Preheat oven to 180°C/360°F and put all hazelnuts in the oven to roast for 8 min.
Chop milk chocolate into pieces.
All you need is a towel and your hands. And follow the video :)
Grind the hazelnuts until they form a paste. (i know it takes a long)
Add to the nut-paste oil, cocoa powder, sugar powder, salt and vanilla extract. Combine them until smooth.
Melt chocolate and add to the mixture. And again mix all together.
The end is near. Pour in a jar and let it cool. If you like it firm, put it in the fridge.
