Eggless Brownie - "the best I made & tasted"

Hi.. my husband got chocolate for my daughter.. I carefully sneaked into the refrigerator & took one to make a brownie.. I came across this recipe and wanted to try for always... It turned out very well... very tasty as well..
 

 
Ingredients:
 
All-purpose flour - 1 cup
Sugar - 1 cup
Cocoa powder - 1/2 cup
Baking Soda - 1/2 tsp
Chopped nuts - 1/2 cup (almonds/hazelnuts/walnuts/cashew)
Chocolate bar - 1 (I used Dairly Milk - 8 bricks)
Butter (unsalted) - 3 tbsp.
Plain Yogurt - 1/2 cup
Vanilla Essence - 1/2 tsp
Milk - about 1/2 cup or enough to have a creamy batter
 
 
Method:

1. Preheat oven to 180 degrees C. Grease the baking tray
2. Melt chocolate with little milk and Melt butter & whisk them together.
3. Add yogurt, vanilla essence and sugar to chocolate-butter mix and beat till it is creamy (you can add 1 to 2 tbsp. of milk)
4. Sieve flour, cocoa powder & baking soda twice. Add this to yogurt-chocolate mix and beat until you get a smooth & creamy texture (you can add milk if necessary)
5. Add 3/4 of the chopped nuts to the batter
6. Pour the mixed batter into the prepared tin, sprinkle balance 1/4 of the nuts on top and bake at 180 deg C for about 30 – 40 minutes or until a toothpick inserted in the center comes out clean.
7. Remove and cool in the pan for 10 minutes before cutting into equal squares

 Tips:

• Tastes best with vanilla ice cream during summers or hot chocolate/caramel sauce during winners
• It freezes very well and a great snack for the kids for their break time
