This Nutella doughnut recipe is for baked doughnuts, not fried. These bite-sized little treats are baked in a mini muffin tray and injected with Nutella using a star piping nozzle right at the end. Whether you call them doughnuts or donuts- these little treasures are small enough to enjoy a few in each sitting. Bite into one and Nutella oozes out of the middle. They really are a yummy taste sensation.
