The first time I made these Cookies & Cream Overnight Oats I thought they were dessert for breakfast — in the best way possible.
They hit that nostalgic cookie flavor while still feeling wholesome and easy to prep.
This recipe is a winner because it’s quick to assemble, stores beautifully, and delivers creamy texture with chocolate crunch.
If you want a grab-and-go breakfast that feels indulgent without the fuss, this is it.
Why You’ll Love This Recipe
- Ready in minutes the night before — perfect for busy mornings.
- Balanced: whole-grain oats + Greek yogurt protein + just enough sweet.
- Texture contrast: silky oats with crunchy cookie bits for every bite.
- Customizable: vegan, high-protein, or lighter versions are simple swaps.
The texture is the best part: the oats soak up milk and yogurt to become silky and spoonable, while the crushed chocolate sandwich cookies keep pockets of crispness and cocoa flavor. The cookie crumbs soften slightly overnight but still deliver that satisfying crunch and chocolate notes that make these feel special. A little vanilla and your sweetener of choice coaxes out a dessert-like aroma without overpowering the oats.
“Five stars — my kids polished off jars in the morning and asked for them again the next day. Perfect balance of creamy and crunchy!” — Emily, reader
Key Ingredients
Rolled oats
Rolled oats are the backbone here because they absorb liquid evenly and stay tender overnight without getting gummy. Use old-fashioned rolled oats over instant for the best mouthfeel; they hold structure and become delectably creamy after chilling.
Milk (dairy or non-dairy)
Milk controls the final consistency and flavor. Whole or 2% yields a richer, creamier mouthfeel; almond or oat milk keeps it lighter and vegan-friendly. If you want ultra-creamy oats, use half milk and half unsweetened almond creamer.
Greek yogurt (or any yogurt of choice)
Greek yogurt adds tang, richness, and protein, which helps this feel like a satisfying meal. Choose plain Greek for lower sugar and higher protein, or vanilla-flavored if you prefer sweeter oats. Dairy-free yogurts from coconut or almond brands work well too, but they may be thinner so reduce milk slightly.
Crushed chocolate sandwich cookies (like Oreos)
The crushed cookies provide the cookies-and-cream flavor and a chocolate crunch that sets this apart from standard overnight oats. Use a mid-range cookie — classic sandwich cookies work perfectly. For a less-sweet option, try dark-chocolate sandwich cookies or reduce the amount slightly.
Ingredients (full list)
- 1 cup rolled oats
- 1 cup milk (dairy or non-dairy)
- ½ cup Greek yogurt (or any yogurt of choice)
- 2 tablespoons honey or maple syrup
- 1 teaspoon vanilla extract
- ½ cup crushed chocolate sandwich cookies (like Oreos)
- Optional toppings: chocolate chips, extra cookie crumbles, or fresh fruit
Step-by-Step Instructions
Step 1: Combine oats and milk
In a mixing bowl or jar, stir together the rolled oats and milk until evenly combined.
Make sure there are no dry pockets of oats; thorough mixing helps consistent soak.
Pro Tip: For thicker oats, reduce milk by 2–3 tablespoons. You’ll know it’s right when the oats look fully coated but not soupy.
Step 2: Add yogurt
Scoop in the Greek yogurt and stir until the mixture is smooth and creamy.
Yogurt brings body and a tang that balances the sweetness.
Pro Tip: If your yogurt is very stiff, loosen it with a tablespoon of milk before stirring it into the oats for easier combining.
Step 3: Sweeten and flavor
Add honey or maple syrup and the vanilla extract, then mix well to distribute flavor.
Taste and adjust the sweetness; a little goes a long way because the cookies add sugar too.
Pro Tip: Use pure maple syrup for a rounded maple note, or honey for floral sweetness; liquid sweeteners integrate better than granulated sugar here.
Step 4: Fold in crushed cookies
Gently fold the crushed chocolate sandwich cookies into the oat mixture, reserving a few crumbs for topping.
This is where the cookies-and-cream identity forms.
Pro Tip: Crush cookies by hand in a zip-top bag with a rolling pin to control chunk size — a mix of small crumbs and larger chunks gives great texture.
Step 5: Portion into jars
Divide the mixture into individual jars or an airtight container for storage.
Press down lightly to remove air pockets, but don’t compress too much.
Pro Tip: Use clear jars so you can see the pretty cookie swirls in the morning — perfect for meal prep presentation.
Step 6: Chill overnight
Cover and refrigerate for at least 6–8 hours, or overnight, to allow the oats to hydrate and flavors meld.
Cold rest is what transforms raw oats into creamy overnight oats.
Pro Tip: If you’re short on time, refrigerate for 4 hours for a firmer but still tasty result; longer chilling deepens flavor.
Step 7: Stir and serve
In the morning, stir the oats to combine any separated liquid and top with extra cookie crumbles, chocolate chips, or fresh fruit.
Enjoy chilled, straight from the jar, or let sit at room temperature for a few minutes if you prefer softer texture.
Pro Tip: Add a splash of milk when serving if it seems too thick; stirring in preserves the cookie distribution and creaminess.
Expert Tips for Success
- Choose the right oat. Old-fashioned rolled oats are ideal for creamy texture and hold up well overnight. Steel-cut oats need different prep, and instant oats can turn mushy.
- Measure liquid to preference. Start with a 1:1 oat-to-liquid ratio for a spoonable, pudding-like texture, then tweak the next batch by ±2 tablespoons until you hit your favorite viscosity.
- Balance sweetness carefully. The crushed cookies add sugar, so start with 2 tablespoons of honey or maple syrup and taste in the morning. Adjust future batches based on how sweet your cookies are.
- Control cookie texture. If you like more crunch, fold in half of the cookie crumbs and reserve the rest for topping right before eating. Chunks will soften faster than fine crumbs.
- Layer for presentation. For jars meant to impress, layer oats with a sprinkle of cookie crumbs and a few chocolate chips between layers as you portion. It makes the jar look professional and keeps some chunks crisp.
- Use cold ingredients. Cold milk and yogurt help the oats hydrate evenly overnight; warm or room-temp ingredients can break down texture and encourage sogginess.
- Protein boost. Stir in a scoop of unflavored or vanilla protein powder when you add yogurt for higher protein content. Thin with a tablespoon of milk if it thickens too much.
- Avoid freezer burn. If freezing, leave a little headspace in jars and use freezer-safe containers to protect texture and flavor. Thaw gently in the fridge for best results.
- Make it vegan-friendly. Swap Greek yogurt for thick coconut or almond yogurt and use maple syrup; pick dairy-free sandwich cookies or use cocoa nibs for crunch if needed.
- Taste as you go. Small tweaks — a pinch of sea salt, a dash more vanilla, or a squeeze of orange zest — can elevate the flavor without adding complexity.
Storage & Freezing
Fridge storage: Store overnight oats in airtight jars or containers for up to 4 days.
Use glass jars with tight lids to preserve flavor and prevent fridge odors from migrating.
To reheat: If you prefer warm oats, transfer to a microwave-safe bowl and heat in 30-second intervals, stirring between bursts until warm.
Alternatively, let jars sit at room temperature for 10–15 minutes and stir in a splash of milk before microwaving.
Freezing: You can freeze prepared overnight oats for up to 2 months, but texture will change slightly after thawing.
Portion into freezer-safe containers, leaving some headspace, and freeze flat for easier storage.
Thawing frozen oats: Move jars to the refrigerator to thaw overnight, then stir and add a little fresh milk to revive creaminess.
If thawed oats seem grainy, whisk in a spoonful of yogurt and let sit for 10 minutes to rehydrate.
Best practices: Label containers with dates, and if you plan to freeze, use slightly less cookie crumb in the mix and reserve topping for after thawing to maintain crunch.
Variations & Substitutions
Cookies-and-cream protein upgrade: Add 1/2 scoop of chocolate or vanilla protein powder and swap Greek yogurt for high-protein skyr.
For a drier texture, reduce milk by 2 tablespoons and use a thicker yogurt.
Vegan & allergy-friendly: Replace dairy milk with oat or almond milk and use a dairy-free yogurt.
Choose allergy-friendly sandwich cookies or swap crushed cacao nibs and a touch of cocoa powder for a nut-free chocolate crunch.
Fruit-forward twist: Layer sliced bananas or strawberries in the jar for natural sweetness and freshness.
Berries help cut the richness and add a juicier contrast to cookie crumbs.
Spiced cookie version: Stir in 1/4 teaspoon cinnamon and a pinch of cardamom and use ginger- or cinnamon-spiced sandwich cookies.
This gives a warm, autumnal spin on the classic cookies-and-cream profile.
Frequently Asked Questions
Q: Can I use instant oats instead of rolled oats?
A: You can, but instant oats absorb liquid faster and can become mushy after overnight soaking. Rolled oats give the best creaminess and texture balance. If you must use instant, reduce milk slightly and check after 4–6 hours.
Q: How long will these overnight oats keep in the fridge?
A: Properly stored in airtight jars, they stay good for up to 4 days. The texture is best within the first 48–72 hours, after which the cookie crumbs soften more and the oats can thicken.
Q: Can I make a big batch for the week?
A: Yes. Multiply the recipe and portion into jars for 3–4 days of breakfasts. Add cookies later if you want more crunch on day 3 or 4.
Q: Are these high in sugar?
A: Sugar content depends largely on the cookies and sweetener you use. Using plain Greek yogurt and reducing added honey/maple syrup controls sugar. For lower sugar, use fewer cookie crumbs or switch to a less sweet cookie.
Q: What’s the best way to keep crunch in the toppings?
A: Reserve extra cookie crumbles and chocolate chips and add them right before eating. This guarantees the best contrast between creamy oats and crisp toppings.
