Preheat the oven to 400 degrees and line a baking sheet with parchment paper.
Stab the potatoes with a fork all over, making sure to get holes around the entire potato.
Coat the entire potato lightly with olive oil. Cook the potatoes for 40-45 minutes, until the potato can easily be poked through with a fork.
While the potatoes cook, place all vegan sour cream ingredients in a food processor and blend until smooth and creamy.
Let the potatoes cool for about 10 minutes then cut the potatoes in half and scoop out the inside leaving about ΒΌββ of potato attached to the skin.
Coat the potato skins with olive oil, salt, and pepper and place the potato skins back in the oven for 10 minutes, until the skins are golden brown.
While the potato cooks, mix together the inside of the potatoes with the vegan sour cream and nut milk.
Remove the skins from the oven and place 2-3 tablespoons of the potato mixture into each potato skin and top with 1 tablespoon of cheese sauce. Place back in the oven for 5 minutes.
Remove skins from the oven, top with chives, and ENJOY!
