Store your homemade nutella in an airtight jar or container in the refrigerator. It will keep well in the fridge for a week or so, and at room temperature for 3 days. You can enjoy it straight from the fridge for a thick buttery consistency or at room temperature if you prefer a creamier softer spread. For the best consistency and to lengthen the shelf life of your vegan chocolate spread, I recommend storing it in the fridge and taking it out to sit at room temperature for about an hour before serving.
