Start by cutting the peeled potatoes into thin strips.
Transfer all of them to a large bowl, add enough water to cover everything, a few ice cubes and mix everything very well.
Then, using a strainer, remove all the potatoes from the bowl, draining the water.
In a large skillet over medium to low heat, add the vegetable oil and let it heat up.
Add the potatoes we prepared and fry them until golden brown.
Remove them from the skillet and drain the excess oil on a plate lined with paper towels.
Next, transfer the French fries to a nice jar or container of your choice.
Add Nutella to taste and finish by sprinkling powdered milk to taste.
Serve.
