Buttermilk Brownie

I wanted to bake a quick cake and found this recipe in one of my books..buttermilk brownie - with easy mixing (just use a whisk will do) and bake time only 25mins. Best of all i have a tub of ganache sitting in my fridge anyway....
Initially, i was skeptical of the recipe, but in the end it turned out really very very moist and delicious! Everyone in my family loves it..esp. delicious when you eat it still hot..it's more of a crumbly cake texture (not so much of the dense brownie type) without any nuts which i like..:P

So, here's the recipe:-

Buttermilk Brownies
(taken from The Ultimate Cookie Book)
prep: 30mins bake: 25mins oven: 350F makes: 24 brownies

Ingredients:-
2 cups of all-purpose flour
2 cups of granulated sugar (i think it is too much....i reduced the sugar by approx 100g probably 1/4 cup?)
1 tsp of baking soda
1/4 tsp salt
1 cup butter
1 cup water
1/3 cup unsweetened cocoa powder
2 eggs
1/2 cup buttermilk
1-1/2 tsp vanilla ess
1 recipe chocolate-buttermilk ganache (i used normal chocolate ganache)

1) Preheat oven to 350F. Greased a 15x10x1-in or a 13x9x2-in baking pan, set aside. In a medium bowl stir together flour, sugar baking soda, and salt, set aside.
2) In a medium saucepan combine butter, the water & cocoa powder. Bring just to boiling, stirring constantly. Remove from heat. Add the cocoa mixture to the flour mixture. Beat with an electric mixture (i just use a hand whisk) on medium speed until combined. Add the eggs, buttermilk and vanilla. Beat for 1 min (batter will be thin). Pour batter into the prepared pan.
3) Bake abt 25mins for the 15x10x1 inch pan, 35 mins for the 13x9x2 inch pan, or until a wooden toothpick inserted in the center comes out clean.
4) Pour warm Chocolate Buttermilk frosting over the warm brownies, spreading evenly. Cool in pan on a wire rack. Cut into 24 bars.
