These taste like a brownie version of a Hershey bar. A chocolate covered cherry lover could add dried cherries for the same effect.
1 stick (1/2 cup) unsalted butter
8 oz fine-quality milk chocolate, chopped
3/4 cup packed light brown sugar
1 teaspoon pure vanilla extract
2 large eggs
3/4 cup all-purpose flour
1 tablespoon unsweetened cocoa powder
1/2 teaspoon salt
1/4 teaspoon baking powder
Put oven rack in middle position and preheat oven to 350°F. Butter and flour a 9-inch square baking pan.
Melt butter and half of chocolate in a 1 1/2-quart heavy saucepan over low heat, stirring, until smooth. Remove from heat and cool to lukewarm. Stir in brown sugar and vanilla. Add eggs 1 at a time, beating well after each addition, until mixture is glossy and smooth.
Whisk together remaining ingredients, then stir into chocolate mixture. Stir in remaining chocolate.
Spread batter in pan and bake until a wooden pick or skewer comes out with a few moist crumbs adhering, 25 to 30 minutes.
Makes 16 brownies.
