Peel the potatoes. Be sure to rinse off any dirt that is left on the potatoes after peeling. Cube into 1/2-1 inch pieces. Add to the slow cooker.
Pour over water to cover the potatoes but do not fill water to the brim of the slow cooker, at least leave an inch.
Place the lid on the slow Cook on HIGH for 4 hours.
When the cooking time is up, drain the water off the potatoes. I do this with 2 potholders, using the lid to hold the potatoes in, but leaving a crack for the water to come out.
Add the stick of butter to the drained potatoes. Bury it into the potatoes while you set up a handheld mixer. Blend the butter into the potatoes on medium speed, then add the heavy cream, salt and pepper (if you are using it). Blend until smooth and fluffy. Add additional cream (or milk) if needed. (Be careful not to scratch up your slow cooker with the mixer, avoid hitting the sides or bottom with the beaters). You can use a potato masher if you do not have a hand mixer.
Taste and see if you want to season with additional salt.
Serve and enjoy!

Notes
Can I use a different kind of potato?
Yes, you can use gold or red potatoes in this recipe.
Be sure to cut them in half-inch cubes, if cut too big they will take longer to cook.
Can I leave the skins on the potatoes?
If you are short on time or love mashed potatoes with skins on you can leave them on!
Be sure to scrub your potatoes well before dicing (especially russets).
Can I use cream cheese?
You can add a box of cream cheese to this recipe instead of heavy cream if desired.
You will need to add a splash of milk to thin out the potatoes.
How long can I keep these on the warm setting after being prepared?
2-3 hours, stirring often.
Add extra cream, milk or butter if they start to dry out.
Variations:
Cheesy - Add 1 cup of sharp cheddar cheese to the potatoes and top with 2 more cups of cheese. Place the lid on top and let the cheese melt for 10 minutes.
Loaded Mashed Potatoes - Serve the potatoes buffet style with bowls of cheddar cheese, bacon, green onion, and sour cream on the side for guests to serve themselves.
VelveetaCheese - Cut the heavy cream in half in this recipe. Add 8 ounces of velveeta cheese and mix in. Then top with the remaining velveeta cheese (cube it small and spread it out). Let melt for 15 minutes.
Lower fat - Cut the butter in half. Omit the heavy cream and use fat-free milk in its place.
Garlic - Add 1 teaspoon of garlic powder while blending the potatoes for a garlic punch!
