In a bowl add curd and baking soda and whisk it well till you see small bubbles.
Add in sugar, oil, milk and whisk it well till everything is well combined.
Lastly add in flour, cocoa powder, baking powder and whisk everything well to achieve a smooth lumpfree batter.
Pour the batter into greased and lined 5.5*3.5 inch rectangular mould.
Set a cooker on low- medium heat and spread a layer of salt in it. Place a small stand in the centre of the cooker and close it with a lid. Let it preheat for 10 mins.
Once preheated, place the mould inside the cooker and cook for 30-35 minutes or until a skewer inserted in the centre comes out clean .
Once the cake is done, place a bar of chocolate on top of it and cover the cooker with a lid again for 5 minutes or till chocolate melts a little.
Once done, demould the cake, pour chocolate milk around the cake and serve.
