Soak the raw hazelnuts for about 7 hours or overnight and drain them. Dry the nuts and throw them in a food processor. Pulse the nuts a couple of times and then add the dates and cacao powder. Process until everything comes together. Place everything on a piece of parchment paper and press it into a rectangle shape. You can top them with some crushed hazelnuts (optional).

Now place the bar in the freezer until it sets and you can cut it into little bars. Enjoy!
