Preheat the oven to 400 degrees F.
Use a sharp paring knife to make a few slashes all over the potatoes. Place them in an 8 x 8 x 2-inch pan. Bake until very tender when pierced with a fork, 45 to 50 minutes. Remove from the oven, and let cool slightly.
Slice the potatoes in half. Use a spoon to scoop the flesh out, making sure to leave a 1/4-inch border inside the potato skins so that they hold their shape. Place the skins back into the baking pan.
In a medium bowl, combine the sweet potato filling, coconut cream, cream cheese, 1 teaspoon of the chives, salt, and nutmeg. Use a hand or stand mixer to beat the potatoes until they are well mixed and fluffy. Spoon the filling back into the skins.
To make the topping, add the walnuts and oats to a mini food chopper or food processor. Pulse a few times until coarsely chopped. Stir in the maple syrup. Sprinkle the topping evenly over the filled potato skins.
Bake until the filling puffs up and the topping is golden, 25 to 30 minutes. Garnish with the remaining chives before serving.
