Peanut butter banana overnight oats are my favorite way to start the day. Savory, sweet, creamy, and so easy to make. You're going to love this oats recipe!

I could live off of these peanut butter and banana overnight oats, they're just so good! Packed with so much great flavor, not too sweet, and given the fresh taste of banana slices in every bite, these oats are irresistibly good!
This was actually the first overnight oats recipe that I created and from that branched off all of the others like Strawberries and Cream Overnight Oats,Peanut Butter Jelly Overnight Oats, and Chunky Monkey Overnight Oats.
That said, I still eat these oats at least once a week or more. I doubt that I'll ever get tired of them.

🥘 Ingredients
Old fashioned oats- This is the base of the recipe. These oats will soak up liquid overnight to soften without the need to cook them.
Milk- Use dairy milk or nondairy milk based on what your preferences are.
Greek yogurt- Adding greek yogurt will make the oatmeal thicker, creamier, and a bit healthier too.
Vanilla extract- This is a great flavor enhancer.
Maple syrup- Use maple syrup as a natural sweetener.
Chia seeds- This is optional, but adding chia seeds will help to get your oatmeal some more nutritional benefits.
Salt- A natural flavor enhancer.
Peanut butter- You will need some creamy peanut butter for added protein and flavor.
Banana- Use a ripe banana. But wait to add it to the oatmeal so it doesn't brown overnight.

🧾 Substitutions
Oats. I have had great success using old fashioned oats and steel cut oats as well as quick cook steel cut oats (the kind that are chopped into smaller pieces). The difference in texture is pretty minimal.
Milk. You can use whole milk, low fat milk, almond milk, coconut milk or any other milk of choice. Even water or coffee creamer can work well in a pinch. Unsweetened almond milk is our favorite.
Sweetener. Healthier sweetener options include honey and maple syrup but you can also choose to use agave or a low-carb liquid sugar substitute.
Yogurt. You can use any plain or flavored yogurt of choice. Our go-to is Greek Yogurt because it's healthier but regular yogurts can be used too. We really enjoy Honey flavored Greek yogurt (it's our favorite). You can also omit the yogurt and just add in another ¼ cup of milk.
🍴 Recipe Tips
Chia seeds are optional
Adding chia seeds is optional but can be a great way to get additional health benefits from your meal. They help to reduce your blood pressure and reduce your risk of heart disease.
Chia seeds will absorb some of the liquid in the oats, so in the morning they will be pretty thick. You can thin down your oats to your desired consistency by stirring in additional milk.
👩🏻🍳 Storage
Your overnight oats are good for 5 days in the fridge so if desired, you can meal prep for the week on Sunday and not have to worry about breakfast again until Saturday.
⏲️Make Ahead Instructions
You can eat your oats right after they've been mixed together, but the oats will be chewy. Letting them sit for at least 4 to 6 hours is ideal for a better texture and consistency as it will take several hours for the oats to absorb the liquid in the oats.
📖 Variations
If desired, you can heat your overnight oatmeal in a microwave safe bowl in the morning for about 1-2 minutes. While overnight oats are traditionally enjoyed chilled, they are just as tasty (if not more so) when warmed!
💭 FAQs
Nope. We recommend waiting overnight so you can wake up to the perfect bowl of oats, but if you like your oatmeal chewy then you can eat them immediately after stirring together, or after just waiting an hour or so.
Keep your overnight oats covered and stored in the fridge when not being eaten. This will help to keep them from spoiling and will allow them to taste delicious longer.
Absolutely! While chia seeds give a little extra thickening and add a lot of added health benefits, you can easily omit them if desired.
