Take the baking powder, flour, sodium bi-carbonate and a small pinch of salt and sift them

After that is done, keep it aside

Now take a pan and boil a cup of water

Take a bowl and fill the grated chocolate

Make it sit on the pan and ensure that it doesn't get drowned

Take another bowl and add castor sugar and butter

Stir them till the mixture gets creamy

Now add the melted chocolate and mix them

This should be added with butter milk or beaten curd 

Add the flour to the mixture and mix well

Take a glass bowl and grease it with butter 

Now pour the flour mixture and microwave it for three minutes

Remove the mix and microwave it again at 70 per cent heat for another minute

Set this aside for five minutes

The microwave plus grill mode must be pre-heated for five minutes at 220 degree Celsius and the brownies must be baked at 220 degree Celsius for three minutes

This can be removed from the microwave and allowed to cool
