Mix cocoa powder, milk and the condensed milk at first. Mix it well so that it's lumpfree. Now keep the saucepan on a low heat. Add butter to it and keep stirring. This mix is to be used in the biscuit crumbs.
Stir until it thickens a bit and becomes glossy. Take it off the heat. Reserve some of this for the ganache to be spread on top of the brownies.
Add this cocoa mix to the biscuit crumbs and also the nuts. Give it a good mix and spread it in a wide greased dish. Top it up with the ganache and the nuts.
Set in the fridge for an hour, well covered. After an hour, cut into desired shapes and serve chilled. Instant chocolaty brownies are ready to serve to your families. Enjoy!
