Preheat the oven to 375°F (190°C). Line two baking sheets with parchment paper.
Make the filling: In a medium bowl, combine pumpkin puree, brown sugar, granulated sugar, egg yolks, and 2 teaspoons of homemade pumpkin spice blend. Mix well until smooth.
Prepare the crescent rolls: Open the tubes and separate each triangle. Place 1-2 tablespoons of pumpkin filling onto the wide end of each triangle. Spread the filling about two-thirds up towards the point, leaving the narrow tip clean.
Roll them up: Starting at the wide end, roll each crescent dough piece toward the point. Place on the prepared baking sheets, leaving at least 1-inch space between rolls.
Bake: Bake for 10-12 minutes or until golden brown.
Cool: Remove from the oven and transfer to wire racks. Let them cool for about 10 minutes.
Make the frosting: In a small bowl, whisk together powdered sugar, teaspoon of your homemade pumpkin spice blend, and 1 tablespoon of heavy cream. Add more cream if needed to achieve a drizzle consistency.
Drizzle: Use a spoon to drizzle the frosting over the cooled rolls. Serve and enjoy!
