3 (1-ounce) squares unsweetened baking chocolate
3/4 cup sugar
1/4 cup milk
1 tablespoon light corn syrup
1 teaspoon vanilla
1/2 cup all-purpose flour
1/2 teaspoon baking powder
To melt chocolate on stove-top, place chocolate in 1-quart saucepan. Cook over low heat, stirring constantly, until chocolate is melted and smooth (1 to 2 minutes). Remove from heat; cool slightly.
To substitute unsweetened cocoa for unsweetened baking chocolate, use 3 tablespoons unsweetened cocoa plus 1 tablespoon butter for each ounce of unsweetened baking chocolate.
Reduce baking temperature by 25°F if using dark or nonstick baking pan.
To prepare brownies in 13x9-inch baking pan, double all ingredients. Bake for 30 to 35 minutes or until toothpick inserted in center comes out clean.
