Frosted Brownies

Makes 16 brownies

These brownies are moist and packed with chocolate flavor, but they won't crumble when you cut them. In fact, they hold up well enough to pack in a child's lunchbox or bring to a picnic or bake sale. They're pretty good at home, too, with a tall glass of milk. Semisweet chips are fine for this frosting. If you're anxious to firm up the frosting, pop the tray of frosted brownies into the refrigerator for 15 minutes.
3 ounces unsweetened chocolate , chopped
8 tablespoons unsalted butter (1 stick) , cut into chunks
1 cup sugar
1/2 teaspoon baking powder
1/4 teaspoon table salt
2 large eggs
1 teaspoon vanilla extract
2/3 cup all-purpose flour

For the Frosting
4 ounces semisweet or bittersweet chocolate , chopped
1 tablespoon vegetable oil

2. Melt chocolate and butter in small bowl in microwave or in heatproof bowl set over pan of simmering water, stirring occasionally to combine. Cool mixture for several minutes.

3. Whisk sugar, baking powder, salt, eggs, and vanilla together in medium bowl until combined, about 15 seconds. Whisk in chocolate mixture until smooth. Stir in flour until no streaks of flour remain. Scrape batter evenly into prepared pan.

5. Heat chocolate and oil in microwave or in bowl set over pan of simmering water, stirring occasionally until chocolate has melted and mixture is smooth. Cool until barely warm, about 5 minutes. Pour chocolate mixture over brownies and spread evenly with spatula. Continue cooling brownies until glaze sets, 1 to 2 hours.

6. Using foil, lift brownies from pan to cutting board. Slide foil out from under brownies and cut brownies into 2-inch squares. (Brownies can be stored in airtight container for several days.)
