- 1 3/4 cups flour
- 1/2 cup natural cocoa powder

- 1 cup unsalted butter, room temp
- 1 3/4 cups sugar, plus ore for rolling

To make cookies: adjust oven rack to middle position and preheat to 350. Line two baking sheets with parchment paper.
In a medium bowl, combine flour, cocoa powder, baking soda, and salt. In the bowl of a stand mixer fitted with a paddle, beat butter on medium until smooth. Add the sugar and beat on medium until light and fluffy, 2 to 3 minutes. Add the egg and vanilla and beat on medium until combined. Add the flour mixture and beat on low until just combined.
Form the cookies into 3 ounce balls and roll in remaining sugar. Bake 6 cookies at a time, 11-14 minutes, until edges have set and the centers are puffed and starting to crackle. Cool on the pan on a cooling rack.
