Preheat the oven to 350°F and line a baking sheet with parchment paper. Because burnt cookies are a crime.
Whisk together flour, cocoa powder, baking soda, and salt. No clumps allowed.
Cream the butter, brown sugar, and granulated sugar in a separate bowl until light and fluffy. No shortcuts.
Mix in the egg and vanilla extract until fully incorporated. You’re almost there.
Gradually add dry ingredients to the wet mixture, stirring until just combined. Overmixing equals sad cookies.
Fold in chocolate chips because resistance is futile.
Scoop tablespoon-sized portions onto the baking sheet, spacing them 2 inches apart. No cookie collisions.
Bake for 12 minutes until edges are set but centers stay slightly soft. Trust the process.
Cool cookies on the sheet for 5 minutes, then transfer to a rack. Or eat them now—your call.
Dip half of each cooled cookie in melted chocolate, then drizzle strong coffee over the top. Next-level indulgence.
Let them set before devouring, or just eat them messy. No judgment.
