Ingredients

Making this peanut butter and banana overnight oats recipe is easy, all you need are a few basic ingredients listed below.

For the full ingredient measurements, scroll down to view the recipe card at the bottom of the page.

  • Banana, very ripe with some brown spots will give you a sweeter and creamier oats.
  • Peanut butter, preferable all natural. Use smooth or crunchy, both will work in this recipe.
  • Almond milk, or milk of choice. Non dairy milk to keep this recipe vegan.
  • Rolled oats, or old fashion oats, they hold their shape and create a better texture.
  • Chia seeds, mixing in some chia seeds in the overnight oats will add a creamy texture and extra nutrients. They are high in fibre, antioxidants and protein.
  • Maple syrup, or other liquid sweetener like agave syrup. Brown sugar or coconut sugar can also be used. 
  • Chocolate chips, I use vegan dark chocolate chips but any kind will work. A little chocolate flavour goes great with the banana and peanut butter in this overnight oats recipe.
  • Optional toppings, yoghurt, peanut butter or peanuts, chocolate chips and sliced banana.

See recipe card for quantities.

Hint: Another tasty, crunchy topping is granola. Use store bought or try this Air Fryer Granola or this Chocolate Banana Granola.

Substitutions and Variations

  • Gluten-free – Oats are naturally gluten-free, but they may contain traces of gluten. For a gluten free oats, use a certified gluten-free rolled oats brand that can be found in the gluten-free section of the grocery store. 
  • Banana – A mashed banana will add flavor, sweetness and add a creamy texture to the overnight oats. Another alternative to the banana, is to use applesauce, or check out this applesauce overnight oats recipe.
  • Extra protein – Mix in 2-4 tablespoons of protein powder, chocolate or vanilla flavor works great! If the protein powder is very sweet, reduce the amount of maple syrup.
  • Vegan – To keep this overnight oats recipe vegan, make sure to use a plant-based milk like almond milk or oat milk, and chocolate chips if using.
  • Sweetener  – The ripe banana will add a lot of sweetness in addition with a little maple syrup. Brown sugar or coconut sugar are other great alternatives to the maple syrup. Taste the overnight oats and add more sweetener if desired. 
  • Milk – The recipe calls for almond milk, but any milk of choice can be used. 
  • Chocolate – Instead of chocolate chips, a chopped chocolate bar also works great. For a healthier alternative, cacao nibs can also be used. For double chocolate flavor, see this Chocolate Peanut butter overnight oats.
  • Nut butter – This recipe uses natural peanut butter. Smooth or crunchy both works. Other great options are creamy almond butter or cashew butter or this homemade Pecan Almond Butter. For a nut free overnights oats recipe, use sun butter or leave it out all together. 
  • Nuts – Add some chopped nuts of choice to add a little crunch. Chopped peanuts, walnuts, pistachios, pecans or hazelnuts are good options.

Storage

This banana and pb overnight oats is great for meal prep because it keeps for a long time. Store in an airtight container in the fridge for about 4 days. You can also double the recipe to make 4 portions. Or why not try this Banana Chocolate Overnight Oats recipe or this Chocolate Peanut butter overnight oats.

When the overnight oats are stored in the fridge for a few days, the consistency will become thicker because the oats will keep soaking up the liquid. If needed, stir in a little milk before serving.

Freezing overnight oats will change the texture, so it is not recommend.

Top Tip

I like to wait to add the topping until ready to serve, especially if it is bananas slices that would become brown and mushy. Give the overnight oats a good stir after being stored in the fridge and add your favorit toppings.

Another tip is, before adding the natural peanut butter, stir it well in the jar until smooth and creamy to prevent lumps.

Also try this Chocolate Baked Oatmeal recipe, or these delicious Banana bread baked oats that are perfect for meal prep!

FAQ

Can I use quick oats instead of rolled oats?

Yes, but I don’t recommend it. The texture will become very mushy since the quick oats have a much finer texture.

Can you serve overnight oats warm?

Yes! This banana overnight oats recipe can also be served warm.
Heat one portion in a microwave safe bowl in 30 sec intervals, until it is piping hot and the chocolate chips are melted. For a creamier texture, stir in a little extra milk or serve with a little milk poured over the oatmeal. Add your favorit toppings and enjoy!

Can I make overnight oats without chia seeds?

Yes, the chia seeds are optional, they help create a thicker and creamier texture and a little extra nutrient. They can also be left out.  

How does overnight oats last in the fridge?

This overnight oats with banana and peanut butter can be kept in the fridge for up to 4 days which makes it great for meal prep! Store the oats either in individual containers, or in one large airtight container. Keep in mind that the longer the overnight oats are stored in the fridge, the more liquid the oats will continue soak up, resulting in a thicker texture. If needed, stir in a little extra milk before serving.
