Overnight oats have been around for quite some time now—I’ve definitely made my fair share, from Dark Chocolate Overnight Oats to Pumpkin Pie Quinoa Overnight Oats and these peanut butter overnight oats. But it’s an idea I keep coming back to. Unlike some food trends that come and go, overnight oats have withstood the test of time because who doesn’t need a quick, easy, HEALTHY breakfast that’s ready when you are?!
Why I Can’t Get Enough of These Peanut Butter Overnight Oats
How much do I love these overnight oats? Let me count the ways!
- That PB + chocolate combo. It’s a classic for a reason—it’s the BEST. Although you don’t have to add the chocolate chips, it totally gives these oats peanut butter cup vibes. And when you can start your day with peanut butter cup flavor, you know it’s going to be a good one.
- So easy to make. All you need are a few simple ingredients and a few minutes of prep the night before. No cooking, no fuss—just mix, refrigerate, and enjoy your oats in the morning.
- Totally customizable. It’s very hard to go wrong with overnight oats. You can add mix-ins and toppings, adjust the texture and sweetness, and if you taste it and it’s not good, you can just keep adjusting!
What You’ll Need
I always have these ingredients on hand, which is another reason I love these peanut butter overnight oats! Scroll down to the recipe card to find the ingredient quantities and recipe instructions.
- Rolled oats – Also known as old-fashioned oats.
- Chia seeds – These thicken the oats a bit and also give you some fiber, protein, and omega-3s. If you’re not a big fan, try hemp hearts instead.
- Maple syrup – Or your sweetener of choice.
- Peanut butter – I like to use natural peanut butter made with only peanuts.
- Unsweetened almond milk – Or whatever milk you keep on hand in the fridge.
- Toppings – Chocolate chips and extra peanut butter.
How to Make Peanut Butter Overnight Oats
Here’s how easy it is to make these overnight oats.
- Combine. Add all of the ingredients except the toppings to a bowl or jar and stir.
- Refrigerate. Divide the oats into two jars if you’d like and refrigerate overnight.
- Serve. Add the toppings and dig in!
Tips and Variations
These peanut butter overnight oats are incredibly easy, but here are a few additional pointers.
- Adjust to your liking. You can add more or less sweetener, more or less milk to change the texture, and so on.
- Make it extra creamy. Add plain Greek yogurt to up the protein and creaminess of your overnight oats.
- Switch up the nut butter. Try almond butter, cashew butter, or sunflower seed butter for a nut-free option.
- Give it a protein boost. Add a scoop of protein powder. Chocolate will make your oats extra decadent, while vanilla or plain will let that peanut butter flavor shine.
More Topping Ideas
Sliced bananas are another of my favorites for topping these peanut butter overnight oats, but any fresh fruit you like will work. Chopped nuts and shredded toasted coconut are also excellent!
How to Store
Peanut butter overnight oats will last up to 5 days in the refrigerator, so you can prep a whole week’s worth of breakfasts on a Sunday night. Just be sure the oats are stored in a tightly sealed jar or airtight container.
