Prepare the baking tray. Lay foils in such a way that they hang from all 4 sides. This ensures that when taking the brownie out it will be easy and mess free. Press the foils well in the base of the pan and in the corners smoothing it as you do it. Grease the foil well and leave it aside.

Preheat the oven to 325 F.

In a bowl, whisk the flour, baking powder and salt and keep it aside.

Set a sauce pan with about 3 inches of water and heat. Bring the water to a very light simmer. Place another heat proof bowl on top of the simmering sauce pan. Make sure that the base of the second bowl does not touch the water. This is the hot water bath which we will use to melt the chocolate.

Add the chocolate and the butter to the bowl and set it over the simmering water. Stir gently to melt the chocolate until smooth.

Take off the bowl from the heat and slowly add the sugar and whisk.

Now add the eggs one at a time and then whisk well after each addition.

Add the vanilla and whisk.

Add the flour in 3 additions and fold gently with a rubber spatula. The mixture should be smooth and mixed well.

Transfer the batter into the prepared tray. Make sure that the batter spreads to the corners of the baking tray.

Bake in the preheated 325 F oven for about 30 – 35 minutes. Rotate the pan once in between baking. Check with the tooth pick. The tooth pick should come out with few moist crumbs attached to it.

Let the brownies cool in the pan (set over a rack) until they come to room temperature. Then take the brownies out holding the foil. Cut them into desired size pieces and serve.

These Classic Brownies can be stored in room temperature for up to 3 days.
