**Preheat Oven:** Preheat your oven to 325°F (163°C). Line a baking sheet with parchment paper or a silicone baking mat.

**Cream Butter and Sugars:** In a large mixing bowl, beat the softened butter, granulated sugar, and powdered sugar together until light and fluffy.

**Add Vanilla:** Mix in the vanilla extract until combined.

**Combine Dry Ingredients:** In a separate bowl, whisk together the flour and salt. Gradually add the dry ingredients to the butter mixture, mixing just until combined.

**Fold in Pecans:** Gently fold in the chopped pecans, ensuring they are evenly distributed throughout the dough.

**Shape the Cookies:** Scoop tablespoons of dough and roll them into balls. Flatten slightly with your palm and place them about 2 inches apart on the prepared baking sheet.

**Bake:** Bake for 18–20 minutes, or until the edges are lightly golden.

**Cool:** Allow the cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
