Fudge Iced Brownies

I was going to bake a chocolate cake for a birthday at work last week and was missing an ingredient so I thought I would make brownies instead.  There are probably a thousand different brownie recipes but I went in search of one similar to the ones I used to get when I was a girl growing up in West Texas.  I think I have mentioned before that we had a bakery near our house called Snow White Bakery.  Oh, the smells in that bakery come back to me even after all these years later.  They used to have these iced brownies that were so perfect.  I went to Google Images to see if I could see any pictures of brownies that reminded me of those.  I came across Gotta Make This blog and there was recipe that looked good enough to try.  I got quite a few compliments so I think it's a keeper recipe.

Fudge-Iced Brownies
Brownies:
2 cups brown sugar
1 cup butter, softened
1 cup all-purpose flour
1/2 cup cocoa
4 eggs
2 teaspoons vanilla

Icing:
1/2 cup butter
5 tablespoons cocoa
1/8 teaspoon salt
2 teaspoons vanilla
2 cups powdered sugar
Hot water

To make Brownies: Combine brown sugar, butter, flour, cocoa, eggs and vanilla in a bowl. With electric mixer, beat at medium speed until smooth and creamy. Spread evenly into a buttered 9 x 13  baking pan. Bake at 350F until just set, about 25 minutes. (It will take a bit longer if you are using a glass pan.)  Remove from oven and let cool.

To make Icing: Melt butter in a saucepan; stir in cocoa, salt and vanilla. Heat mixture, stirring frequently, until boiling. Remove from heat and stir in powdered sugar. (Mixture will be thick.) Add small amounts (1 to 2 teaspoons) of hot water at a time and stir until mixture is just thin enough to spread over brownies. Let cool and cut into squares.
