Preheat your oven to 375 degrees fahrenheit. Line a baking sheet with parchment paper and set aside.
In a large mixing bowl, whisk together pumpkin puree, sugar, brown sugar, pumpkin pie spice, vanilla, and egg yolks. Keep mixing until well combined.
Roll 1 tube of crescent roll dough out onto a large cutting board or mat
Use a pizza cutter or knife to cut each crescent roll in half. For easier assembling, separate all of the crescents before beginning to add the filling.
Add 1 tbsp. Of the pumpkin mixture to each triangle, smoothing the mixture around to cover the crescent roll dough.
Roll the crescents starting from the wider end.
Place the rolled crescents onto the parchment paper.
Repeat until all of the crescents have had filling added and been rolled.
Bake for 10-12 minutes until crescents begin to turn golden brown.
Remove from the oven and cool completely. Before serving, dust the tops with powdered sugar.
