1: Prepare the Dough

1. Combine the flour, cocoa powder, and salt in a medium bowl, then set it aside.
2. In a separate large mixing bowl, cream the butter and powdered sugar together until the mixture becomes light and fluffy.
3. Mix in the vanilla extract until well incorporated.
4. Gradually add the dry ingredients to the butter mixture, stirring until just combined.
5. Fold in the mini chocolate chips or finely chopped chocolate for extra bursts of chocolate flavor.

2: Chill the Dough

1. Cover the dough with plastic wrap and place it in the refrigerator for 30-60 minutes until it becomes firm and easy to handle.

3: Shape and Bake

1. Preheat your oven to 350°F (175°C) and prepare a baking sheet by lining it with parchment paper.
2. Roll the chilled dough into 1-inch balls and arrange them on the baking sheet, leaving about an inch of space between each cookie.
3. Bake for 10-12 minutes, ensuring the cookies are set but not browned.
4. Allow the cookies to rest on the baking sheet for 5 minutes, then move them to a wire rack to cool fully.

4: Coat the Cookies

1. Once the cookies have cooled completely, roll them in powdered sugar until fully coated.
2. For a festive, snowy appearance, roll the cookies in powdered sugar a second time just before serving.
