Imagine waking up to a creamy bowl of warm, peanut-buttery oats studded with ripe bananas and a hint of vanilla. These overnight slow cooker oats take the fuss out of busy mornings—simply let them cook while you sleep, and wake up ready to dive into a hearty, comforting breakfast.

Ingredients

- 2 cups old-fashioned oats
- 4 cups milk (dairy or your favorite plant-based option)
- 2 tablespoons smooth peanut butter
- 2 ripe bananas, sliced
- 1 tablespoon honey or maple syrup (optional, for added sweetness)
- 1 teaspoon pure vanilla extract
- Pinch of salt
- Optional toppings: extra banana slices, chopped peanuts, fresh berries
Instructions
Add the oats, milk, peanut butter, and banana slices to your slow cooker, stirring gently to combine and break up the peanut butter. If you like your oats a bit sweeter, mix in a drizzle of honey or maple syrup, along with the vanilla and salt.

Cover the slow cooker and set it to low heat. Let the oats simmer overnight for about seven to eight hours. In the morning, stir the oats to incorporate any peanut butter that has settled and to ensure the banana slices are blended throughout. Scoop the oatmeal into bowls and add your favorite toppings. A few extra banana slices, a sprinkle of chopped peanuts, and a handful of fresh berries all add a nice finishing touch.
Whether you’re a busy parent, a health-conscious student, or someone seeking an easy, cozy breakfast, these hearty oats offer both convenience and flavor. Thanks to their high fiber and protein content, peanut butter–banana slow cooker oats will keep you satisfied through the morning. You can experiment with different sweeteners, milk alternatives, or even swirl in a bit of cocoa powder for a chocolatey treat. In any case, the convenience of preparing everything the night before ensures you’ll have a nourishing breakfast waiting for you—no rushing required.
