Cookies and Cream Overnight Oats are my favorite answer to mornings when I want breakfast to feel fun, but I do not want to cook before coffee. I started making them on busy weekdays when plain oatmeal felt a little too predictable and a jar of chocolate sandwich cookies was sitting on the counter tempting me. Instead of choosing between something filling and something sweet, I mixed the two ideas together. The result tastes creamy, chocolatey, and nostalgic, yet it still has the satisfying texture of rolled oats and Greek yogurt.
What I love most is how little work happens in the morning. The night before, I stir oats, milk, yogurt, chia seeds, vanilla, cocoa powder, and crushed cookies in a jar. Then the refrigerator does the rest. By breakfast, the oats feel soft and thick, the cookie pieces melt into the creamy base, and the whole jar tastes almost like cookies and cream pudding.
These Cookies and Cream Overnight Oats also fit easily into meal prep. You can make several jars at once, adjust the sweetness, swap the milk, add protein powder, or keep the cookie topping separate for extra crunch. Better still, the recipe takes about five minutes to assemble. So when morning arrives and your schedule already feels full, breakfast is ready to grab, stir, and eat. It is simple, comforting, and just playful enough to make an ordinary weekday feel a little better. And yes, I happily eat a jar for an afternoon snack too sometimes.

Why You’ll Love These Cookies and Cream Overnight Oats
Overnight oats already make mornings easier, but the cookies-and-cream version feels much more exciting than a plain jar of oats and milk. You still get a creamy, filling breakfast, yet crushed chocolate sandwich cookies bring enough sweetness and chocolate flavor to make every spoonful feel special.
Breakfast Waits for You in the Fridge
This is the part that keeps me making overnight oats.
You do the work when you actually have a few quiet minutes, rather than when you’re trying to get out the door. Stir everything together after dinner, put the jar in the refrigerator, and breakfast waits there overnight.
Then, in the morning, you simply stir and eat.
If overnight oats have already earned a regular spot in your refrigerator, my grandma-style overnight oats offer a more traditional version for days when you want something cozy and familiar.
Meanwhile, these Cookies and Cream Overnight Oats land on the more playful side. The cookie crumbs soften into the oats and flavor the whole mixture, while a few fresh crumbs on top restore that satisfying crunch.
Creamy Without Cooking
Rolled oats soften as they absorb milk overnight. At the same time, Greek yogurt adds a thick, creamy consistency, and chia seeds absorb additional liquid.
As a result, you get something closer to pudding than dry oatmeal.
That texture matters with cookies and cream. A thin oat mixture doesn’t give you the same dessert-inspired feel, while an overly thick jar can turn pasty.
Fortunately, you can fix either problem easily. Add milk when the oats feel too thick, or add a spoonful of yogurt or extra chia seeds when you want them thicker.
Easy to Change Around
Maybe you want more protein. Add protein powder.
Maybe you don’t eat dairy. Use plant-based milk and yogurt.
Perhaps you’d rather keep the sweetness low. Use fewer cookies and skip the maple syrup.
Once you know the basic oat-to-liquid ratio, you can adjust the rest without turning breakfast into a science project.
For another creamy make-ahead option, my coconut cream oats move in a lighter tropical direction while keeping the same low-effort morning routine.
“I made this for two mornings in a row, and I still cannot believe it is oatmeal. The texture reminds me of cookies and cream pudding, but I stayed full until lunch.”
What Are Overnight Oats?
Overnight oats are rolled oats that soften in cold liquid rather than cooking on the stove.
You combine oats with milk and other ingredients, refrigerate the mixture for several hours, and let the oats absorb that moisture naturally.
By morning, the oats become soft enough to eat straight from the refrigerator.
Why Rolled Oats Work Best
Old-fashioned rolled oats give me the best balance of softness and texture.
They absorb plenty of liquid overnight, but they still hold their shape. Therefore, the finished jar feels creamy without turning into complete mush.
Quick oats work if that’s all you have. However, because manufacturers cut and roll them more finely, they soften faster and create a softer texture.
Steel-cut oats work differently. They stay much firmer and require more liquid and longer soaking. For this particular Cookies and Cream Overnight Oats recipe, I stick with rolled oats.
If you’d like another variation that changes both flavor and color, matcha overnight oats give the basic overnight-oat formula a completely different personality.
How Long Do Overnight Oats Need to Soak?
I prefer a full overnight soak, usually around 6 to 8 hours.
However, you don’t technically need to wait until the next day. After roughly 4 hours, rolled oats generally soften enough to eat.
A longer rest creates a thicker, more blended texture.
The cookie crumbs also soften more over time. So if you enjoy a very creamy cookies-and-cream base, add some cookie pieces before refrigerating. Then reserve fresh crumbs for the top.
Ingredients for Cookies and Cream Overnight Oats
You only need a small collection of familiar ingredients.
For one generous jar, I use the following:
| Ingredient | Amount | What It Does |
|---|---|---|
| Rolled oats | ½ cup | Creates the breakfast base |
| Milk | ½ cup | Softens the oats |
| Greek yogurt | ⅓ cup | Adds creaminess and protein |
| Chia seeds | 1 teaspoon | Thickens the mixture |
| Vanilla extract | ½ teaspoon | Adds classic cookies-and-cream flavor |
| Unsweetened cocoa powder | 1 teaspoon | Deepens the chocolate flavor |
| Maple syrup or honey | 1–2 teaspoons | Adds optional sweetness |
| Chocolate sandwich cookies | 1–2 cookies | Creates the cookies-and-cream flavor |
| Salt | Small pinch | Balances the sweetness |
Rolled Oats
Old-fashioned rolled oats remain my first choice because they soften while keeping a pleasant bite.
Don’t cook them first. They go directly into the jar dry.
Greek Yogurt
Greek yogurt gives the oats their thick, almost cheesecake-like texture.
Plain yogurt gives you more control over sweetness, while vanilla yogurt adds extra dessert-style flavor.
If you like adding dairy for extra creaminess and protein, overnight oats with cottage cheese show another interesting way to make make-ahead oats more substantial.
Milk
Dairy milk works, but so do most plant-based alternatives.
Oat milk gives the mixture an especially creamy texture. Almond milk keeps it lighter, while coconut milk adds a mild coconut note.
Use unsweetened milk when you want more control over added sugar.
Chia Seeds
Chia seeds aren’t essential, but I like what they do to the texture.
They absorb liquid overnight and help turn the oats into a thicker, spoonable mixture.
If you leave them out, you may want to reduce the milk slightly or add more yogurt.
Chocolate Sandwich Cookies
Use whichever chocolate sandwich cookies you already enjoy.
I crush one cookie into the oat mixture before chilling. Then I add another on top in the morning.
That combination gives you both softened cookies-and-cream flavor and fresh crunch.

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.

How to Make Cookies and Cream Overnight Oats
You don’t need any cooking equipment. A jar or covered container and a spoon will do the job.
Step 1: Add the Oats and Dry Ingredients
Add rolled oats, chia seeds, cocoa powder, and a pinch of salt to your jar.
Stir briefly.
Mixing the cocoa into the dry ingredients first helps prevent clumps later.
Step 2: Add the Creamy Ingredients
Pour in the milk, then add Greek yogurt, vanilla, and maple syrup or honey.
Stir thoroughly until you no longer see pockets of dry oats or cocoa powder.
Scrape the bottom of the jar as you stir because dry oats love hiding down there.
Step 3: Add Crushed Cookies
Crush one chocolate sandwich cookie directly over the jar.
I usually break it into a combination of fine crumbs and slightly bigger pieces.
Then stir those crumbs into the oats.
The smaller crumbs distribute chocolate-cookie flavor throughout the jar, while bigger pieces leave soft cookie pockets after soaking.
Step 4: Refrigerate
Cover the jar and place it in the refrigerator for at least 4 hours, although overnight gives me my favorite texture.
During that time, the rolled oats and chia seeds absorb liquid.
Meanwhile, the cookie pieces soften and flavor the creamy oat mixture.
Step 5: Stir and Adjust
In the morning, open the jar and stir.
If the mixture looks thicker than you prefer, add a splash of milk.
If it’s thinner than you like, stir in a spoonful of yogurt and give it several minutes to settle.
Then taste.
You can add another drizzle of maple syrup if necessary, although I usually find the cookies provide plenty of sweetness.
Step 6: Add Fresh Cookie Crumbs
Crush another chocolate sandwich cookie over the top immediately before eating.
This step gives you something crunchy against the soft oats.
You can also add a spoonful of yogurt, chocolate chips, cacao nibs, or berries.
Then grab your spoon.
That’s all it takes.
How to Get the Best Overnight Oats Texture
Overnight oats are simple, but texture makes a huge difference.
Don’t Add Too Much Milk at First
It is much easier to thin overnight oats in the morning than to fix a watery jar.
Start with the suggested ratio.
Then add extra milk after soaking if needed.
Stir Thoroughly Before Chilling
Don’t simply layer the ingredients and put the jar away.
The oats need contact with the liquid to soften evenly.
Stir until every oat looks coated.
Stir Again Before Eating
Some chia seeds settle, while thicker yogurt may stay in pockets.
A quick morning stir brings everything back together.
Save Some Cookies for the Morning
If you put every cookie crumb into the jar overnight, you’ll get great flavor but no crunch.
I always keep some separate.
For another breakfast that leans into chocolate while still using chia, my chocolate yogurt chia pudding makes a great alternative when you want to skip oats completely.
Cookies and Cream Overnight Oats Substitutions
The basic formula handles substitutions surprisingly well.
No Greek Yogurt
Use regular yogurt, skyr, cottage cheese blended until smooth, or dairy-free yogurt.
If your replacement contains more liquid than Greek yogurt, reduce the milk slightly.
No Chia Seeds
Skip them.
The oats will still soften.
For extra thickness, add more Greek yogurt or a teaspoon of ground flaxseed.
Dairy-Free Version
Use your favorite plant-based milk and dairy-free yogurt.
Also, check the cookie label because ingredients vary between brands.
Gluten-Free Version
Choose certified gluten-free rolled oats and gluten-free chocolate sandwich cookies.
Cross-contact matters for people who need to avoid gluten medically, so check every packaged ingredient rather than assuming.
Protein Powder
Add half to one scoop of vanilla or chocolate protein powder.
Because protein powder absorbs moisture, you’ll probably need more milk.
Start with an additional 2 tablespoons and adjust after chilling.
If protein-focused breakfasts are already part of your routine, high-protein pumpkin overnight oats give you another make-ahead option with warm seasonal flavor.
Sweetener
Maple syrup, honey, agave, or a small amount of brown sugar all work.
However, taste before adding a full amount because sandwich cookies already contribute sweetness.
How to Make High-Protein Cookies and Cream Overnight Oats
This recipe already gets some protein from Greek yogurt and milk, but you can increase it without changing the whole breakfast.
Add More Greek Yogurt
Increase the Greek yogurt slightly and reduce the milk.
This creates a thicker jar while adding more protein.
Add Protein Powder
Vanilla protein powder fits especially well because it reinforces the creamy side of the cookies-and-cream flavor.
Chocolate protein powder creates a more chocolate-forward version.
Stir it thoroughly so you don’t end up with powdery pockets.
Try Cottage Cheese
Blend cottage cheese until completely smooth and use it alongside or instead of some Greek yogurt.
The finished oats stay creamy, and you won’t get obvious cottage cheese curds.
Use Higher-Protein Milk
Dairy milk and some specialty plant-based milks provide more protein than standard almond milk.
Compare labels if protein matters to your breakfast plan.
Are Cookies and Cream Overnight Oats Healthy?
I think of this recipe as a practical breakfast with a fun flavor rather than a dessert pretending to be health food.
Rolled oats contribute fiber and carbohydrates. Greek yogurt contributes protein, while chia seeds add additional fiber and fats.
Then the cookies add sweetness and the flavor that makes the recipe feel like cookies and cream.
The balance depends on how you build your jar.
Keep Added Sugar in Check
Start with plain Greek yogurt and unsweetened milk.
Then decide whether you actually need maple syrup.
Often, one or two cookies add enough sweetness on their own.
Don’t Go Overboard With Cookies
One cookie stirred in and one on top gives plenty of flavor.
Adding five or six cookies turns the recipe into something much closer to dessert.
There’s nothing wrong with dessert. I just prefer knowing which meal I’m making.
Add More Protein When You Need It
Greek yogurt, protein powder, cottage cheese, or higher-protein milk can make the breakfast more substantial.
That can help the jar keep you satisfied for longer.
Cookies and Cream Overnight Oats Variations
Once you’ve made the basic version, you can have a little fun with it.
Chocolate Cookies and Cream
Increase the cocoa powder to 2 teaspoons and add a few mini chocolate chips on top.
Peanut Butter Cookies and Cream
Swirl 1 tablespoon peanut butter through the finished oats.
Chocolate cookies and peanut butter naturally work well together.
Strawberry Cookies and Cream
Add chopped strawberries in the morning.
The berries bring freshness and acidity, which balances the richer cookie flavor.
Mocha Cookies and Cream
Add a teaspoon of instant espresso powder or a splash of strong cooled coffee.
If coffee-flavored oats sound especially good, decadent mocha coffee overnight oats take that idea even further.
Lemon-Cookie Twist
For something completely different, skip the cocoa and add lemon zest with vanilla cookies.
If bright flavors sound better than chocolate some mornings, lemon overnight oats make an easy change of pace.
How to Meal Prep Overnight Oats
This recipe practically asks to become meal prep.
Line up several jars and add the ingredients assembly-line style.
Make Two or Three Jars at Once
Rolled oats continue softening as they sit, so I personally prefer making two or three days at a time rather than a full week.
Day one has the most distinct oat texture.
By day three, the mixture becomes much softer and creamier.
Keep Crunchy Toppings Separate
Cookie crumbs, nuts, granola, and cacao nibs soften in the refrigerator.
Keep them in a small container and add them immediately before eating.
Label Different Variations
If you’re making several flavors, a little label saves morning confusion.
Cookies and cream, mocha, vanilla berry, and peanut butter can all look surprisingly similar through a cloudy refrigerator jar.
How Long Do Overnight Oats Last in the Fridge?
For best texture, I like these oats within 2 to 3 days.
They may last longer depending on the freshness of your ingredients, but the oats and cookies continue softening over time.
Always keep them refrigerated in a covered container.
If anything smells or looks unusual, don’t eat it.
Can You Freeze Overnight Oats?
You can freeze plain overnight oats, but I don’t love freezing this particular cookies-and-cream version.
The cookie texture changes, and yogurt can sometimes separate slightly after thawing.
Because the recipe takes only about five minutes to prepare, I prefer making a fresh batch every few days.
Can You Eat Cookies and Cream Overnight Oats Warm?
Absolutely.
Despite the name, you don’t have to eat overnight oats cold.
Microwave the jar only if the container is microwave-safe. Otherwise, transfer the oats to a bowl.
Heat for about 20 to 40 seconds, stir, and continue warming if necessary.
Then add your fresh cookie crumbs afterward.
Warm Cookies and Cream Overnight Oats taste closer to creamy chocolate oatmeal, which I especially like during colder months.
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.
A sweet little breakfast win you can repeat all week
You get soft rolled oats, creamy Greek yogurt, chocolate-cookie flavor, vanilla, and just enough crunch when you save those final cookie crumbs for the top.
More importantly, breakfast requires almost no morning work.
Stir everything together the night before, refrigerate it, and give it one final mix when you wake up.
From there, make the recipe fit your own routine. Add protein powder when you want a more substantial jar. Use dairy-free ingredients when that works better for you. Add strawberries, peanut butter, or coffee when you’re ready for a different flavor.
The formula stays simple, while the possibilities keep breakfast interesting.
If you’d like to compare other cookies-and-cream versions, Eating Bird Food’s Cookies and Cream Overnight Oats and Jordo’s World Cookies and Cream Overnight Oats offer additional ideas.
For me, though, the best version remains the one waiting in the refrigerator when I wake up hungry.
