Put a few scoops of vanilla ice cream in a bowl. Add 3 or 4 heaped teaspoons of nutella and pour in the milk. The amount of milk you add depends on you; add more milk for a smoother, runnier milkshake or add less for a thicker milkshake. I usually add enough to make a smooth milkshake. I don’t use proper measuremeants because it was an experiment which i wanted to try. Just adapt it until you think it’s right. Enjoy 🙂
