Melt chocolate chips, butter and cocoa together in microwave (Nuke for 30 seconds at a time, stirring between each session, until smooth. Don’t overnuke.)
Beat eggs briefly, add sugar, vanilla and coffee, Mix until thoroughly combined.
Fold in chocolate, then fold in flour and baking powder, and stir until the baking powder is thoroughly incorporated and no lumps remain (because nothing is grosser than a lump of baking powder in your cookie).
Chill about 10 minutes in the refrigerator. Drop by tablespoons on parchment-covered cookie sheets, bake at 375 for 8-10 minutes, cool on the pan.
