Cover peeled potatoes with cold water in a large pot. Bring to a boil and cook until they're fork-tender, about 15-20 minutes. Drain thoroughly.

Rice the potatoes directly into a mixing bowl (or mash until completely smooth). Stir in 2 tablespoons melted butter, cream, salt, pepper, and nutmeg until well combined. Let cool slightly before mixing in egg yolks one at a time.

Transfer potato mixture to a piping bag with a large star tip. Pipe 12 mounds (about 2½ inches wide and 2 inches tall) onto your prepared baking sheet, leaving space between each. Brush tops with remaining melted butter.
