Ingredients
Method
- Step 1: In a medium bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt.
- Step 2: In the bowl of a stand mixer fitted with a paddle attachment (or using a hand mixer), cream the butter and sugar together until smooth and fluffy, about 2 minutes.
- Step 3: Add the egg and mix again until smooth. Then add the milk and vanilla, mixing until fully combined.
- Step 4: Gradually add the dry ingredients to the wet mixture and mix until just combined. Do not overmix.
- Step 5: Chill the dough in the refrigerator for at least 2 hours or up to 2 days for best texture.
- Step 6: Preheat the oven to 350°F (175°C) and line 2 baking sheets with parchment paper.
- Step 7: Roll the dough into 1½ tablespoon-sized balls. Dip one side of each dough ball in sparkling sugar and place sugar-side up on the baking sheet, spacing them about 2 inches apart.
- Step 8: Bake for 8–11 minutes, until the tops are puffed and just set. Remove from the oven and let the cookies cool on the baking sheet for 8–10 minutes before transferring to a wire rack.
Notes
For extra chocolate flavor, use dark cocoa powder. The dough can be frozen for up to 3 months — just roll into balls before freezing and bake directly from frozen, adding 1–2 minutes to the bake time.
