Soak dates in lukewarm water overnight.

Drain the water from the dates, rinse them and put in a blender.

Add ground hazelnuts, cocoa powder and coconut oil to the blender and blend to get a dough.

At the end, add the chopped hazelnuts and stir them into the mixture.

Sprinkle the baking paper with ground hazelnuts and shape the dough into a square and let it rest in the refrigerator for at least an hour to harden.

Then cut into 12 slices.
