Heat the oven to 350°
Place baking potatoes on a cookie sheet and place on middle rack of oven. Bake until done. Depending on the size it should take around an hour.
When potatoes are done, remove from the oven and allow to cool for about five minutes.
Cut each potato in half and scoop most of the flesh into a bowl. I like to leave a little flesh on the skin, it helps them keep their shape.
To the potato in the bowl add the butter, sour cream , salt, pepper, roasted garlic and most of the cheddar cheese. With an electric mixer, mix until combined.
Spoon the mixture back into the potato skins, top with the leftover cheddar cheese and a sprinkle of chopped chives.
Put back in the oven until warmed through and you are ready to serve them.
