Preheat your oven to 350°F (175°C). This step is crucial as it ensures that your cookies bake evenly, coming out perfectly golden and tender.

Cream the softened butter and powdered sugar together in a mixing bowl. Use a hand mixer or whisk until the mixture is smooth and fluffy, about 2-3 minutes.

Add the vanilla extract to the butter-sugar mixture. This will infuse your cookies with a delightful warmth and aroma as they bake.

Gradually mix in the all-purpose flour, finely chopped nuts, and salt. Stir until everything is well combined and forms a soft dough.

Shape the dough into small balls, about 1 inch in diameter. Place them nicely on a baking sheet lined with parchment paper to prevent sticking.

Bake the cookies in your preheated oven for 20 minutes or until the bottoms are lightly browned. The tops should remain pale and soft to maintain that melt-in-your-mouth texture.

Roll the warm cookies in powdered sugar right after they come out of the oven. Let them cool slightly, then roll them again in powdered sugar for that classic snowy finish.
