1) Preheat oven to 425F. Line a rimmed baking sheet with 2 layers of aluminum foil and a spritz of nonstick vegetable oil spray. Wash the potatoes, and while wet, sprinkle with 1 teaspoon of the salt. Place on the baking sheet and bake for 55 to 60 minutes, until cooked through and very soft.
2) Carefully scoop the hot potato filling into the bowl of a stand mixer. Add the remaining salt, the pepper, vanilla bean paste, ground cardamom and preserves and mix at low speed, working up to medium-high, until the potatoes are whipped and smooth, about 10 minutes, stopping to scrape down the bowl as needed. Add the coconut cream a bit at a time and continue to blend until fully incorporated, about another 5 minutes.
3) Adjust the seasoning with salt and pepper. Serve immediately, or store in a covered container and refrigerate for up to 1 day. Reheat to serve.
