Cook's Note

Brownies may be refrigerated, wrapped in plastic, up to 1 week.


  1. Step 1

    Preheat oven to 325 degrees. Butter a 13-by-9-inch baking dish; line with parchment paper, allowing a 2-inch overhang. Butter lining, excluding overhang; set aside. Put butter, unsweetened chocolate, and 1 ounce semisweet chocolate into a heatproof bowl set over pan of simmering water; stir until butter and chocolates have melted. Remove from heat.

  2. Step 2

    Whisk together flour and salt in a small bowl; set aside. Put sugar and espresso powder into the bowl of an electric mixer fitted with the paddle attachment; mix on low speed until combined. Raise speed to medium. Add chocolate mixture; mix until combined. Mix in eggs, one at a time, and vanilla. Add flour mixture; mix until just combined. Fold in remaining 6 ounces semisweet chocolate.

  3. Step 3

    Pour batter into prepared dish; smooth top with an offset spatula. Bake until a cake tester inserted into center comes out with a few moist crumbs attached, 1 hour to 1 hour 10 minutes. Transfer dish to a wire rack; let cool 40 minutes. Lift out brownie by overhang. Return to rack; let cool completely. Cut into forty-five 1 1/2-inch squares.

    These are outstanding. I got lots of compliments when I brought them to a party. They're rich, moist, and intensely chocolately -- their density is akin to flourless chocolate cake -- and the coffee makes them perfect for people who love mocha-flavored desserts. If you can't find instant espresso powder, you can substitute freshly-ground beans, to great effect. You can also substitute instant coffee, such as Folger's, although the mocha flavor won't pack quite the same punch.
