In a mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
Add the egg and mix until well combined.
In a separate bowl, sift together the all-purpose flour, cocoa powder, instant coffee granules, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture and mix until a cookie dough forms.
Stir in the dark chocolate chips.
Cover the dough and refrigerate for at least 30 minutes to firm up.
Preheat your oven to 180°C (350°F) and line a baking sheet with parchment paper.
Scoop out small portions of dough and roll them into 1-inch balls.
Place the dough balls on the prepared baking sheet, spacing them a few inches apart.
Bake in the preheated oven for about 12 minutes or until the edges are set but the centres are still slightly soft.
Allow the cookies to cool on the baking sheet for a few minutes, then transfer them to a wire rack to cool completely.
