Nothing beats waking up to a bowl of warm oatmeal that has been gently simmering overnight. Slow cooker oatmeal recipes are perfect for busy mornings or when you’re craving a cozy start to the day. This version infuses creamy peanut butter and sweet bananas, creating a breakfast treat that feels deliciously indulgent without the fuss.

Ingredients

- 1 cup steel-cut oats
- 3½ cups water or milk of your choice
- 2 ripe bananas, mashed
- 2 tablespoons creamy peanut butter
- 1 tablespoon honey (or maple syrup)
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
- Optional toppings: sliced banana, chopped peanuts, extra drizzle of peanut butter
Instructions
Begin by preparing your slow cooker with a light coating of cooking spray or a thin layer of oil—this helps prevent the oats from sticking. Next, combine the steel-cut oats, water (or milk), mashed bananas, peanut butter, honey, vanilla extract, and salt directly in the slow cooker. Stir everything together to ensure the oats are evenly dispersed in the liquid.
Set the slow cooker to low, cover, and let the oats cook for about 7–8 hours. If you prefer a quicker preparation, set it on high and cook for 3–4 hours. During cooking, you can stir occasionally if you like a smoother texture, but it’s not necessary. You’ll know the oatmeal is done when it’s thick, creamy, and the oats are soft. If the oatmeal seems too thick toward the end, stir in a touch more liquid until it reaches your desired consistency.
Just before serving, give the oatmeal a final stir to blend any remaining liquids. Spoon it into bowls, then top each serving with fresh banana slices, a sprinkle of chopped peanuts, and an extra dollop of peanut butter for an added boost of flavor.
Whether you’re feeding a busy household on a weekday or indulging in a lazy weekend brunch, these Peanut Butter–Banana Bliss Slow Cooker Oats will satisfy. The recipe welcomes customization—try adding cocoa powder for a chocolatey twist or switching peanut butter for almond butter for a different nutty dimension.
This dish offers a comforting hug in a bowl, rich in fiber and protein to keep you feeling nourished and content. Enjoy the freedom of having breakfast waiting for you, and experiment with flavors to find your perfect slow-cooked oatmeal match.
