Preheat the oven to 350°F/175°C. Line 2 baking sheets with parchment paper.
In a small bowl, whisk together flour, baking soda, salt, espresso powder and cocoa powder. Set aside.
In a mixer bowl fitted with the paddle attachment, beat butter, granulated sugar and brown sugar on medium speed about 3 minutes, until light and fluffy. Add in egg and vanilla extract, beat until combined. Scrape down the sides as needed. On a low speed add the flour mixture to the wet mixture and beat just until combined. Do not over mix.
Make the coating: In a small bowl, toss together sugar and espresso powder.
Use a cookie scoop to scoop the dough out, roll them in the cinnamon-sugar mixture, and place on the prepared baking sheet, preferably 6-8 cookie dough per sheet as they will spread. Bake for about 10-12 minutes, until cookies begin to puff up and crack on the outside. Allow cookies to cool on the baking sheets for 10 minutes then gently transfer to a wire rack to cool completely.
Store cookies in an airtight container for up to 3 days. The leftovers can be frozen for up to 2 months.
