Ingredients You’ll Need

The ingredients here are wonderfully straightforward yet essential in delivering the perfect balance of taste, texture, and a bit of that playful Oreo magic. Each element contributes to making the oats creamy, flavorful, and delightfully textured with crunch and cocoa notes.

Rolled oats: The hearty base that soaks up all the delicious flavors and creates that classic overnight oats texture.

Chia seeds (optional): These add thickness and a subtle crunch while boosting the nutrition content.
Unsweetened almond milk: A light, dairy-free liquid that blends everything smoothly without overpowering the flavors.

Plain Greek yogurt: Adds creaminess and a subtle tang, balancing the sweetness perfectly.
Unsweetened cocoa powder: Brings deep chocolate richness that pairs wonderfully with the Oreos.

Maple syrup: Natural sweetness to enhance the chocolate and balance the slight bitterness of cocoa.
Vanilla extract: A subtle floral note that ties all the flavors together beautifully.
Chocolate sandwich cookies: The star ingredient—crushed Oreos give the dish a playful crunch and that signature flavor.

Pinch of sea salt: A little salt heightens the sweetness and intensifies the chocolate notes.

How to Make Oreo Overnight Oats

Step 1: Mix the Dry Ingredients

Start by combining your rolled oats, chia seeds, cocoa powder, and a pinch of sea salt in a mason jar or a mixing bowl. This step ensures the dry ingredients are evenly distributed, setting a flavorful foundation before you add the wet ingredients.

Step 2: Stir in the Wet Ingredients

Next up, add the almond milk, Greek yogurt, maple syrup, and vanilla extract. Stir everything together until you get a smooth, creamy mixture with no clumps. This creates the luscious oat base that will soak overnight and transform into a delicious breakfast.

Step 3: Fold in Crushed Cookies

Gently fold in 1 to 2 crushed Oreo cookies, saving a few pieces for garnish later on. Be careful not to over-mix here, as you want to keep some of that delightful Oreo texture intact throughout the oats.

Step 4: Cover and Chill

Seal your jar or bowl tightly and pop it into the refrigerator for at least 4 hours, ideally overnight. This chilling period allows the oats and chia seeds to absorb the liquid, soften, and develop that signature creamy, pudding-like texture.

Step 5: Serve and Top

In the morning, give your Oreo Overnight Oats a good stir to blend any settled ingredients. Top with the reserved crushed cookies, a drizzle of extra yogurt, or even some chocolate chips for an extra special touch that will make every bite irresistible.

How to Serve Oreo Overnight Oats

Garnishes

Adding toppings is where you can really personalize this dish. Beyond crushed Oreos, try adding fresh berries, a dollop of whipped cream, or a sprinkle of chopped nuts for an exciting contrast in texture and flavor. These little extras not only brighten the presentation but add layers of taste that make breakfast feel like a treat.

Side Dishes

Oreo Overnight Oats pair beautifully with a simple fresh fruit salad or a glass of chilled cold brew coffee. If you want something heartier, a side of scrambled eggs or avocado toast complements the creamy oats perfectly, balancing indulgence with savory satisfaction.

Creative Ways to Present

For a stylish twist, serve your Oreo Overnight Oats in clear glass jars or small dessert bowls to showcase the beautiful layers and crushed cookie bits. Layering it with extra yogurt and drizzles of maple syrup creates an eye-catching parfait look that’s sure to impress guests or add excitement to your own breakfast routine.

Make Ahead and Storage

Storing Leftovers

Oreo Overnight Oats keep wonderfully well in the fridge for up to 3 days when stored in an airtight container. This makes it a perfect grab-and-go breakfast or snack option for busy mornings or when you want something quick but delicious.

Freezing

While freezing overnight oats isn’t typically recommended due to texture changes, if you do freeze them, expect a bit of separation upon thawing. To enjoy, thaw them overnight in the refrigerator and give a good stir before eating. Adding fresh toppings after thawing can refresh the texture and flavor nicely.

Reheating

Oreo Overnight Oats are best enjoyed cold, straight from the refrigerator, but if you prefer them warm, gently microwave in short bursts, stirring in between to avoid overheating. Just keep in mind that warming may melt the cookie bits a bit, changing the texture but still delicious in its own way.

FAQs

Can I use regular milk instead of almond milk?

Absolutely! You can substitute almond milk with any milk you like, including dairy milk or other plant-based options. Just choose your favorite based on taste and dietary preferences.

Are the chia seeds necessary?

Chia seeds are optional but highly recommended if you want thicker, more pudding-like oats. They absorb liquid and add healthy omega-3 fats and fiber, boosting both texture and nutrition.

Can I make Oreo Overnight Oats gluten-free?

Yes, just be sure to use certified gluten-free oats and check that your chocolate sandwich cookies are gluten-free as well. There are many great gluten-free cookie options available to keep this treat safe and delicious.

How many crushed cookies should I add?

Adding 2 to 3 crushed cookies works well for flavor and texture, but feel free to adjust based on how cookie-packed you want your oats. Saving some for topping gives a nice visual and textural pop in the morning.

Can I prepare this recipe without Greek yogurt?

Yes, you can swap the Greek yogurt with plant-based yogurt or even omit it altogether, though it adds creaminess and a slight tang that balances the sweetness beautifully. If you skip it, consider adding a little extra milk to maintain the right consistency.

Final Thoughts

If you’ve been looking for a breakfast that feels like a little celebration first thing in the morning, you simply have to try Oreo Overnight Oats. They are nourishing, simple, and downright delicious—combining chocolate, creaminess, and that iconic cookie crunch all in one jar. Once you make them, you’ll see why this has become a favorite for so many, and I hope they become one of yours too!
