Cookies and Cream Overnight Oats are my go to breakfast for those mornings when I wake up hungry but also kind of grumpy. You know the feeling, you want something sweet and satisfying, but you do not want to cook or dirty a bunch of dishes. This is the jar I make when I want that classic cookies and cream vibe without turning breakfast into dessert overload. It tastes like a treat, but it still gives you the cozy, filling power of oats. And the best part is you can stir it together in about five minutes the night before. 
Why You’ll Love This Recipe
This is one of those recipes that makes you feel like you hacked the morning. You do a tiny bit of effort at night, then the next day you open the fridge and breakfast is sitting there waiting for you like a little gift.
Here is why I keep coming back to these Cookies and Cream Overnight Oats:
- They taste like dessert but still feel like a real breakfast.
- No cooking and no early morning mess.
- Easy to meal prep for a couple days at once.
- Great texture because the cookies soften just enough, but you can save some for crunch too.
- Super customizable depending on what you have in the pantry.
When I first started making overnight oats, I kept them pretty basic. Then I tried a more old school, cozy version and got hooked on the comfort factor. If you like that classic vibe too, you might enjoy this grandma style overnight oats recipe for a totally different mood, still simple and soothing.
Also, if you are making breakfast for kids or a picky partner, the word cookies usually does a lot of the convincing for you. I have served this to friends who swear they hate oatmeal, and somehow the jar comes back empty.
“I made this for two mornings in a row and I cannot believe it is actually oatmeal. It tastes like cookies and cream pudding, but it kept me full until lunch.”
What are overnight oats?
Overnight oats are oats that soak in liquid for several hours, usually overnight, so they soften without needing to be cooked. The oats absorb the milk, yogurt, and any flavorings you add, and by morning you get this thick, spoonable breakfast that feels creamy and filling.
The magic is really just time and absorption. I use rolled oats because they soften nicely while still keeping a little bite. Quick oats can get mushy, and steel cut oats stay too chewy unless you do a longer soak and add more liquid.
For Cookies and Cream Overnight Oats, the same idea applies. The cookie pieces soften a bit and flavor the whole jar, and the cocoa and vanilla notes come through like a milkshake situation, but breakfast style.
If you are new to this, here is the simple formula I follow:
Oats + liquid + something creamy + flavor + mix ins
Once you get that down, you can basically freestyle. I even do seasonal versions and tropical ones when I am tired of chocolate. Like, if you are a coconut fan, take a peek at these coconut cream oats for another creamy make ahead option.
What ingredients do I need?
Let us talk about what you actually need to make this happen. Nothing fancy, and you can find all of this at a normal grocery store. I usually make one serving in a jar, but you can easily double or triple it for meal prep.
My favorite ingredient list
- Rolled oats: the best texture for overnight soaking.
- Milk: dairy or unsweetened almond milk both work great.
- Greek yogurt: makes it extra creamy and adds protein.
- Chia seeds (optional): thickens it up and helps it feel more pudding like.
- Vanilla extract: cookies and cream basically needs vanilla.
- Cocoa powder (optional): I add a little for a deeper cookie flavor.
- Maple syrup or honey: just enough to make it taste like a treat.
- Crushed chocolate sandwich cookies: the fun part, plus extra for topping.
- Pinch of salt: sounds boring, but it boosts the flavor big time.
Here is how I make one jar, super casually:
In a jar or container, stir together 1/2 cup rolled oats, 1/2 cup milk, 1/3 cup Greek yogurt, 1 teaspoon chia seeds, 1/2 teaspoon vanilla, 1 to 2 teaspoons maple syrup, 1 teaspoon cocoa powder, and a pinch of salt. Then stir in 1 crushed cookie. Cover and refrigerate overnight. In the morning, add a splash of milk if it is too thick, then top with another crushed cookie for that fresh crunch.
A little tip from my kitchen: crush the cookies in your hand over the jar. It is oddly satisfying and you do not have to wash a cutting board. Also, if you like a stronger cookies and cream flavor, let the cookie pieces sit in the oats overnight, but save some bigger chunks for topping so you still get that bite.
And yes, I know this is a breakfast post, but I have to say it. These oats are amazing as an afternoon snack too. Sometimes I eat them right after a salty lunch like soup. If you are ever looking for a cozy dinner idea, this creamy potato and sausage chowder is one of those comforting bowls that pairs weirdly well with a sweet little jar after.
What substitutions can I make?
This recipe is very forgiving, which is perfect because most of us are working with whatever is already in the fridge. Here are the swaps I have tried and actually liked.
Easy swaps that still taste great
No Greek yogurt? Use regular yogurt, skyr, or a dairy free yogurt. If your yogurt is runny, use a bit less milk.
No chia seeds? Skip them. The oats will still soften, just a little less thick. You can also add a teaspoon of ground flax if you have it.
Different milk? Any milk works. Oat milk makes it extra creamy, almond milk keeps it light, and dairy milk tastes classic.
Sweetener options: Maple syrup, honey, agave, or even a little brown sugar are all fine. If your cookies are very sweet, you can use less sweetener.
Cookie choices: Chocolate sandwich cookies are the obvious pick, but I have used gluten free versions and they work. You can also use chocolate graham crackers in a pinch. It is a slightly different vibe, but still really good.
Add protein: Stir in a scoop of vanilla protein powder. If you do, add a little more milk so it does not get too thick.
One more tiny tip: if you want a stronger cream flavor without adding more sugar, add a spoonful of whipped cottage cheese or a bit more yogurt. It makes the jar taste like cheesecake filling, in a good way.
Is this recipe healthy?
I think of this as a balanced breakfast that leans fun. Cookies and Cream Overnight Oats can absolutely fit into a healthy routine, especially if you control the portion and use ingredients that support your goals.
How I keep it lighter but still satisfying
Oats bring fiber, which helps keep you full. Greek yogurt adds protein, which makes it feel more like a real meal and not just a sweet snack. Chia seeds add more fiber and healthy fats if you use them.
The main thing that can push it into dessert territory is how many cookies and how much added sweetener you use. My sweet spot is one cookie mixed in and one cookie crushed on top, but you can easily do half a cookie in the oats and still get that cookies and cream taste.
If you are watching sugar, try these tweaks:
Use unsweetened milk, use plain Greek yogurt, and keep the sweetener to 1 teaspoon or skip it if your cookies are sweet enough. You will still get that Cookies and Cream Overnight Oats flavor, just more mellow and breakfast appropriate.
Also, portion matters. A normal jar serving is filling. If you make a huge bowl, it is easy to accidentally turn it into two servings worth of calories.
Common Questions
Can I make Cookies and Cream Overnight Oats without yogurt?
Yes. Just replace the yogurt with more milk, or use a mashed banana for creaminess. It will be a bit less thick, but still tasty.
How long do overnight oats last in the fridge?
They are best within 2 to 3 days. After that, the texture can get too soft. If you are meal prepping, add the cookie topping right before eating for better crunch.
Do I have to use rolled oats?
Rolled oats give the best texture. Quick oats work if that is what you have, but expect a softer, more pudding like result. Steel cut oats usually need more time and more liquid.
Why are my oats too thick in the morning?
Chia seeds and oats both keep absorbing liquid. Just stir in a splash of milk until it is the consistency you like.
Can I warm them up?
Totally. Microwave for 20 to 40 seconds, stir, then add toppings. It will taste more like a warm cookies and cream oatmeal.
