Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a medium bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt. Set aside.

In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.

Beat in the egg, instant coffee granules, and vanilla extract until well combined and smooth.

Gradually add the dry ingredient mixture to the wet mixture, stirring until just combined. Do not overmix.

Using a cookie scoop or a tablespoon, drop rounded balls of dough onto the prepared baking sheet, leaving space in between for spreading.

Bake in the preheated oven for about 10-12 minutes or until the cookies are set and edges are slightly crispy.

Let them cool for a minute on the baking sheet before transferring to a wire rack.

Once cooled, lightly dust the cookies with cocoa powder for an extra touch of decadence.
