Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
If using raw pecans, toast them in a dry skillet over medium heat until fragrant and lightly golden, about 5 minutes. Let them cool before chopping.
In a large mixing bowl, beat the softened butter and granulated sugar together until light and fluffy (about 2–3 minutes).
Beat in the egg yolk and vanilla extract until fully incorporated.
In a separate bowl, whisk together the flour and salt. Gradually add this mixture to the butter-sugar blend, mixing on low speed until a soft dough forms.
Step 5: Fold in Pecans
Gently fold in the finely chopped pecans until evenly distributed throughout the dough.
Step 6: Shape the Cookies
Scoop tablespoon-sized portions of dough and roll them into smooth balls.
Place the balls on the prepared baking sheet, spacing them about 2 inches apart.
Step 7: Bake
Bake in the preheated oven for 12–15 minutes, or until the edges are lightly golden but the centers remain soft.
Step 8: Roll in Powdered Sugar
While the cookies are still warm, carefully transfer them to a shallow dish filled with powdered sugar.
Gently roll each cookie in the powdered sugar until coated completely. Allow them to cool completely before handling further.
Step 9: Serve
