Use a high-powered blender or food processor for the smoothest texture. Roasting hazelnuts is key for flavor and easier skin removal. For a thinner spread, add more coconut oil. Powdered sugar avoids gritty texture. Adjust sweetness as desired. Chill the jar before use for a firmer spread. You can substitute coconut oil with neutral oils, and powdered sugar with powdered sugar alternatives for lower sugar options. Add chopped toasted hazelnuts for a chunky texture. This recipe is naturally dairy-free and suitable for vegans.
