These peanut butter banana overnight oats with chia seeds are so easy!
Real talk here. We don't have a lot of breakfast recipes on our website. You know why? All we basically eat are overnight oats for breakfast.
That's right..9 times of 10 I'm eating oats just like these. So we might just consider ourselves the overnight oats experts of the internet. 😉 We'll let you decide that.
Why this recipe?
We created our banana chia overnight oats using our super popular overnight oats with a yogurt and chia seeds base, which means you're getting a filling, high fiber, and high protein packed breakfast to keep you going all morning.
Eating a high protein breakfast has been a game changer while I've been working to build more muscle and for losing weight as an over 40 female.
Just make a batch of these on Sunday and you'll have 6 days of ready to go breakfasts on your way out the door!
My hunch is you love overnight oats too. Which is why you should get our recipes on your meal prep rotation like our apple cinnamon overnight oats, blueberry strawberry overnight oats, applesauce overnight oats, or our chocolate protein overnight oats. We have so many more recipes, which you can find right here!
What's in overnight oats?
Honestly, the skies the limit with overnight oats! They can be made without Greek yogurt, with protein powder, without chia seeds, or even just made with water. The amount of variations you can make are truly insane.
Here are the core ingredients you'll need for our high protein high fiber extra delicious recipe.
- rolled oats - just plain rolled oats here, the kind you'd use to make oatmeal. We used gluten-free oats.
- milk of choice- dairy milk or plant based milk like almond milk, coconut milk, or oat milk. We used unsweetened almond milk.
- Greek yogurt - We used nonfat Greek yogurt, 2% or 5% Greek yogurt would work well also. Or make these vegan with coconut or plant based yogurt.
- pure vanilla extract - a touch of vanilla gives a nice little flavor boost
- honey or pure maple syrup to add sweetness to the recipe.
- chia seeds - these can be left out but we love the extra boost of fiber and protein they give!
- sea salt - a pinch of salt brings out the flavor
Mix in: sliced bananas, peanut butter (or another type of nut butter), chocolate chips, and shredded coconut as both mix-ins and toppings. You can even mix in chopped walnuts for banana bread vibes.
Containers we recommend
- The containers we use the most and used in this recipe are these mason jars.
- For piling up toppings or making double portions, we love these bougie containers.
- If you want a cute, cheap set with lids and gold spoons, this vintage inspired mugs set is adorable! Great for coffee drinks too.
How to make overnight oats with bananas and chia seeds
Our way of doing things at home is to make the base recipe and to store it in the fridge in the bowl or to divide the oat mixture between 6 (8 oz) mason jars.
Then in the morning, when we go to eat the oats, the optional toppings get added.
- In a medium size bowl, combine the rolled oats, Greek yogurt, milk, vanilla extract, honey, chia seeds, and salt.
- Stir in the mashed banana, peanut butter, chocolate chips, and coconut flakes.
- You can either leave the oats mixture in the bowl, cover it, and place it in the fridge to set for at least 2 hours or overnight (8 hours). Or, you can divide the overnight oats into 6 cup size mason jars.
- Add more toppings in the morning! Sliced bananas, a drizzle of peanut butter, coconut flakes, chopped nuts, and/or chocolate chips. Enjoy!
Must know tips
- This is an easy recipe to adjust. Feel free to leave out the chocolate chips or coconut flakes to keep this recipe sugar free.
- Even the peanut butter is optional! We LOVE this base recipe too without any mix-ins at all.
- Adjust the sweetness based on your personal preferences. We keep it lightly sweet, so feel free to adjust it to taste.
- We use this same base recipe to make mixed berry oats and apple cinnamon raisin oats too.
- The oats will last in the fridge for up to 6 days.
Why do people put chia seeds in overnight oats?
Chia seeds are great in overnight oats because they add a good source of fiber and protein, which makes this a food that keeps you full all morning long. Chia seeds are great for digestion too and to help you stay "regular."
Chia seeds absorb liquid and become gel-like, which makes the oat mixture thicker and creamier. They add a mild nutty taste to any recipe.
What is the ratio of chia seeds to overnight oats?
The ratio of chia seeds to overnight oats we like to use in many of our single serving recipes is 1 ½-2 teaspoons per ½ cup of rolled oats and ½ cup of liquid.
Bananas in overnight oats: yay or nay?
Adding bananas in overnight oats provides natural sweetness and a creamy texture. They also add a great dose of potassium to help you get your day started, plus they increase the fiber in this recipe.
Again, even if this is a banana chia oats recipe, you can leave out the bananas at times and just eat our overnight oats base. Then add toppings to taste.
How do overnight oats help in weight loss?
Overnight oats are great for weight loss since they're super nutritious, high fiber when you add chia seeds, and they're packed with protein by mixing in a little Greek yogurt. Eating a fiber and protein rich breakfast digests slower which keeps you feeling full longer. From personal experience, eating more protein has helped stop by sugar cravings, which also makes it easier to shred extra pounds.
