Preheat your oven to 350°F (175°C).

In a large mixing bowl, combine the softened butter and 1/2 cup of powdered sugar. Beat together until light and fluffy, about 2-3 minutes.

Stir in the vanilla extract, then gradually add the flour and salt, mixing until fully combined.

Fold in the finely chopped nuts.

Roll the dough into 1-inch balls and place them on an ungreased baking sheet about 2 inches apart.

Bake in the preheated oven for 10-12 minutes or until the edges are light golden brown.

Let the cookies cool for about 5 minutes on the baking sheet, then roll them in powdered sugar while still warm.

Allow to cool completely on a wire rack before serving.
