Slow Cooker Peanut Butter and Jelly Oatmeal made with steel-cut oats, makes the best, hearty, healthy breakfast! With only 5 minutes of prep, you can prepare peanut butter and jelly steel-cut oatmeal that will cook overnight for an easy breakfast that is ready when you wake up.
If you love steel-cut oats, check out Instant Pot Steel Cut Oats, Baked Carrot Cake Oatmeal, and Overnight Strawberries and Cream Steel Cut Oatmeal.

I think you all know by now, that I LOVE oatmeal.
We eat varieties of oatmeal such as Overnight Apple Pie Oatmeal, Peanut Butter Banana Oatmeal, and Baked Sweet Potato Oatmeal, nearly every weekday at my house.
Yet, I have never shared with you my kids' all-time favorite oatmeal recipe--peanut butter and jelly oatmeal.
Slow Cooker Peanut Butter and Jelly Oatmeal
Friends, this PB&J Oatmeal is the MOST requested breakfast recipe at my house. It even outranks my Hot Cocoa Oatmeal and Strawberry Cheesecake Pancakes!
I am not surprised, though, as this hearty bowl of oatmeal is studded with pockets of sweet jelly and creamy peanut butter--I mean it is just a classic combination that is ALWAYS a winner!
And while it is my kids' favorite oatmeal, it is also a favorite of this mom, as well--because it takes me all of 5 minutes to make and cooks OVERNIGHT--so we can wake up to breakfast!
How to Make Crockpot Steel Cut Oatmeal
I have shared with you several recipes for Slow Cooker Steel Cut Oatmeal, like Strawberries and Cream Oatmeal and Maple Cinnamon Oatmeal. I just love that with just a few minutes of prep work, I can set my crockpot to cook through the night and wake up to breakfast being made--it is almost as good as being served breakfast in bed. ALMOST!!!
Peanut Butter Steel Cut Oatmeal is incredibly easy to make, as well. Just follow these simple steps:
- Grease your slow cooker with coconut oil or a cooking spray.
- Pour in steel-cut oats.
- Pour in your milk, water, and seasonings.
- Set your slow cooker to low and go to bed!
- Upon waking, dollop the oatmeal with peanut butter and jelly and mix until combined.
- Dish up for a perfect start to your day.
Key Ingredients in Peanut Butter and Jelly Oatmeal
One of the many reasons I love oatmeal is because oats themselves are healthy. BUT, what you mix into your oatmeal is crucial to building a healthy balanced breakfast, as well.
Take a look at the ingredients I use to build a healthy bowl of oatmeal:
- Steel Cut Oats--full of fiber and protein
- Milk--a source of calcium, vitamin D, and protein
- Chia Seeds--provide a good source of omega-3 fatty acids and fiber
- Banana (optional)--I use a ripe banana in this oatmeal to sweeten the oatmeal while it cooks. It is not necessary, as the jelly will sweeten the oatmeal too, but is a great way to make this steel-cut oatmeal sweet naturally.
- Peanut Butter
- All-Fruit Jelly--be sure to use a jelly made without added sugar or artificial sweeteners.
Notes on Steel Cut Peanut Butter Oatmeal
- Remember to grease the inside of your slow cooker so the oatmeal will not stick to your pot--I use coconut oil as it does not burn as easily as butter and tastes delicious with nut butter.
- Be sure to use STEEL CUT OATS (or sometimes labeled Irish Oats) regular or quick-cooking oats will not work in the slow cooker as this recipe is written.
- If you have an allergy to peanut butter, feel free to use almond butter or sunflower seed butter. Both are equally as tasty.
- Any jelly or jam works in this steel-cut peanut butter oatmeal recipe. I do recommend using jellies that are sweetened with fruit juice, like my Homemade Chia Jam, to cut back on added sugars. Of course, freshly sliced fruit, like bananas, or strawberries would be delicious on this PB&J oatmeal too.
- You can use any percent milk you would like in overnight steel-cut oatmeal, or even non-dairy milk if allergic to milk.
- If you happen to have leftover steel-cut peanut butter oatmeal, place it in a sealed container in the fridge. Warm the oatmeal up with a splash of milk, as needed. Peanut Butter Crockpot Oatmeal will keep in the refrigerator for 3-5 days, which makes this a great recipe to use for meal prep on the weekend.

Can I make this on my IP slow cooker mode? Thank you!
Kristen Chidsey
Technically, yes. However the slow cooker function on the instant pot is my least favorite function. I walk through how to convert slow cooker recipe to instant pot recipes though if interested--just it is not as efficient as a slow cooker. For this particular recipe, adjust your instant pot to “normal” on the slow cooker function and cook for as the recipe calls to cook on low (8 hours). However, I would suggest you make this recipe pot in pot and follow my Instant Pot Steel Cut Oats recipe--it will be done in a fraction of the time. You will need to half the recipe to cook pot in pot in 6 quart instant pot though. Hope that helps--happy to help you more to convert this to and Instant Pot recipe 🙂
