A Note from Kim
My Go-To Breakfast Lifesaver
I can’t even tell you how many mornings these peanut butter overnight oats have saved me. They’re creamy, filling, and feel like such a treat first thing in the morning. Almost like dessert for breakfast, but in a good-for-you way. I love how I can mix them up in just a few minutes the night before, pop them in the fridge for a quick soak, and wake up the next day to a ready-to-eat jar of cozy, nutty goodness. Perfect for busy mornings, school drop-offs, or when I just want to savor my coffee without rushing around the kitchen.
With love (and lots of good eats), 
I can’t get enough of these oats!! They’ve been my go-to for an easy, tasty breakfast while caring for my newborn, and I actually look forward to making them. I like adding a pinch of sea salt, a sprinkle of cinnamon, and cow’s milk (though coconut milk is amazing too). Definitely recommend!

Ingredients You’ll Need
When it comes to this peanut butter overnight oats recipe, every ingredient has a purpose—adding creaminess, texture, or a little extra nutrition. Here’s a quick breakdown of what goes into this recipe and why it all works together so well.
- Old-fashioned rolled oats: The best choice for overnight oats since they soften up nicely without getting mushy. Use certified gluten-free oats if needed.
- Plain Greek yogurt: Adds creaminess and protein; you can swap with mashed banana or applesauce for natural sweetness and a dairy-free, vegan option.
- Almond milk (or other milk of choice): Keeps the oats smooth and helps everything soak together. Any type of milk works here, so use what you like!
- Peanut butter: Brings in richness, flavor, and healthy fats. Try another nut butter, like almond or cashew butter if you prefer.
- Chia seeds: They thicken the oats while adding fiber and omega-3s. Don’t skip if you love that pudding-like texture!
- Toppings & mix-ins: Fresh fruit, granola, or cereal add crunch, texture and great flavor. Always wait to add toppings until just before eating.
- Optional sweetener: A drizzle of honey, maple syrup, or stevia lets you adjust the sweetness to your taste.
Make It Your Own
- Berry bliss: Stir in raspberries, blueberries, or strawberries for a fresh, fruity kick.
- PB&J: Stir in a spoonful of your favorite jam or swirl it on top before eating for that classic combo.
- Chocolate peanut butter: Add a spoonful of cocoa powder and a sprinkle of mini chocolate chips.
- Banana nut: Mash in ripe banana and top with toasted pecans for natural sweetness and crunch.
- Pumpkin spice: Stir in pumpkin purée, cinnamon, nutmeg, and a little maple syrup for cozy fall vibes. Try my pumpkin overnight oats next!

How to Make Peanut Butter Overnight Oats
This peanut butter oats recipe couldn’t be simpler, just 3 easy steps stand between you and a creamy, satisfying breakfast. Stir, chill, and top—it’s really that quick!
Step 1: Mix. Combine all ingredients (except toppings) in a jar or container with a lid, stirring until well blended.
Step 2: Chill and serve. Cover and refrigerate the mixture overnight, or at least 4 hours, so the oats soften and soak up the flavors. When ready to eat, give the oats a stir, add a splash of milk if needed, pile on your favorite toppings, and dig in!
Kim’s Recipe Tips
- Stir well: Make sure the peanut butter is fully mixed in so it doesn’t clump at the bottom of the jar. Warming it slightly before mixing helps. I like to use a natural peanut butter that’s drippy, so it’s easy to drizzle over the oats.
- Adjust thickness: If you like creamier oats, add a splash of milk before eating. For thicker oats, reduce the liquid just a bit when mixing.
- Sweeten to taste: Start with little or no sweetener, you can always add honey, maple syrup, or a packet or two of stevia before serving.
- Don’t add toppings too soon: Granola, cereal, or fresh fruit should go on right before eating so they stay crunchy and fresh.
- Double or triple the batch: Overnight oats are great for meal prep and keep well for about 5 days in the fridge, so make a few jars at once to save time on busy mornings.
Frequently Asked Questions
Yes, but the texture will be much softer, almost a pudding-like consistency. Rolled oats hold up best. Do not use steel-cut oats, as those are too hard.
Yes! Heat them in the microwave for 30–60 seconds, stirring and adding a splash of milk to the oat mixture if needed. I don’t warm up my overnight oats but I do like to take them out of the refrigerator about 20 to 30 minutes before enjoying just so they’re not quite so cold.
Any kind! Natural PB gives a rich, nutty flavor, while classic creamy peanut butter makes it extra smooth. You can even use sunflower butter, cashew butter or almond butter!

I actually have a question, what ingredients are in the middle? They are not listed in the recipe.
It’s just a layer of nut butter to look pretty for the pictures!
This has been in my breakfast rotation for the last 7 years. Absolutely love them!
This was my very first time trying overnight oats, and wow—I was so wrong about them! I always thought they were just an excuse to use cute Mason jars, but these turned out absolutely delicious. I warmed mine up a little and added apple and banana slices on top…so, so, so good!
tried this with variations, loved it, thanks
Loved this recipe! The ingredients are easy to get and I love that is so quick and easy to make and then you can just have it in the morning for breakfast. Perfect for moms on the go.
So delicious! Very simple. I substituted hemp seeds because I had them on hand and it worked well. Great recipe!!
I whipped this up so my kids would have something fast and filling before school, and it was a total hit! My younger daughter actually had a meltdown because her sister polished off the last of it. Safe to say, this one’s going on repeat.
So delicious, with both almond and peanut butter.

This was SO yummy. I used cashew butter, ground flax instead of chia seeds, and coconut milk. I topped with mango. Absolutely delicious.
This was delicious. I like to eat my overnight oats warmed up in the morning, so I heated them up in the microwave for 60 seconds before eating and it was like having a warm peanut butter cookie right out of the oven for breakfast.
