Essential Ingredients for Classic Peanut Butter Banana Overnight Oats
You only need five main things for this recipe, which is why it’s so great! Don’t be tempted to use instant oats, though; they turn into mush way too fast. We need those good, hearty rolled oats to hold up to the chilling process.
Here’s what you need to gather for one perfect jar. If you’re doubling or tripling this batch for your week of Meal Prep Recipes, just multiply everything!
- 80g of rolled oats (the old-fashioned kind!)
- 200ml of your favorite milk (dairy or non-dairy works fine, trust me)
- 1 banana, sliced (save a few pretty coins for the top!)
- 30g of peanut butter (creamy is best for swirling purposes)
- 10g of chia seeds (these are crucial for thickness!)
If you’ve ever made my brown sugar maple version, you know how important ingredient quality is. If your peanut butter is too stiff, it won’t mix in properly, so make sure it’s relatively stir-able!

Tips for Perfect Classic Peanut Butter Banana Overnight Oats
Making these really is the easiest thing in the world—it’s about as Diy Overnight Oats as you can get! But even simple five-ingredient recipes can go from great to incredible with just a little know-how. Don’t just dump and run; take 30 extra seconds to stir things properly. If you just stir the peanut butter on the top, you’ll end up with a single, dense clump of nutty goodness at the bottom later, and that ruins the whole creamy swirl experience.
I always like to slightly warm my peanut butter for about ten seconds in the microwave first. It makes it flow like lava when you mix it in, ensuring it disappears perfectly into the milk and coats those oats wonderfully.

Ingredient Notes and Substitutions
Feel free to swap the standard milk, but be warned: thinner milks, like skim dairy milk or plain almond milk, might mean you need an extra half teaspoon of chia seeds or the oats will be a little soupy. If you can swing it, unsweetened soy or oat milk gives you the best creaminess! If you can’t do peanut butter? Cashew butter is an amazing swap, though it doesn’t have quite the same strong flavor profile. Remember that keeping a good balance of moisture is key, just like they talk about concerning superfoods in general over at Health Harvard.
Step-by-Step Instructions for Classic Peanut Butter Banana Overnight Oats
Okay, let’s get down to the fun part—actually assembling this beauty! I always use a wide-mouth mason jar because it makes stirring so much easier; dealing with a skinny jar when scraping things off the bottom is just a pain. You’re going to layer things slightly, but don’t stress about perfection because everything is going to mix together overnight anyway!
First thing: grab your jar and measure out the dry stuff. You’re tossing in the 80 grams of rolled oats and the 10 grams of chia seeds. I know, I know, chia seeds look like tiny little specks, but they swell up when wet and give you that perfect texture. Don’t skip ’em!
Next, we mix the liquids and the peanut butter. Pour in your 200ml of milk and then dollop in that 30 grams of peanut butter. This is where you need to stir like you mean it! You want to mix this whole base layer until that peanut butter is completely dissolved and you don’t see any major streaks left. Remember what I said about warming the peanut butter? Doing it now makes this mixing step a breeze. If you’re looking for a heartier baked version rather than the cold stuff, check out my simple baked oat breakfast recipe for some inspiration!
Once it’s stirred well, gently add your sliced banana right on top of the mixture. Don’t stir the banana in! We want those pretty banana chunks sitting nicely on the surface.
Finally, the magic part. Cover that jar tightly—a lid or some plastic wrap works—and pop it into the fridge. It needs a minimum of four hours, but really, you need to let it chill overnight, which means at least 240 minutes. That time lets the oats soak up all that creamy liquid. When you wake up, just give it a final quick stir to get your creamy swirl going, and enjoy your delicious, ready-to-eat breakfast!
Making Your Classic Peanut Butter Banana Overnight Oats Healthier
I love that this recipe is naturally filling, making it one of my favorite Easy Overnight Oats Healthy options, but I also know people look to customize for all sorts of goals! If you are counting macros or trying to slim down your portions, you have lots of easy swaps available. This formula is so solid, you can tweak it without ruining the final texture.
For example, if you’re aiming for something Overnight Oats Low Calorie, just use skim milk or unsweetened almond milk instead of whole milk. You still get all the flavor, just fewer calories! I’ve also found that using powdered peanut butter instead of the regular creamy stuff—just rehydrate it with a tiny splash of water before mixing—cuts the fat way down.

Boosting Protein in Your Classic Peanut Butter Banana Overnight Oats
Protein! That’s the secret to staying full until dinner, even with these Classic Peanut Butter Banana Overnight Oats. If you’re looking for an Overnight Oats High Protein boost, I have two favorite tricks. First, swap out half your regular milk for plain Greek yogurt. It gets so incredibly thick and creamy, you won’t even miss the extra liquid!
Second, and this is a big one: add a scoop of your favorite vanilla or unflavored protein powder right into the wet ingredients before stirring. You might need an extra splash of milk to balance it out, but the payoff is huge. Remember to keep your overall diet in mind, following great guidance like what you see from the American Heart Association!
Serving Suggestions and Overnight Oats Toppings for Classic Peanut Butter Banana Overnight Oats
Okay, so maybe you don’t eat your Classic Peanut Butter Banana Overnight Oats straight out of the jar with a soup spoon—though I totally do that sometimes! The beauty of this base recipe is how easily you can customize it later with different Overnight Oats Toppings. The toppings are where you can really change the whole experience, whether you want more crunch or an extra layer of sweetness.
If you like things crunchy, throw on a handful of chopped walnuts or pecans right before eating. That nutty crunch is amazing against the smooth oat base. For added texture and a little extra sweetness, a quick drizzle of honey or maple syrup (skip this if you’re watching sugar, though!) really wakes everything up.
If you want something totally different from coleslaw toppings, try adding some hemp seeds for healthy fats! If you are interested in other recipes, even savory ones like my apple cranberry coleslaw recipe, you know where to look!
Storage and Make-Ahead for Classic Peanut Butter Banana Overnight Oats
This is absolutely the best part of any Meal Prep Recipe—it holds up so well! Your Classic Peanut Butter Banana Overnight Oats will stay perfect in the fridge for up to three days, sealed tight in that jar. I usually don’t push it much past day three because the banana starts getting a little too soft for my liking.
If you’re making a big batch on Sunday for the whole week, just make sure you leave the banana slicing until the morning you plan to eat it, or maybe just add half the banana and save the rest for topping later. This keeps the texture just incredible all week!
