Spray the inside of a slow cooker with cooking spray.
Add chopped potatoes. Cover and cook 2-3 hours on high or 5-6 hours on low.
Add sour cream, milk, garlic, salt, and pepper to potatoes. Use a hand mixer to blend together all ingredients. (Please see note below recipe!) Give them a taste and add more salt if desired. Serve plain, or with any favorite toppings such as gravy, or cheese and bacon!
Notes
**This recipe can easily be doubled for large groups - just increase the cooking time by 1-2 hours. *
**You can also smash the potatoes if you prefer, I like to use the hand mixer because it is so FAST and easy and I can make them as smooth or as textured as I want to be mixing them for a longer or shorter time!
