Preheat oven to 375°F. Line cookie sheet with parchment paper.
Mix softened butter, 1/2 cup powdered sugar, and vanilla with an electric mixer until fluffy.
Mix dry ingredients in a separate bowl: flour & salt. Slowly, add the flour mixture to the butter/sugar until the dough comes together. Fold in the mini chocolate chips.
TIP // If the dough is too soft or sticky, chill it until you can work it easily with your hands (30 minutes or so).
Using a cookie scoop or spoon, scoop small amounts of dough (approx. 1-2 tablespoons worth) and roll into balls using the palms of your hands. Place balls of dough on prepared cookie sheets.
Bake cookies for 7-9 minutes until bottoms are just slightly brown. Remove from oven and cool for a few minutes, until you can handle them.
Fill a small bowl with sifted powdered sugar and roll each cookie in the sugar until coated. Place on a rack to cool. (Once cookies are cooled, or just before serving, you can re-roll them in more powdered sugar to look like they're freshly covered in "snow"). Enjoy!
