Ingredients You’ll Need
Gathering the ingredients for this Slow Cooker Peanut Butter Oatmeal Recipe is refreshingly straightforward. Each component plays a crucial role, from the hearty steel-cut oats providing that ideal chewy texture, to the peanut butter bringing in creamy richness and a subtle nutty depth. The milk of your choice adds moisture and creaminess, while a pinch of salt and brown sugar enhance the flavors, rounding everything out beautifully.
- 1 cup steel-cut oats: The base of the dish, steel-cut oats give a chewy, hearty bite that’s perfect for slow cooking.
- 4 cups milk of choice: Almond milk works wonderfully here, lending a smooth, nutty undertone and creamy texture.
- 1/3 cup creamy peanut butter: This adds rich flavor and luscious creaminess that melds perfectly with the oats.
- 1 tablespoon brown sugar: Just a touch of sweetness to balance the nutty flavors without overpowering them.
- Pinch of salt: Enhances all the flavors and prevents the oatmeal from tasting flat.
- Optional toppings: Peanut butter swirls, dried fruit, mixed nuts, sliced banana, or a dollop of jelly to personalize each serving.
How to Make Slow Cooker Peanut Butter Oatmeal Recipe
Step 1: Combine the Ingredients
Start by adding the steel-cut oats, milk, creamy peanut butter, brown sugar, and pinch of salt into your slow cooker. Give it a good stir until the brown sugar dissolves completely, ensuring the sweetness distributes evenly throughout the oats as they cook. This simple step sets the stage for a luscious, well-balanced oatmeal.
Step 2: Slow Cook to Perfection
Set your slow cooker to low and let everything cook for 6 to 7 hours, or choose high for 3 to 3 1/2 hours if you’re short on time. The slow cooking process allows the oats to soften gradually while the peanut butter melts and infuses every bite with its rich, silky flavor. Once done, give it a thorough stir to combine every ingredient harmoniously.
Step 3: Serve and Garnish
Once your Slow Cooker Peanut Butter Oatmeal Recipe is ready, serve it immediately while warm. This dish is a blank canvas for your favorite toppings — get creative and add texture and bursts of flavor with your preferred garnishes.
How to Serve Slow Cooker Peanut Butter Oatmeal Recipe

Garnishes
Topping your peanut butter oatmeal is half the fun. For a classic touch, add a spoonful of peanut butter or a handful of mixed nuts to boost the nuttiness and offer some crunch. If you love a fruity twist, dried fruit or fresh sliced bananas add natural sweetness and vibrant color. A dollop of jelly can bring a nostalgic peanut butter and jelly vibe that turns breakfast into a delightful treat.
Side Dishes
This oatmeal shines as a hearty centerpiece but pairs wonderfully with light side dishes. Fresh fruit salad or a glass of freshly squeezed orange juice balance the richness with bright, refreshing notes. For those looking for extra protein, a side of scrambled eggs or a yogurt parfait complements the creamy texture with contrasting flavors and nutrition.
Creative Ways to Present
For a special occasion or to simply brighten up your morning, serve the oatmeal in individual glass jars layered with peanut butter swirls and your favorite toppings neatly arranged on top. Garnishing with a sprinkle of cinnamon or cocoa powder adds an elegant touch. You can also transform leftovers into overnight oats by refrigerating and enjoying them cold or gently reheated the next day.
Make Ahead and Storage
Storing Leftovers
Your Slow Cooker Peanut Butter Oatmeal Recipe keeps beautifully in the fridge for up to 4 days. Store it in an airtight container to maintain its creamy texture and prevent it from absorbing other fridge odors. It’s a fantastic option for quick, nutritious breakfasts throughout the week.
Freezing
If you want to prepare even further ahead, this oatmeal freezes well. Portion it into individual containers or freezer bags, leaving some space for expansion. When frozen properly, it maintains most of its delicious texture and flavor for up to 3 months, making it a convenient option for busy mornings.
Reheating
Reheat your stored oatmeal gently on the stove over low heat or in the microwave, stirring occasionally to revive its creamy consistency. Adding a splash of milk or water while reheating helps loosen it up if it thickened too much in storage. You’ll have a warm, comforting meal ready in minutes.
FAQs
Can I use peanut butter powder instead of creamy peanut butter?
Yes, you can substitute peanut butter powder, but you’ll need to rehydrate it with a bit of water or milk to maintain the creamy texture. The flavor will still be delicious, though slightly less rich than creamy peanut butter.
Is it necessary to use steel-cut oats?
Steel-cut oats are recommended because they hold up well during slow cooking and have a great texture. Quick oats or rolled oats can become overly mushy. If you only have rolled oats, reduce cooking time and check for doneness frequently.
What kind of milk works best for this recipe?
Any milk works, from cow’s milk to plant-based options like almond, soy, or oat milk. Almond milk is a favorite as it adds a subtle nuttiness that complements the peanut butter beautifully.
Can I make this recipe vegan?
Absolutely! Use plant-based milks and make sure your brown sugar is vegan-friendly (some sugars are processed with bone char). The peanut butter is naturally vegan, so this recipe fits perfectly into a vegan lifestyle.
How do I prevent the oatmeal from sticking to the slow cooker?
To minimize sticking, lightly grease the slow cooker insert before adding ingredients. Stirring the mixture once or twice during the cooking cycle can also help, especially if cooking on the high setting.
Final Thoughts
Whether it’s busy mornings or relaxed weekends, the Slow Cooker Peanut Butter Oatmeal Recipe is your new go-to for a breakfast that’s both simple and irresistibly delicious. It’s like having a warm, cozy kitchen companion that fills your home with inviting aromas and your belly with comforting nourishment.

Ingredients
Main Ingredients
- 1 cup steel-cut oats
- 4 cups milk of choice (almond milk recommended)
- 1/3 cup creamy peanut butter
- 1 tablespoon brown sugar
- Pinch of salt
Optional Toppings
- Additional peanut butter
- Dried fruit
- Mixed nuts
- Sliced banana
- Dollop of jelly
Instructions
- Combine Ingredients: In the slow cooker, add the steel-cut oats, your choice of milk (almond milk suggested), creamy peanut butter, brown sugar, and a pinch of salt. Stir well until the brown sugar is fully dissolved and the peanut butter starts to incorporate with the other ingredients.
- Cook Slowly: Set the slow cooker to low heat and cook for 6 to 7 hours, or alternatively cook on high heat for 3 to 3 1/2 hours. During this slow cooking process, the oats will soften and absorb the flavors, while peanut butter blends thoroughly to create a creamy texture.

Notes
- Steel-cut oats work best due to their hearty texture and ability to hold up during long cooking times without turning mushy.
- You can substitute milk with any plant-based milk or dairy milk according to your preference and dietary needs.
- For a sugar-free version, omit the brown sugar or replace it with a natural sweetener like honey or maple syrup if cooking off heat.
- Be sure to occasionally check the liquid level if cooking on high to prevent burning, especially if your slow cooker runs hot.
- Add toppings just before serving to maintain their texture and flavor.
