How to make peanut butter banana overnight oats
Making overnight oats is incredibly simple and requires no cooking. Follow these two main steps for a delicious breakfast ready when you are.
- Combine the ingredients. In a bowl or a mason jar, mix the rolled oats, mashed bananas, peanut butter, almond milk, maple syrup, vanilla, cinnamon and chia seeds until well combined. Cover and refrigerate for at least 4 hours, ideally overnight, to allow the oats to soften and the flavors to meld.
- Serve and enjoy. Divide the mixture into two servings. Add your favorite toppings—banana slices, a spoonful of peanut butter, hemp seeds, chocolate chips, or granola—and enjoy cold, or heat briefly in the microwave for a warm, cozy version that tastes a lot like banana bread.
These oats are delicious straight from the fridge, but warming them for 30–60 seconds gives a comforting, warm texture and intensifies the banana-bread character. Both ways are great—try each and see which you prefer.
Toppings and mix-ins
One of the best parts of overnight oats is customizing them. Here are favorite toppings and add-ins that pair especially well with peanut butter and banana:
- Fresh fruit – extra banana slices, berries, or sliced apple for brightness.
- Nut butter – almond butter, cashew butter, or sunflower seed butter if you prefer.
- Nuts and seeds – chopped peanuts, almonds, walnuts, pumpkin seeds, or shredded coconut for texture and crunch.
- Granola – adds a crunchy contrast to the creamy oats; sprinkle on top just before serving.
- Sauces and dollops – a spoonful of chia jam, a swirl of caramel-style sauce, Greek yogurt, or a little whipped cream for an indulgent touch.
- Chocolate – cacao nibs or a few dark chocolate chips make these oats dessert-worthy while adding depth of flavor.
Boost protein by swapping one banana for 1/2 cup Greek yogurt, stirring in a scoop of protein powder, or adding a few tablespoons of cottage cheese. Adjust liquid if needed for your preferred consistency.
Prepping and storing
These overnight oats keep well in the refrigerator for 4–5 days, making them ideal for weekly meal prep. Store individual portions in wide-mouth mason jars or airtight containers for easy grab-and-go breakfasts. If the oats thicken too much after a few days, stir in a splash of milk before eating.
