In a small skillet over medium heat, add macadamia nuts. Stir continually to toast and brown nuts. Once they are fragrant, remove from skillet and place into food processor.
Pulse a few times to grind the nuts then add the remaining ingredients, except water.
Process until smooth. Taste and adjust salt and sweetener if needed.
Add 2 tablespoons of water and process again. If the mixture is still too thick for your liking, add another tablespoon. Continue to add more if needed to desired consistency. I prefer my texture thick and used just 4 tablespoons of water.
This recipe makes 12 ounces of nut butter. Store covered in the refrigerator for up to 2 weeks.
