-
Preheat oven to 350°F.
-
Bring the water to a low boil; add the butter and the 4 tbsp of cocoa.
-
In a mixing bowl combine the brownie dry ingredients and the sugar.
-
Slowly mix in the water/butter/cocoa mixture.
-
Whisk the egg and buttermilk together, and quickly add to the batter.
-
Mix until combined, making sure to scrape the sides and bottom of the bowl.
-
Grease and dust with cocoa a half sheet pan (restaurant supply style), or line with parchment paper.
-
Pour batter into the pan and tap the edge of the pan to settle the batter out.
-
Bake for about 20 min or until brownies test done.
-
You may need to turn the pan once half way through to even out the cooking, depending on your oven. I do just out of habit.
-
To make frosting, combine all the frosting ingredients in a mixing bowl and mix until smooth and creamy.
-
Put frosting in the fridge until you are ready to frost. It is easier to frost if it is a little cool.
-
Bring it out of the fridge and let it come up to almost room temperature (Should be spreadable, but soft like room temperature butter).
-
Remove brownies from the oven and allow them to cool completely before frosting.
-
Cut with a clean knife and enjoy.

To make a cake, doubling the recipe yields enough batter to fill 2 9-inch round cake pans. I highly recommend using parchment on the bottom and greasing the side to get the best results when you try to remove the cake from the pan.
