KING ARTHUR FLOUR: THE BEST FUDGE BROWNIE EVER

Steps:

• Preheat oven to 350 degrees.
• Lightly grease a 9x13 pan.
• In a medium sized microwave-safe bowl or in a saucepan, melt the butter on low heat, then add the sugar and stir to combine.
• Return the mixture to the heat or microwave briefly, just until it's hot but not bubbling. It will become shiny looking as you stir it. Heating the buter and sugar a second time will dissolve more of the sugar, which will yield a shiny top crust on your brownies.
• Transfer the mix to a mixing bowl.
• Stir in the cocoa, salt, baking powder, and vanilla.
• Add the eggs, beating till smooth; then add teh flour and chips and nuts if using. Beat until well combined.
• Spoon the batter into the prepared pan.
• Bake the brownies for 28-30 minutes, until a cake tester inserted in the center comes out clean or with just a few crumbs clinging to it.
• The brownies should feel set both around the edges and in the center.
• Remove from the oven, and after 5 minutes loosen the edges with a table knife, this will help preven the brownies from sinking in the center as they cool.
• Cool completely before cutting and serving.
