When I worked in New York City, this was my go-to breakfast 3-4 days a week. For hectic mornings, Peanut Butter Banana Overnight Oats are easy to make, perfect for meal-prepping, and you’ll save yourself ten bucks buying a healthy breakfast.

Simply make a batch of overnight oats for a day or the entire week. Transfer the oats to a mason jar and top with your favorite toppings.

What are Overnight Oats?

Creamy Overnight Oats are an easy, healthy, and quick breakfast for busy mornings.

This no-cook recipe can easily be made by combining old-fashioned oats with your choice of milk (dairy or nondairy), chia seeds, and flavorings of your choice. For this easy breakfast recipe, I used creamy peanut butter, mashed banana, vanilla extract, and cinnamon.

I personally love the classic combination of peanut butter and banana combo, however feel free to experiment and create a combo that you like.

The oats and then mixed well and stored in the refrigerator for up to 4 days. Once you’re ready to serve, top your overnight oats with your favorite toppings. I generally like granola along with some kind of fruit.

Ingredients

Peanut Butter Banana Overnight Oats Ingredients
  • Old-fashioned Oats: For overnight oats, I always use old-fashioned oats or rolled oats. Don’t use quick oats as they tend to get mushy.
  • Almond Milk: My choice for milk is usually unsweetened almond milk, however any nondairy milk or good ol’ dairy milk works.
  • Chia Seeds: Chia seeds are a great source of fiber and are rich in omega-3 fatty acids. Additionally, they’re a great source of antioxidants.
  • Banana: Bananas add sweetness and creaminess to the overnight oats.
  • Peanut Butter: I love using creamy peanut butter which adds creaminess and is a good source of protein.
  • Vanilla Extract: For a subtle vanilla flavor and sweetness, use pure vanilla extract.
  • Ground Cinnamon: Feel free to use ground cinnamon or even a touch of cardamom works great.

Expert Tips to Make the BEST Overnight Oats

→ Make sure you mix all the ingredients well before refrigerating.

→ Use a ripe banana, but not too ripe.

→ For the BEST results – refrigerate the oats overnight. This will result in a creamier texture.


Serving Suggestions

Here are some serving suggestions for overnight oats:

  • For some crunch – Granola, sliced almonds, chopped walnuts, and chopped pecans make great toppings.
  • For some fruit – sliced bananas, blueberries, chopped strawberries, chopped mango, and chopped peach all make great fruit toppings.
  • Feel free to add some hemp seeds on top.

Substitutions

Non-Dairy Milk – This recipe is vegan since it’s made with almond milk. Other non-dairy milk substitutions that would work are cashew milk, oat milk, soy milk would all work great.

For Vegetarian – Feel free to use dairy milk in your overnight oats. Whole milk, reduced-fat 2%, or low-fat 1% milk would all work well.

For Gluten-free – Old-fashioned oats are naturally gluten-free, but feel free to use certified gluten-free oats.

Peanut Butter Substitution – Almond butter, cashew butter, pecan butter. Any nut butter works.

Have a Nut Allergy? – You can replace peanut butter with sunflower butter or granola butter.


How to Store Overnight Oats?

  • Overnight Oats can be made and stored in the refrigerator for up to 4 days. The oats can be stored in an airtight container or individual jars. 
  • When you’re ready to eat, add your toppings and enjoy the overnight oats cold or bring them to room temperature by leaving the overnight oats out for about 30 minutes.

Frequently Asked Questions

1. Can I use quick oats instead of old-fashioned rolled oats?

You can, but I don’t recommend it. Quick oats will make the overnight oats mushier and softer. Additionally, they’re not as healthy as old-fashioned oats.

2. Are old-fashioned oats and rolled oats the same thing?

Yes.

3. Is this recipe gluten-free?

Yes. Oats are naturally gluten-free, however if you’re strictly gluten-free, make sure to use certified gluten-free old-fashioned oats.

4. Can I use another milk instead of almond milk?

Yes. I prefer unsweetened almond milk, however any nondairy milk or even regular dairy milk works.

5. What other fresh fruit toppings can I add to these overnight oats?

In addition to bananas, blueberries, strawberries, raspberries, and mangoes all work. Feel free to use seasonal produce, so in the fall and winter, you can use apples.

6. How can I make these high protein overnight oats?

Feel free to add protein powder when prepping the oats and before you refrigerate them. You may need additional liquid if you’re adding protein powder.

Note: To ensure this recipe is still vegan, make sure you use plant-based protein powder.

​Another option is adding Greek yogurt instead of protein powder. Just note, the recipe will no longer be vegan, but rather vegetarian.

7. Can I make overnight oats with instant oatmeal?

No. Instant Oatmeal will really impact the flavor and texture of the overnight oats, so no.

8. Which sweetener can I add to these overnight oats?

Personally, I don’t feel you will need additional sweeteners since the bananas are already sweet. If you must add sweetener, I recommend honey or pure maple syrup.
