Add the hazelnuts to a toaster oven baking sheet. Toast for 5 minutes, until nuts are golden brown. No toaster oven? Roast at 375º for 10 minutes, stirring every 3 minutes.

Once browned, transfer the hazelnuts into a food processor. Process on high until the nuts resemble and smooth butter, scraping down the sides as needed. This process can take a while, so be patient!

Once smooth, add the remaining ingredients into the food processor and blend to combine. Taste and add additional sweetener if desired.

Transfer the nutella into a glass container and allow to cool fully before sealing and storing in a cool dark place.
