Craving dessert for breakfast? What if you could dig into a creamy, chocolatey treat first thing in the morning and still feel good about it? Oreo Overnight Oats make that dream a reality—combining the comfort of cookies and milk with the powerhouse nutrition of oats. It’s indulgence and practicality in one spoonful.

This no-cook breakfast option is perfect for those who want something sweet, satisfying, and stress-free. Whether you’re rushing out the door or savoring your coffee slowly, these overnight oats fit seamlessly into your morning. Think of it as dessert you don’t have to wait for.

Preparation Phase & Tools to Use

Before you whip up your Oreo Overnight Oats, let’s make sure your kitchen is stocked with the right tools. Here’s what you’ll need:

Mason jars or sealable containers: These are perfect for assembling and storing the oats overnight. Their compact size and airtight seal make them fridge-friendly and portable.
Mixing bowl and spoon: While some prep directly in the jar, using a bowl first ensures all the ingredients are evenly combined.
Measuring cups and spoons: Accuracy is key when it comes to getting the perfect oat-to-liquid ratio.
Refrigerator: It does the real magic, soaking the oats to that creamy consistency while you sleep.

Having these tools ready makes the preparation smooth and fuss-free, so you can get to the fun part—digging in.

Ingredients for the Oreo Overnight Oats

Old-fashioned rolled oats: The base of the recipe, these absorb liquid overnight for a creamy texture. They’re also a great source of fiber and keep you full longer.
Milk (dairy or plant-based): This softens the oats and helps meld all the flavors. Choose your favorite—almond, oat, or whole milk all work.
Greek yogurt: Adds creaminess and a boost of protein to make the oats feel more indulgent.
Chia seeds: These tiny seeds thicken the oats and add a dose of healthy fats and fiber.
Maple syrup or honey: A touch of natural sweetness brings out the dessert-like flavor.
Vanilla extract: Enhances the overall flavor with a warm, aromatic note.
Crushed Oreo cookies: The star ingredient—bringing in that signature chocolate-vanilla taste and delightful crunch.
Salt (a pinch): Just enough to balance and highlight the sweetness.

How To Make the Oreo Overnight Oats

Step 1: Create the Creamy Base

In a mixing bowl, combine rolled oats, chia seeds, Greek yogurt, milk, maple syrup, vanilla extract, and a pinch of salt. Stir thoroughly to ensure everything is evenly mixed.

Step 2: Add the Oreo Magic

Gently fold in crushed Oreo cookies. Leave some chunks for texture—you want a bit of crunch and cream in each bite.

Step 3: Transfer and Refrigerate

Spoon the mixture into mason jars or your preferred containers. Seal them tightly and refrigerate overnight or for at least 6 hours.

Step 4: Serve and Top

The next morning, give the oats a quick stir. Top with an extra dollop of Greek yogurt, a drizzle of maple syrup, and a whole Oreo or more crushed cookies for garnish.

How to Serve and Store Your Oreo Overnight Oats

To serve, enjoy your Oreo Overnight Oats straight from the jar or transfer it to a bowl for extra toppings and flair. Add crushed Oreos, a swirl of Greek yogurt, or even a spoonful of peanut butter for a fun twist. It’s best served chilled, but you can let it sit at room temperature for 10 minutes if you prefer it slightly softened.

For storing, these oats are at their best within 3 to 4 days when kept in the fridge in an airtight container. That makes them perfect for meal prepping your breakfast for the week. Just prep a few jars on Sunday night, and you’ll have dessert-style mornings ready to go.

Frequently Asked Questions

Can I use steel-cut oats instead of rolled oats?

Not recommended for this recipe. Steel-cut oats require a longer soaking time and won’t yield the same creamy texture.

Are Oreo Overnight Oats healthy?

They can be! While Oreos add a sweet indulgence, the oats, chia seeds, and Greek yogurt bring in fiber, protein, and healthy fats. You can always reduce the cookie amount or use low-sugar alternatives.

What if I don’t like Greek yogurt?

You can substitute it with regular yogurt, a dairy-free option, or even a bit more milk. It might slightly change the texture but still works great.

Can I make this recipe vegan?

Yes! Use a plant-based yogurt, non-dairy milk, and check that your cookies are vegan (many Oreos are).

Do the oats need to be cooked?

Nope! That’s the beauty of overnight oats. They soak up the liquid and soften while chilling overnight—no cooking needed.

Can I freeze Oreo Overnight Oats?

It’s best not to. Freezing affects the texture, especially with cookies and yogurt. Stick to refrigerating for fresh results.
