Set your oven to 425°F and put a piece of parchment paper over a baking tray.

Place the chopped potatoes in a big pot and cover them with cool water. Bring it to a boil and let them cook until soft, about 15–20 minutes. Drain away the water completely.

Mash the warm potatoes in a large bowl until smooth (or use a ricer for better texture). Pour in 2 tablespoons of melted butter along with the cream, salt, pepper, and nutmeg. Stir thoroughly, then let the mixture cool down a bit. Gradually mix in the egg yolks, one at a time.

Spoon the potato mix into a piping bag fitted with a big star tip. Squeeze 12 swirled mounds (around 2½ inches across and 2 inches tall) onto the prepared tray, leaving space between each. Lightly brush the tops with the rest of the melted butter.

Pop the tray into the oven and bake for 20 minutes, or until the edges are golden brown. Sprinkle each with chopped parsley and serve while warm.
