Preheat and Prepare:
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or lightly grease it to prevent sticking.
Cream the Butter and Sugar:
In a large mixing bowl, beat the softened butter and granulated sugar together until creamy and light, about 3-4 minutes. This will help create a light, fluffy cookie texture.
Add Wet Ingredients:
Add the egg and vanilla extract to the butter-sugar mixture, and beat until well combined.
Combine Dry Ingredients:
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Incorporate the Pecans:
Gently fold in the chopped pecans until they are evenly distributed throughout the dough.
Form the Cookies:
Using a cookie scoop or tablespoon, form small balls of dough, about 1 inch in diameter. Roll each ball of dough in the extra 1/4 cup of granulated sugar, coating them lightly.
Bake:
Place the dough balls onto the prepared baking sheet, spacing them about 2 inches apart. Flatten each ball slightly with the back of a spoon or your fingers for a more traditional cookie shape.
Bake for 10-12 minutes or until the edges of the cookies begin to turn golden brown. The centers will still be soft, but they will firm up as they cool.
Cool and Enjoy:
Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
