Step 1: Prepare the Dough

1. In a medium bowl, whisk together the flour, cocoa powder, baking powder, and salt. Set aside.
2. In a large mixing bowl, beat the butter and granulated sugar until light and fluffy, about 2 minutes.
3. Add the egg, vanilla extract, and red food coloring, mixing until fully incorporated.
4. Gradually add the dry ingredients to the wet mixture, stirring until combined. The dough will be thick and slightly sticky.

Step 2: Chill the Dough

1. Cover the dough with plastic wrap and refrigerate for at least 1 hour. This helps firm up the dough and enhances the flavor.

Step 3: Shape and Coat the Cookies

1. Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. Scoop out tablespoon-sized portions of dough and roll them into balls.
3. Generously coat each dough ball in powdered sugar, ensuring full coverage.

Step 4: Bake to Perfection

1. Place the coated dough balls onto the prepared baking sheet, spacing them about 2 inches apart.
2. Bake for 10–12 minutes, or until the cookies are set but still slightly soft in the center.
3. Remove from the oven and let them cool on the baking sheet for 5 minutes before transferring to a wire rack.
