First blend the baked hazelnuts in blender, then put them aside in some bowl

Then add the dates, cocoa powder and water in the blender and blend till u get paste

In the end add the hazelnuts to the date paste in the blender and blend till u get homogene paste and you are done!

Store in a glass jar in fridge

You can also make this without the nuts, but you will have to add less water (sip the water while blending as needed)
