These rich, chewy black cocoa cookies are all about bold chocolate flavor and dramatic looks. Made with black cocoa powder and studded with chocolate chips, they’re like a brownie and an Oreo had a delicious cookie baby.
Whisk together the flour, black cocoa, baking soda, and salt. Set aside.
Using an electric mixer on medium speed, beat the butter, sugar, and brown sugar until light and fluffy (about 2–3 minutes). Mix in the egg and vanilla until combined.
With the mixer on low speed, gradually mix in the dry ingredients just until no dry streaks remain. Stir in the chocolate chips.
Scoop the dough into balls (about 1.5 tablespoons each, a #40 scoop), then chill for 1 hour to help control spread.
Preheat the oven to 350°F (175°C). Line baking sheets with parchment paper or silicone liners.
Place the chilled dough balls on the prepared baking sheets, leaving ample room for spreading. Bake (one pan at a time) 9–11 minutes, or until the edges are set but the centers look slightly soft. Keep the remaining dough chilled between baking batches.
If you like, top each warm cookie with a few more chocolate chips and a pinch of flaky salt.
Let the cookies cool on the pan for 5 minutes, then transfer to a wire rack to cool completely.
Notes
Black cocoa powder: This ultra-Dutched cocoa creates the deep color and flavor in these cookies. King Arthur’s black cocoa is my go-to, but other brands like The Cocoa Trader and Guittard should work well, too.
Chilling the dough: For best results, keep the dough chilled between batches to reduce spreading.
Shaping tip: The cookies may spread unevenly in the oven. Use a round cookie cutter or spoon to gently reshape them right after baking.
Finishing touches: For bakery-style presentation, press a few extra chocolate chips into the tops of the cookies after baking. A sprinkle of flaky salt adds a nice flavor contrast.
Storage: Keep cookies in an airtight container at room temperature up to 4 days.
