Ingredients
Method
Preparation
- In a large bowl, beat the butter, granulated sugar, and brown sugar together on medium-high speed until fluffy and light in color, about 2-3 minutes.
- Add the egg and vanilla extract, then beat on high speed until combined, scraping down the sides as needed.
- In a separate bowl, whisk the flour, cocoa powder, baking soda, and salt until combined.
- With the mixer running on low speed, slowly pour the dry ingredients into the wet ingredients and mix until combined.
- Finally, beat in the chocolate chips. The dough will be thick and sticky.
Chilling
- Cover the dough tightly and chill in the refrigerator for at least 3 hours, up to 3 days.
Baking
- Preheat the oven to 350°F (177°C) and line baking sheets with parchment paper.
- Scoop and roll the dough into balls (about 1.5 tablespoons each).
- Roll each ball in granulated sugar, then generously in confectioners' sugar. Place 3 inches apart on baking sheets.
- Bake cookies for 11-12 minutes, until edges are set but centers still look soft. If they aren't spreading by minute 9, remove from oven and bang the baking sheet on the counter 2-3 times.
- Cool cookies for 5 minutes on the baking sheet, then transfer them to a cooling rack.
Notes
Store leftover cookies in an airtight container for freshness. They can also be frozen for up to 3 months.
