Getting a hearty breakfast together has never been easier than with this peanut butter cookie overnight oats recipe. Mix everything together in a bowl the night before, refrigerate overnight, and wake up to creamy peanut butter flavored cold oats that’re ready to grab & go. It’s a sweet dessert-flavored breakfast you can feel good about enjoying!

I’ve made no secret of the fact that I’m not a morning person.

Like, at all. And nobody else around here is either.

If we’re lucky, were rushing out of the house headed to who knows where for the day, hopefully with enough time leftover to grab a hot cup of coffee.

And if I ( or any of my progeny ) are lucky there might be some grab and go yogurts I remembered to buy on my last grocery store run, or there’s a freezer breakfast sandwich, or a breakfast burrito that we can take to heat and eat later.

This is why I’m oh so happy to have discovered the beauty of overnight oats.

There is no cooking required! None. Nada.

Simply stir together your ingredients the night before, store them in the refrigerator in an airtight container, go to bed, and wake up with not only a tasty treat waiting for you, but one that’s healthy too.

Does it get any better than that?

It does actually, because overnight oats are easy to flavor- so we made these ones taste like a peanut butter cookie.

A taste of dessert with minimal effort makes for the best start to the day!

Ingredients Needed

You only need a handful of easy ingredients to make a batch of these easy peanut butter cookie overnight oats.

You’ll need:

Oats – For this recipe you’ll want to use old fashioned rolled oats. Do not try to substitute with steel cut or quick cooking oats- neither will soak up the liquid properly.
Yogurt – Plain yogurt works best in these overnight oats since it won’t overpower the peanut butter flavor; however, you could substitute Greek yogurt if preferred.
Peanut Butter – Creamy, NOT crunchy, peanut butter
Salt – As with most of our sweet recipes, a pinch of salt is used because it intensifies and deepens the sweetness.
Sugar – Granulated white sugar.
Milk – I prefer 1-2% milk, but you could also use skim or whole. If using whole milk, you may need to add just a bit more since it’s thicker.
Garnish – Crumbled peanut butter cookies and miniature chocolate chips are both optional, but make a delicious topping when sprinkled on these oats before serving.

For extra help fueling your morning, you can add a scoop of protein powder- if desired.

How To Make

Making overnight oats is super easy, which is one of the reasons they’ve become a favorite breakfast for our house.

A little prep work the night before, and a creamy breakfast is ready & waiting when you wake up.

It’s genius.

To start, add all of the ingredients except the toppings to a medium sized mixing bowl.

Stir everything together until evenly combined.

Transfer the outs into two different containers- bowls, tupperware, mason jars or whatever you prefer.

Cover the oats and refrigerate overnight, until the oats have softened and absorbed a significant amount of the liquid.

When you’re ready to eat uncover the creamy overnight oats, sprinkle on your peanut butter cookie toppings, and dig in!

Storing

These peanut butter overnight oats can be store in an air tight container in the refrigerator for up to 5 days.

So you can make them the night before, or you could make a larger batch on Sunday night, and have breakfast ready to go all week!

However, overnight oats you’ve eaten out of will not keep. Those leftovers should be discarded.

What’re The Best Oats To Use For Making Overnight Oats?

Old fashioned rolled oats are the perfect oats to use for making creamy overnight oats in the refrigerator.

They’re steel cut oats that have been rolled out into flakes, and this allows them to perfectly absorb the liquid when left to sit without any heat or actual cooking require.

They soften, and leave you with the perfect creamy consistency and texture.

Do They Have To Be Eaten Cold?

While overnight oats are meant to be eaten cold, they don’t have to be.

If you’d prefer them on the warmer side, then transfer them to a microwave safe bowl and heat them for 35-40 seconds.

Stir them, and if not warm enough- heat them just until the chill’s knocked off.

Do My Overnight Oats Have To Actually Chill Overnight?

You don’t actually have to wait all night until the next morning to enjoy overnight oats.

Make sure to chill them for at least 2 hours before eating though.

This is the minimum time needed for the oats to soften and absorb the liquids.

TIPS & TRICKS

Do NOT try to substitute steel cut, or quick cooking oats, in this recipe.
These overnight oats can be eaten cold or warmed in the microwave until no longer chilled.
Want to go for extra indulgence? Top your oats with a drizzle of creamy peanut butter in addition to the crumbled cookies & chocolate chips.
As written, this recipe makes two hearty servings. It can easily be doubled or tripled to feed a larger family or to make enough for a week’s worth of breakfasts.
