Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a large mixing bowl, cream together 1 cup of unsalted butter and 1/2 cup of powdered sugar until light and fluffy. Add 1 teaspoon of vanilla extract and mix well.

In a separate bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of ground cinnamon, and 1/4 teaspoon of salt. Gradually add this to the wet mixture, stirring until dough forms.

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

Bake for 10-12 minutes until edges are light golden brown and centers are soft. Keep an eye on them.

Allow cookies to cool for about 5 minutes, then roll in a mixture of 1/2 cup of powdered sugar and 1 teaspoon of ground cinnamon.
