Why You'll Love Crockpot Oatmeal
- Crockpot peanut butter oatmeal is super simple & quick to pull together! Measure your ingredients and plop them into the slow cooker, and you'll be on your way to a delicious breakfast.
- A wonderful filling and cozy meal - perfect for a chilly morning.

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!

How to Make Crockpot PB Oatmeal

- Step 1: Combine the oats, milk, peanut butter, brown sugar, and salt in a slow cooker. Stir till the sugar has dissolved.

- Step 2: Cook on low for 6 to 7 hours or high for 3 to 3 ½ hours.

- Step 3: Stir till the peanut butter has combined with all the ingredients. Serve and garnish with optional toppings.
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!
