Back to school time means busy mornings trying to get out the door on time. With two toddlers starting preschool (have you ever tried to get a toddler to do anything fast?), I'm relying on make-ahead breakfasts to make our mornings as smooth as possible. This peanut butter banana overnight oats recipe is one that I know I can always count on for the whole family to enjoy, and I feel good about serving it!

Why You'll Love These Overnight Oats

Everyone loves the classic peanut butter banana combination! The genius of overnight oats is that you get the wholesome goodness of oatmeal with the convenience of a grab-and-go breakfast that can be eaten warm. All with just 5 minutes of prep time and 7 simple ingredients. And they're filling enough to power you through a busy morning.

What Makes This A Healthy Breakfast?

We all know that oatmeal is super healthy - it's got soluble and insoluble fiber, for both digestive health and heart health. All that fiber also makes oatmeal filling while providing steady, lasting energy. Plain greek yogurt and milk offer up 22 grams of protein per serving, while delicious peanut butter and chia seeds provide healthy fat. This recipe also has no added sugar - it's sweetened only with banana (so it's baby friendly, for my BLW mamas!)

The Ingredients

Bananas - Provide natural sweetness and potassium. The more ripe (brown) the bananas, the sweeter your oats will be.
Peanut butter (of course!) - My favorite is peanut butter made with just peanuts and salt, such as Crazy Richard's or the Costco brand, for the best peanut flavor.
Plain Greek yogurt - Yogurt produces a thick, creamy texture and boosts the protein content without protein powder.
Milk - I use regular milk for the nutrition content. If you are going to use non-dairy milk, look for one with similar protein content as cow's milk, like soy milk.
Oats - Use rolled oats (old fashioned oats) for the best texture. If you don't have rolled oats, you can use quick oats or quick cooking steel cut oats.
Chia Seeds - For a little boost of omega-3s. If you don't like the texture of chia seeds, you can sub in ground flaxseed or just leave them out.
Cinnamon - Just a pinch for a sweet flavor without any actual sugar.

How To Make Peanut Butter Banana Overnight Oats

Mash the banana in a large bowl or jar.
Stir in the yogurt, milk and peanut butter.
Add the oats, chia seeds and cinnamon and stir.
Cover and refrigerate, or portion into individual servings, then cover and refrigerate overnight, or for at least 6 hours.
In the morning give it a stir and enjoy cold or warm.

Recipe Variations

For vegan, use your favorite non-dairy milk and yogurt. Look for high-protein versions to keep the protein content in the overall recipe high.
You can also use other nut butters, such as almond butter or mixed nut butter.
If you want the oatmeal to be sweeter, you can use vanilla yogurt, or add about 1 tablespoon of honey or maple syrup with the yogurt and milk.
Feel free to add any mix-ins, like chocolate chips or walnuts.

How Long Do Overnight Oats Last In The Refrigerator?

This recipe will definitely last a good 2-3 days in the refrigerator, so feel free to make a bigger batch if you'd like.
