Set your oven to 350°F (175°C). Line baking sheets with parchment paper for easy cleanup.

In a large mixing bowl, beat the softened butter with powdered sugar until light and fluffy. Mix in the vanilla extract.

Gradually add the flour and salt, mixing just until combined. Fold in the finely chopped nuts using a spatula.

Scoop about 1 tablespoon of dough, roll it into a ball, and place it onto the prepared baking sheet. Repeat, spacing the cookies about 1 inch apart.

Bake in the preheated oven for 12-15 minutes, or until the cookies are set but not browned. Keep an eye on them to avoid overbaking.

Allow the cookies to cool for about 5 minutes on the baking sheet before transferring them to a wire rack. While still warm, roll the cookies in powdered sugar to coat them fully.

Once completely cooled, roll them in powdered sugar again for a snowy finish.
