In a medium bowl, whisk together flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
1 1/2 cups all-purpose flour, 1/4 cup unsweetened cocoa powder, 1 teaspoon baking powder, 1/2 teaspoon baking soda, 1/4 teaspoon salt
In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
1/2 cup unsalted butter, softened, 3/4 cup granulated sugar, 1/4 cup packed brown sugar
Beat in the egg and vanilla extract. Then, add red food coloring and white vinegar. Mix well.
1 large egg, 1 teaspoon vanilla extract, 1 tablespoon red food coloring, 1 teaspoon white vinegar
Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined. Do not overmix.

Cover the dough and chill in the refrigerator for at least 2 hours (or preferably overnight). This will prevent the dough from spreading too much while baking.
Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
Roll the chilled dough into 1-inch balls. Roll each ball in powdered sugar, ensuring it's fully coated.
1/2 cup powdered sugar
Place the coated dough balls on the prepared baking sheets, leaving space between each cookie. Bake for 10-12 minutes, or until the edges are set and the tops are slightly cracked.
Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
