Peanut Butter Oatmeal Ingredients

Creamy Peanut Butter - use the peanut butter of your choice for this recipe - I typically use unsweetened peanut butter that is just ground peanuts and salt, but any type of creamy peanut butter will work.
Steel Cut Oats - using steel-cut (also called coarse or pinhead oats) is a must! Rolled oats, which are processed steel-cut oats, do not stand up well for multiple hours in a slow cooker.
Milk - use the milk of your choice in this recipe. I typically use almond milk, but I've also used skim milk and oat milk as well.
Brown Sugar - just a small amount of brown sugar will add some delicious sweetness to the oatmeal! If you use unsweetened peanut butter, you may end up wanting to use a bit more.
Salt - you'll use a pinch of sea salt to season the oatmeal. You may want to add more after cooking, taste, and salt to your preference!

Tips for Making this Oatmeal

If your oatmeal seems a bit dry in the morning, add a little extra milk to it.
It's important to use steel-cut oats in this recipe - not rolled oats. Rolled oats will end up as a soggy mess after this many hours in a slow cooker.

Make Ahead & Storage

Storage - You can store leftover oatmeal for up to 4 days in the refrigerator in an airtight container.
To Freeze - Save oatmeal in the freezer for up to 3 months in a freezer-safe container.
Reheat - Reheat in the microwave in 1-minute increments or on the stovetop over medium heat. The oatmeal will be less moist after reheating, add a tablespoon of water or milk at a time till the desired consistency is reached.

Slow Cooker Oatmeal Add-Ins

Fruit - add berries (blueberries, raspberries, strawberries, etc), sliced banana, chopped kiwi or papaya, or any other fruit you enjoy!
Nuts - drizzle on extra nut butter or chopped nuts like almonds, walnuts, or pecans.
Garnishes - you can sprinkle on hemp seeds or chia seeds as well!
