Preheat the oven to 375°F
Put the hazelnuts in one layer on a tray and roast for about 15 minutes.
Allow the nuts to cool down and peal by rubbing them between your hands.
Mix the peeled nuts until you have a smooth, shiny smear. This may take a while, so be patient.
Add cocoa, coconut oil, 1 tablespoon agave syrup, vanilla powder and a pinch of salt. Mix the ingredients.
Add rapeseed oil until you reach the desired consistency. Taste and add more agave syrup if you want a sweeter result. I usually use about 5 tablespoons.
Pour into a jar and store in the fridge or serve at once.
