melt a stick of butter on a skillet. put 1/4 tsp salt on top of the butter. once the butter has melted, mix in a cup of sugar and mix on med-high until the sugar is fully dissolved into the butter, turn the heat to low. mix in 1/3 cup of chocolate. real chocolate is better but you can use powdered cocoa. once it's a consistent mix, turn the heat off. add 1tbsp vanilla, crushed walnuts, half a cup of flour, mix well for a couple minutes while it cools down then add two eggs and a 1/4 tsp of baking powder. did i mention you should mix it well? butter up your 9x9 baking pan and then throw some flour on top of the butter before you pour in your mix. you can throw some extra pieces of hard chocolate on top once its evenly spread out. bake at 350 for 20-25 minutes or until people start asking when those brownies are going to be ready
you can put chocolate frosting on top too. if you do it when they are hot the frosting melts and creates an even coat and even melts down into the brownies a little bit
