Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

Combine granulated sugar, light corn syrup, melted unsalted butter, vanilla extract, and a large egg in a mixing bowl. Whisk until smooth.

Stir in the chopped pecans until coated with the filling mixture.

Unroll the Pillsbury Crescent Rolls and separate into triangles on the baking sheet.

Spoon 2-3 tablespoons of the pecan filling on the widest end of each triangle and roll tightly.

Bake the rolls for 8 minutes until setting.

Brush with the reserved sugar mixture and bake for an additional 5 minutes until golden brown.

Allow to cool slightly and serve warm, optionally garnish with chopped pecans.
