These luxurious brownies combine unsweetened chocolate, bittersweet chocolate, chocolate chips, and cocoa powder. The dark batter is intense and saturated with flavor.
|Butter (for the pan)|
|Flour (for the pan)|
|7||ounces unsweetened chocolate, chopped|
|3||ounces bittersweet chocolate, chopped|
|5||tablespoons unsweetened cocoa powder|
|½||teaspoon baking powder|
|1¼||cups miniature semisweet chocolate chips|
|1½||cups (3 sticks) unsalted butter, at room temperature|
|2¾||cups granulated sugar|
|2||teaspoons vanilla extract|
|Confectioners’ sugar (for sprinkling)|
1. Set the oven at 350 degrees. Butter a 9- by 13-inch baking pan. Dust the pan with flour, tapping out the excess.
2. In a bowl over hot but not boiling water, melt the unsweetened and bittersweet chocolates. Remove the bowl from the water and wipe the bottom dry; cool.
3. In another bowl, whisk the flour, cocoa powder, cornstarch, baking powder, and salt to blend them.
4. In a smaller bowl, toss the chocolate chips with 2 teaspoons of the flour mixture.
5. In an electric mixer at medium speed, cream the butter for 2 minutes. Add the granulated sugar in 3 additions, beating for 1 minute after each. Beat in the eggs, one at a time, blending well after each addition. Blend in the vanilla. With the mixer set on its lowest speed, add the melted chocolate mixture, then the flour mixture, beating only until blended.
5. Remove the bowl from the mixer stand. With a large metal spoon, stir in the chips. Transfer the batter to the baking pan, spreading it evenly and smoothing the top.
6. Bake the brownies for 45 minutes, or until just set. Transfer the pan to a wire rack to cool completely.
7. Make 5 horizontal cuts and 3 vertical cuts to form 24 large rectangles. Or make 7 horizontal cuts and 5 vertical cuts to form 48 bars. If you like, cut each of the smaller brownies in half to make 96 minis. Use a small offset spatula to remove the brownies from the pan. Store in an airtight container. Just before serving, dust with confectioners’ sugar.
