Why We Love This Recipe

Ingredients

See the recipe card for full information on ingredients and quantities.

ingredients for overnight oats with banana.
  • Rolled Oats: Old-fashioned oats are the preferred oats for this recipe. They soak up the liquid nicely leaving you with a creamy texture. I do not recommend quick-cooking oats or steel-cut oats.
  • Peanut Butter: For the best texture, use creamy peanut butter.
  • Milk: Dairy or non-dairy milk works. If using non-dairy milk, it’s best to stick with unsweetened.
  • Yogurt: Yogurt adds a nice creamy component to the overnight oats. You can use regular or Greek yogurt. Just make sure it’s plain yogurt.
  • Chia Seeds: They plump and absorb moisture as they soak, giving the oats a thicker consistency.
  • Honey: Sweetener is optional, but I love the way honey adds a slight sweetness to the oats.
  • Salt: Just a pinch of salt to balance out the flavor.

Substitutions and Variations

If you’re looking to switch up the flavors of your oatmeal breakfast, there are plenty of substitutions and variations you can make to keep things interesting. 

  • Milk: You can use any type of milk you prefer in this recipe. If you’re looking for a dairy-free option, try using almond milk, coconut milk, or soy milk. If you want a creamier texture, use whole milk or half-and-half.
  • Sweetener: If you don’t want to use honey to sweeten your oats, you can use maple syrup, agave nectar, or brown sugar instead. You can also omit the sweetener altogether if you prefer a less sweet breakfast.
  • Peanut Butter: If you’re allergic to peanuts or just don’t like the taste of peanut butter, you can use almond butter, cashew butter, or sunflower seed butter instead. You can also use crunchy peanut butter instead of smooth if you prefer a bit of texture in your oats.
  • Fruit: While bananas are a classic addition to overnight oats, you can use any type of fruit you like. Try adding sliced strawberries, blueberries, or raspberries for a fruity twist. You can also add diced apples or pears for a fall-inspired flavor.

How to Make

  • In a bowl, combine the oats, peanut butter, and milk. Mix in the peanut butter into the oats.

Recipe Tips

To make the perfect Peanut Butter Banana Overnight Oats, here are some expert recipe tips to keep in mind:

  • Use the Right Oats: When making overnight oats, it’s important to use the right type of oats to get the best texture. Rolled oats or old-fashioned oats work best because they absorb the liquid and soften overnight. Steel-cut oats or quick oats don’t work as well because they don’t absorb the liquid as well and can be too chewy or too mushy.
  • Add Other Seeds: Seeds are a great addition to overnight oats because they add extra fiber, protein, and omega-3 fatty acids. Add 1-2 tablespoons of sunflower, flax, or other seeds to your overnight oats for a nutritious boost.
  • Don’t Overmix: When you’re mixing the ingredients for your overnight oats, be careful not to overmix. Overmixing can break down the oats and make the mixture too mushy. Mix just enough to combine the ingredients and then let the oats sit overnight to absorb the liquid and soften.

Toppings

The toppings you choose for your banana and peanut butter oatmeal can take them to the next level. Here are a few ideas to try:

  • Our preferred way: sliced bananas with a sprinkle of cinnamon!
  • Chopped nuts, such as almonds, pecans, or walnuts
  • Shredded coconut
  • Cacao nibs or chocolate chips
  • Granola
  • Dried fruit, such as raisins or cranberries

Storage Instructions

Store leftovers in an airtight container in the fridge for up to five days. 

Keep the toppings in a separate container and cut them the morning you eat your breakfast instead of all at once. This will keep them fresh for longer. 

If your oats become too thick after refrigeration, you can add a splash of milk or yogurt to loosen them up.

Description

Overnight oats with peanut butter and banana just have to be the most delicious on-the-go breakfast. Incredibly easy to make and easy to customize too!

Ingredients

Units Scale
  • 1 cup old-fashioned oats (rolled oats)
  • 2 Tbsp. creamy peanut butter
  • 1 cup + 2 tbsp. milk (dairy or non-dairy)
  • 1/2 cup plain yogurt (Greek or regular)
  • 2 Tbsp. chia seeds
  • 2 Tbsp. honey (or maple syrup)
  • Pinch of salt

To Serve

  • Sliced bananas
  • Ground cinnamon

Instructions

  1. To a bowl, add oats, peanut butter, and 2 tablespoons of milk. Mix in the peanut butter into the oats. Back of a spoon works great for this step.
  2. Stir in yogurt, chia seeds, honey, salt, and the remaining milk.
  3. At this point, you can divide the mixture evenly between individual serving jars with a lid. Or simply leave the mixture in the bowl, cover with plastic wrap, and refrigerate overnight, or up to 5 days. The oats will soften overnight and the mixture will thicken. They can be enjoyed the next morning.
  4. When ready to serve, top with fresh banana slices and cinnamon. These oats are meant to be enjoyed chilled but if you prefer your oats warm, simply heat the oats in the microwave before adding the toppings.

Notes

  • Thickness of oats: If you prefer your oats more on the runny side, add an additional 1/4 cup milk.
  • Substitutions: See the post for a full list of substitutions.
