Preheat the oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.
Peel the potatoes and cut them into large chunks. Place them in a large pot of salted water and bring to a boil.
Cook the potatoes for 15–20 minutes, or until they are fork-tender. Drain the potatoes and return them to the pot.
Add the butter, heavy cream, sour cream, garlic powder, salt, and black pepper to the pot with the potatoes. Mash until smooth and creamy. Adjust seasoning to taste.
Fold in the grated Parmesan cheese and half of the shredded cheddar cheese until well combined.
Transfer the mashed potatoes to the prepared baking dish, spreading them out evenly.
Sprinkle the remaining shredded cheddar cheese on top of the potatoes.
Bake in the preheated oven for 25–30 minutes, or until the cheese is melted and golden brown.
Remove the dish from the oven and let it cool for a few minutes. Garnish with chopped chives if desired before serving.
