Method
Preparation & Preheating
- Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper and set aside.
- Spoon powdered sugar into a shallow bowl for rolling later.
Mix Wet Ingredients
- In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth and slightly glossy.
- Whisk in the eggs, one at a time, then add the milk (if using), red food coloring, and vanilla until fully combined.
Add Dry Ingredients
- In a separate bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt.
- Gradually fold the dry ingredients into the wet mixture until just combined. Add the vinegar and stir quickly.
Chill the Dough
- Cover the dough and chill for at least 30 minutes.
Shape and Roll
- Scoop 1.5 tbsp to 2 tbsp portions (about golf ball size).
- Roll each portion into a smooth ball, then roll generously in powdered sugar until well coated.
Bake
- Place balls 2 inches apart on prepared baking sheets.
- Bake for 10 to 12 minutes until the edges are set and the tops show glossy cracks.
- Remove from oven and let cookies cool on the sheet for 5 minutes, then transfer to a wire rack to cool completely.
Notes
Dough can be frozen for up to 3 months. To avoid overbaking, pull cookies when the center looks just set; they will finish as they cool.
