BROWNIES WITH A CHOCOLATE GLAZE AND MINT FROSTING

Steps:

• Put oven rack in middle of oven; set to 325°F.
• Construct a foil sling: Cut one 18" length foil and fold it lengthwise so that it is 8-inches wide.
• Fit foil into length of 9x13-inch baking dish, pushing it into corners and up sides of pan; allow excess to overhang pan edges.
• Cut one 14-inch length foil and, if using extra-wide foil, fold it lengthwise so that it is 12" wide; fit into width of baking pan in same manner, perpendicular to first sheet.
• Spray foil-lined pan with nonstick cooking spray.
• Whisk together flour, salt, and baking powder in medium bowl; set aside.
• Melt chocolate and butter in large heatproof bowl set over saucepan of almost-simmering water, stirring occasionally, until smooth.
• (Alternatively, in microwave, heat butter and chocolate in large microwave-safe bowl on high for 45 seconds, then stir and heat an additional 30 seconds. Stir again, and, if necessary, repeat in 15-second increments; do not let chocolate burn.) When chocolate mixture is completely smooth, remove bowl from saucepan and gradually whisk in sugar.
• Add eggs, one at time, whisking until thoroughly combined after each addition.
• Whisk in vanilla.
• Add about one third of flour mixture and fold with rubber spatula until almost fully incorporated; repeat with half of remaining flour, then all of remaining flour, folding until batter is completely smooth and homogeneous.
• Transfer batter to prepared baking pan; using spatula, spread batter into corners of pan and smooth surface.
• Bake until toothpick or wooden skewer inserted into center of brownies comes out with few moist crumbs attached, 30 to 35 minutes.
• Cool on wire rack to room temperature, about 2 hours.
• For the frosting: In standing mixer fitted with flat beater, beat butter and confectioners' sugar at low speed until just incorporated, then increase speed to medium and beat until smooth and fluffy, about 1 1/2 minutes.
• Add 1 tablespoon milk and mint extract and continue to beat until combined, about 30 seconds, adding up to 1 additional tablespoon milk if necessary to achieve soft, spreadable consistency.
• Using offset spatula, spread mint frosting evenly onto cooled brownies, cover with foil, and refrigerate until firm, about 1 hour.
• For the glaze: Melt chocolate and butter in medium heatproof bowl set over saucepan of barely simmering water, stirring occasionally, until smooth; set aside to cool slightly, about 10 minutes.
• Pour chocolate glaze on frosted brownies; using offset spatula, spread glaze into even layer.
• Cover with foil and refrigerate until firm, about 1 hour; remove brownies from pan by lifting foil overhang; cut into 2-inch squares and serve.
• (Store leftovers in airtight container in refrigerator).
