It's easy to make creamy mashed potatoes by baking them first in the oven. I've found it adds more depth to the flavor, and then you scoop them out and mix with milk, cream and plenty of butter

The ingredients are:
6 russet potatoes
1 cup cream
1 cup milk
Some garlic confit, that’s optional but I think add a nice subtle flavour to the dish
200g Butter cut into cubes
Salt and Pepper
And some chopped chives
