Well, Nutella is not a low calorie food but if you compare homemade Nutella with store-bought Nutella, homemade is healthier in the sense that you know exactly what goes into it and you can control the ingredients. To make Nutella healthier, use organic hazelnuts, coconut oil, high quality organic chocolate (you can us dark chocolate if you prefer), organic cocoa powder, and lower the amount of powdered sugar.
