10-12 minutes until golden brown and puffed. Cool slightly before serving.
