Preheat the oven to 350°F and line a baking sheet with parchment. No sticky messes allowed.
Whisk together flour, cocoa powder, baking powder, and salt in a bowl. Keep it smooth.
Beat melted butter, brown sugar, and granulated sugar in a separate bowl until fully combined. No shortcuts.
Add eggs, vanilla extract, and espresso powder, then mix until smooth. Commitment is key.
Stir in the melted dark chocolate until the batter reaches peak decadence. Try not to taste-test too much.
Fold in the dry ingredients slowly. Overmixing leads to sadness.
Toss in chocolate chips, stirring just enough to distribute them evenly.
Scoop tablespoon-sized portions onto the prepared baking sheet, leaving 2 inches of space.
Bake for 10 minutes until the edges are set but the centers look slightly soft. Trust the gooey process.
Cool on the baking sheet for 5 minutes, then transfer to a rack. Or just eat one immediately.
Devour with coffee, milk, or straight from the tray. No wrong choices here.
