I haven’t shared many oatmeal recipes yet since I just recently got into eating oats more often. These peanut butter overnight oats have been a surprising new obsession of mine since you can make them ahead and have them ready to go for breakfast.

They come out wonderfully creamy and delicious and pair perfectly with a warm cup of coffee. These overnight oats are loaded with protein and fiber thanks to the oats, peanut butter, and chia seeds. You can easily add more protein by mixing in some protein powder or Greek yogurt.

Ingredients and substitutions for peanut butter overnight oats

Old fashioned rolled oats – preferably rolled oats since they make the best base for overnight oats since they absorb the liquid so well. Steel-cut oats and quick oats will not work as well in this recipe.
Bananas – 2 medium bananas. I like to use not-quite-ripe bananas since they are not as sweet and won’t spike your blood sugar as very ripe bananas will. If you prefer to use ripe bananas then go ahead.
Almond milk – unsweetened almond milk is what I used, you can use any kind you like.
Creamy peanut butter – I love to use all-natural creamy peanut butter but any nut butter you like will work.
Chia seeds – to add some amazing fiber and protein to the oats and to help absorb the liquid.
Maple syrup – to add a little hint of sweetness.
Vanilla Extract – pure vanilla extract

Are Overnight Oats healthy?

How to make Peanut Butter Overnight Oats

You can easily make this recipe in less than 5 minutes with a few simple pantry ingredients.

Mash the bananas in a medium-sized bowl. Then add the peanut butter, vanilla, maple syrup, and chia seeds and mix that all together.
Add in the milk and oats and mix to combine everything.
Divide the oat mixture between 4-5 jars fitted with a lid and store them in the refrigerator for at least 8 hours or overnight.
Remove a container from the refrigerator, top with sliced banana and peanut butter, and enjoy!

It is so good and the easiest meal you can make in minutes and eat all week long! I love a good meal prep recipe.

Expert Tips

Use old-fashioned rolled oats. Instant oats and steel-cut oats do not work for overnight oats since they will not absorb the liquid as well. Make sure they are gluten-free if you need them to be since all oats are not gluten-free.
Creamy peanut butter is best! I like to use the drippy kind so it is easier to mix with the rest of the ingredients. Almond butter, sun butter, or cashew butter will also work in this recipe.
Mix the ingredients well. When you make overnight oats, you want to mix the ingredients well for the best result.
Add fun toppings like chopped nuts, fruit, nut butter, coconut flakes or chocolate chips. Part of the experience of enjoying overnight oats is adding toppings, so don’t skip it!

How long do overnight oats need to soak?

Overnight oats usually need to be soaked for about 8 hours or overnight. This depends on how you prefer the oats. The reason they need to sit is so the oats can soak up all of the liquid, which also gives them great flavor. If you are in a rush then you can let them sit for 4-6 hours but they may not be as flavorful.

How long do overnight oats last?

If you store them in an airtight container in the refrigerator then overnight oats should last about 5 days. They taste the best if eaten within 3 days but this recipe was great for up to 5 days. That is why overnight oats are such a great meal prep recipe since you can make a whole batch and enjoy them all week long!

Do you eat overnight oats hot or cold?

Overnight oats can be eaten hot or cold. You can warm up the oats in the microwave if you prefer. But the whole point of overnight oats is that you eat them cold like cereal. So before you warm them up try them cold first, you will be pleasantly surprised. They are DELICIOUS!
