For as long as I remember, I’ve been OBSESSED with oatmeal. In college, I’d eat oatmeal every single morning with sliced bananas and drizzle of peanut butter on top — and yes you guessed it, a healthy dose of breakfast nostalgia is exactly what inspired these incredible overnight oats.

These peanut butter banana overnight oats are creamy, packed with 15g of protein thanks to siggi’s + peanut butter, and perfect for both kids and adults. Bonus, there’s absolutely no cooking required. Just stir everything together the night before and then get ready for bites of banana bread inspired heaven in the morning.

What are overnight oats?

Overnight oats are simply oats soaked in a liquid overnight until they expand and ‘cook.’ In this recipe, the oats soak up the milk and yogurt to create the creamiest texture. The banana adds a natural boost of sweetness, too! There’s no real “cooking” or heating required, so overnight oats make the perfect breakfast on hot summer days.

Mornings made better with overnight oats

Not only do these peanut butter banana overnight oats taste amazing, but they’re also packing the nutrition to keep you full and satisfied after breakfast. These overnight oats:

  • Pack in healthy fats: from creamy peanut butter and chia seeds.
  • Have over 15g of protein: thanks to siggi’s yogurt and peanut butter.
  • Are naturally sweetened & gluten free: just use gluten free rolled oats and a ripe banana!
  • Take just 10 minutes to prep: for an easy, nourishing breakfast you can enjoy on-the-go the next day!

Everything you’ll need to make peanut butter banana overnight oats

These protein-packed peanut butter banana overnight oats couldn’t be easier to make with such delicious, simple ingredients. Here’s everything you’ll need to make them:

  • Banana: you’ll mix the overnight oats mixture with mashed ripe banana for that yummy banana bread flavor and natural sweetness.
  • Milk: feel free to use any milk you’d like. I prefer almond milk.
  • siggi’s Yogurt: I love adding siggi’s Vanilla Yogurt for a little extra flavor, but plain works just as well. The yogurt adds the perfect boost of protein while making the peanut butter overnight oats super creamy and delicious.
  • Oats: we’re using rolled oats to keep a creamy texture. Be sure to use a gluten free brand if you need to keep the overnight oats gluten free.
  • Cinnamon: a little flavor booster to really bring out that banana bread flavor. YUM.
  • Chia seeds: just a tablespoon of chia seeds adds healthy fats, fiber and protein. Plus they thicken up the overnight oats for a wonderful texture.
  • Peanut butter: gotta love a little peanut butter mixed right in and drizzled in the layers (if you’d like). Win-win for extra healthy fats.

Make these peanut butter overnight oats your own

Looking to customize? So easy! Here are some ways you can jazz up these peanut butter banana overnight oats:

  • Add extra fruit: these overnight oats would be delicious with sliced strawberries, blueberries or raspberries for a little PB&J flavor.
  • Choose your nut butter: while the peanut butter gives these overnight oats such a delicious flavor, you can also use almond butter, cashew butter or sunflower seed butter. If you wanna get crazy, use chocolate almond butter/peanut butter.
  • Have fun with siggi’s flavors: while I love using their vanilla variety in this recipe, I think any of their berry flavors or even coconut would be amazing in here.
  • Go (coco)nuts: try using light coconut milk and even adding some unsweetened shredded coconut for extra creaminess and delicious flavor.
  • Toppings = love: don’t forget to top with extra banana slices, a drizzle of peanut butter and maybe my homemade granola recipe! Also, mini chocolate chips, anyone?
