Add 1/4 cup water to a small sauce pan. Add butter, chopped chocolate and tir slowly on lowest flame. In the meanwhile heat oven at 180C. Grease and line a 10inch square tin.

Once the chocolate has completely melted and smooth let cool for 5 minutes.

Now add condensed milk and mix well.

Sieve wheat flour and baking powder together over the wet ingredients. Mix well. Add 1/2 cup chopped walnuts and mix well.

Pour the brownie batter into the lined tin and tap gently. Sprinkle the remaining 1/4 cup chopped walnuts all over.

Bake in the preheated oven for 30-30 minutes. The top will turn crispy and crack here and there. Once a tester comes out clean in multiple places, remove from oven and let cool. Cool for 20 minutes before slicing. Serve brownies warm.
