Nutella

When chilled, Nutella becomes thick and hard to spread, robbing us of that smooth and creamy texture we know and love. Additionally, refrigeration can cause the oil in Nutella to separate from the mixture, resulting in an unpleasant layer of dryness on top.
Another reason to keep Nutella out of the fridge is that it tastes better at room temperature. Chilling can dull its flavors and make it less enjoyable to indulge in. By leaving it in a cool pantry or cupboard instead, you allow Nutella to maintain its delectable balance of sweetness and nuttiness.
