Cocoa brownies

This recipe is from Joy of Baking.com!
These brownies are pure chocolate squares with very little flour used!

Ingredients:
Butter ( salted ) - 10 tbsp or 140 gms,
White granulated sugar- 1 and 1/4 ( 250 gms ),
Unsweetened cocoa pwd- 3/4 cup or 75 gms,
Vanila essence- 1tsp,
Eggs-2,
All purpose flour- 1/2 cup or 65 gms,
Baking soda - 1/4 tsp,
Yogurt - 2 tbsp,
Light cream- 2 tbsp 
( I have filled 1/4 measuring cup with 2 tbsp of yogurt and 2 tbsp of cream )
If sour cream is available use 1/4 cup instead of yogurt and cream.
Semi sweet chocolate chips- 1/2 cup or 85 gms.

Method:
Take a 8 inch square pan and line it with aluminium foil and it should be hanging 2 inches over the sides so that you can lift the brownies from the pan.

Grease the sides of the foil and  the bottom with butter.
Pre heat oven to 325 F or 165 C
Microwave the butter in a cup or medium size bowl for a minute to melt it.

Pour the melted butter in a bowl.

Stir in the sugar ( I always grind my sugar since they are big crystals).

Stir with a wire whisk for few seconds.

Add the sifted cocoa powder.

Mix and then add the vanilla essence.

Add the eggs one at a time and beat till the batter is nice and shinny ( 30 to 40 second )

In another bowl sift the flour and baking soda.
Remove the wire whisk and  lightly fold in the flour mixture to the cocoa batter.

Once the flour is mixed,pour the yogurt cream mixture and the chocolate chips.

 Mix and the pour the batter into the pan.

With a knife smooth the top.

Give a light tap and bake for 30 minutes or a tooth pick inserted in the center,comes out with moist crumbs.
If you over bake it ,the brownies will be hard.
Start checking a few minutes before the full baking time.

Take out from oven and leave it to cool to room temperature.

 Cover and put in the fridge to set for 2 hours.

Lift the foil from the pan.

Place it on a cutting board and remove the sides and then with a knife cut into 16 squares.

Enjoy and keep the rest in the fridge.
