1. Preheat oven to 350 degrees. Melt butter over medium low heat in a saucepan. Stir in sugar, cocoa and eggs. Add flour and salt and stir until smooth.
2. Pour into lightly buttered 8 inch square baking pan. Drop peanut butter by teaspoonfuls onto batter. With a table knife, gently stir batter to create swirls.
3. Bake 30 minutes or just until brownies begin to pull away from sides of pan and wooden pick inserted near center comes out clean. Do not overbake. Remove from oven and place pan on wire rack to cool completely.
4. For glaze, combine confectioners' sugar and peanut butter. Stir in milk, 1 tablespoon at a time to reach spreading consistency. Spread evenly over brownies. Sprinkle with peanuts. Cut into bars before serving. Makes 16 brownies.
