Stir the cocoa powder and espresso powder into the melted chocolate and let cool slightly.In a mixing bowl using an electric mixer, beat the butter, salt (if using) and both sugars until creamy. With mixer on medium, add eggs 1 tablespoon at a time until incorporated, then beat for 1 minute. Beat in vanilla and melted chocolate mixture, scraping sides of bowl often. When chocolate is incorporated, stir in the flour. Make sure the dough is completely cool, then stir in the remaining 2/3 cup chocolate chips.
