Peanut Butter Banana Overnight Oats

Be ready for the morning by making your breakfast the night in advance! Peanut Butter Banana Overnight Oats are my go-to easy and delicious breakfast, with old fashioned oats, almond milk, Greek yogurt, chia seeds, peanut butter, honey, and bananas.

Peanut Butter Banana Overnight Oats

When the weather starts to warm up, I change my morning oats from stovetop oats to overnight oats. It’s not surprising that a bowl of piping hot oatmeal doesn’t sound as appetizing when it’s 80 degrees out. I love oatmeal for breakfast, for their health benefits and the endless varieties I can make, so overnight oats are my solution to the changing seasons. While I do like to switch up the toppings and ingredients in my overnight oats, my go-to recipe is this Peanut Butter Banana Overnight Oats recipe. It’s easy, delicious, and never fails to keep me full until lunchtime!

Ingredients in Peanut Butter Banana Overnight Oats

Old Fashioned Oats – I always used old fashioned oats instead of quick oats. They’re a heartier texture and won’t get mushy like quick oats will.

Milk – I use whatever I have in the refrigerator – anything from 1-2% milk to unsweetened vanilla almond milk. I think coconut and oat milk would be good, too.

Chia Seeds – chia seeds add fiber, omega-3 fatty acids, and high-quality protein. They also absorb a lot of liquid and add a chewy texture to the oats.

Peanut Butter – my favorite is Smucker’s Natural peanut butter.

Honey – this adds a little but of natural sweetness. Maple syrup would work well, too.

Greek Yogurt – this gets added on the day of and adds the nutritional benefits of Greek yogurt including protein. I typically use plain whole milk Greek yogurt, but have occasionally used vanilla Greek yogurt!


Salt – just a dash is all that you need to really bring out the flavor.

Frequently Asked Questions about Overnight Oats

Can these be made multiple days in advance?

Yes! I like to make 3-4 days worth of oats ahead of time, adding the yogurt and bananas at the end when I’m ready to eat.

Can I substitute other nut butters for the peanut butter?

Definitely. Almond butter and cashew butter would work great in this recipe.

Can I use steel cut oats instead of old fashioned oats?

You can, but the texture will be different. Steel cut oats are chopped instead of flattened, like old fashioned oats, so they have a chewier texture. When I make steel cut overnight oats, I like to soak them longer – 18-24 hours instead of just 12, so they are a bit softer.

Are overnight oats vegan?

If you use almond milk and maple syrup instead of honey, then yes these overnight oats are considered vegan.

What is the difference between oatmeal and overnight oats?

Oatmeal is oats that are cooked in water or milk on the stovetop or the microwave. Overnight oats are simply combined with milk and other ingredients, and left to sit in the refrigerator overnight. The oats (and chia seeds in this recipe) absorb the liquid and soften on their own, without cooking.
