1. Put the dates, the nuts, the vanilla extract, the water and the salt into a blender and process until well combined.

2. Add the cocoa and process some more. Don’t add any more water even it seems too thick because this will give you the right texture.

3. Line a smaller pan (a plastic box will also do) with parchment paper, tip the mixture in and spread it out evenly so that your “dough” is at the same height everywhere.

4. Process the ingredients of the chocolate frosting in a blender, pour it on top of the brownies and put them in the fridge for a couple of hours.
