Some highly rated brownie recipes are AllRecipes.com's Best Brownies and Food Network's Outrageous Brownies. Both recipes use similar ingredients, but the Food Network recipe calls for instant coffee granules and chopped walnuts in the brownies, and the AllRecipes.com recipe has a chocolate frosting recipe for topping the brownies.
To make AllRecipes.com's Best Brownies, melt 1/2 cup butter, then add 1 cup sugar, 2 eggs and 1 teaspoon vanilla. Mix in 1/3 cup cocoa powder, 1/2 cup flour, 1/4 teaspoon salt and 1/4 teaspoon baking powder. Add the batter to a greased and floured 8-by-8-inch baking pan, and bake the brownies for 25 to 30 minutes at 350 degrees Fahrenheit. Frost the brownies with the chocolate frosting recipe made from cocoa powder, honey, vanilla, confectioner's sugar and butter.

Mix well, then pour the batter into a greased and floured 8-inch square pan. Bake for 45 minutes at 300 F. The brownies are done when a toothpick inserted into the center comes out clean. Cool completely before cutting.
