Chocolate-Apple Brownies with Dulce de Leche Frosting
Preheat oven to 350 degrees F. Lightly grease a 13x9x2-inch baking pan; set aside.
In a large bowl combine sugar, melted chocolate, butter, baking soda, and salt. Beat with an electric mixer on medium speed until smooth. Beat in eggs and vanilla. Beat in flour just until combined. Stir in apples. Pour batter into the prepared pan, spreading evenly.
Bake about 20 minutes or until center is set and edges start to pull away from sides of pan. Cool in pan on a wire rack about 20 minutes or until slightly warm.
Immediately pour Dulce de Leche Frosting over brownies, spreading evenly. Sprinkle with nuts. Cool completely on rack. Cut into bars.
