Preheat the oven to 325°F and line a baking sheet with parchment paper. No one likes stuck cookies.
Beat butter and powdered sugar in a bowl until light and creamy. No lazy mixing.
Whisk together flour, cocoa powder, espresso powder, and salt in another bowl. No lumps allowed.
Combine the dry ingredients with the butter mixture, mixing until it forms a dough. Don’t overwork it.
Fold in the chopped chocolate for extra decadence. Because more chocolate is always the right choice.
Roll the dough into a ½-inch thick rectangle and cut into desired shapes. Circles? Squares? Chaos? Your call.
Place cookies on the baking sheet and chill for 10 minutes. This prevents sad, spreading cookies.
Bake for 12 minutes, or until edges look set. Try not to eat them straight from the oven.
Cool completely before dipping or drizzling with melted chocolate. Or skip this step if patience isn’t your thing.
Devour with coffee, milk, or straight from the tray. No regrets.
