Preheat the oven to 400 °F/204 °C. In a large baking sheet, spread the hazelnuts and macadamia nuts. Bake for about 8-10 minutes, until they are lightly browned. Remove the nuts from the oven and allow to cool for about 15 minutes.
Once the nuts are cooled, rub them together in your hands to loosen and remove their skins.
In a food processor or high powdered blender, add the nuts and process until you get a nice creamy texture.
Add remaining ingredients and process again until smooth and all the ingredients are combined.
Pour into a jar and enjoy
Notes
You can buy roasted hazelnuts and macadamia nuts to save time on toasting them.
It'll take time for the nuts to break down in the food processor, if the motor is getting too hot, give it a break.
Scrape down the food processor between the breaks.
