Creamy, chocolatey, and loaded with cookies-and-cream goodness, these Oreo Overnight Oats are the ultimate way to enjoy dessert for breakfast—without the sugar crash. They’re easy to prep, surprisingly nutritious, and 100% kid (and adult) approved!
Dessert Meets Breakfast (With a Healthier Twist)
Let’s be honest: the only thing better than Oreos is Oreos for breakfast. But before you start picturing a sugary crash and empty calories, let me introduce you to these Oreo Overnight Oats—a wholesome, protein-rich, fiber-filled way to get your cookies-and-cream fix first thing in the morning.
These oats are inspired by the classic cookie, but with a nutritious twist. Rolled oats and chia seeds provide the fiber, Greek yogurt adds protein and creaminess, and a little cocoa powder gives you that deep chocolate flavor.
Crushed chocolate sandwich cookies layered throughout? That’s the fun part—because balance is everything, especially when you’re feeding little ones (or your own inner child).
You can prep them the night before for an effortless morning treat, and they’re endlessly customizable. Add protein powder to boost the macros, or go dairy-free with plant-based milk and yogurt.
However you make them, they’re guaranteed to satisfy your sweet tooth and keep you full until lunch.
What You’ll Need
- 1/2 cup rolled oats
- 1 tablespoon chia seeds (optional, for thickness)
- 1/2 cup unsweetened almond milk (or milk of choice)
- 1/4 cup plain Greek yogurt (or plant-based yogurt)
- 1 tablespoon unsweetened cocoa powder
- 1–2 teaspoons maple syrup (to taste)
- 1/4 teaspoon vanilla extract
- 2–3 chocolate sandwich cookies (such as Oreos), crushed
- Pinch of sea salt
Optional Add-ins:
- 1 scoop vanilla or chocolate protein powder
- Extra Greek yogurt for layering
- Crushed cookies or mini chocolate chips for topping
Pro Tips
- Crush cookies just before mixing – This keeps the cookie pieces from getting too soggy overnight.
- Add protein powder for a boost – Vanilla or chocolate blends seamlessly and makes the oats more filling.
- Sweeten to taste – Depending on your cookies and protein powder, you may want more or less maple syrup.
- Use Greek yogurt for richness – It adds a creamy, “frosting” texture that mimics the Oreo filling.
- Layer your oats – For a visual wow factor (especially if serving kids), layer oats and crushed Oreos parfait-style in a clear jar.
Tools You’ll Need
- Mason jar or glass container with lid
- Measuring cups and spoons
- Spoon or small spatula for stirring
- Small bowl for mixing
- Refrigerator space for chilling
Substitutions and Variations
- Dairy-free? Use plant-based milk and coconut or almond yogurt.
- Gluten-free? Use certified gluten-free oats and gluten-free sandwich cookies.
- No chia seeds? Skip them, or replace with 1 tablespoon flaxseed meal.
- Want it richer? Add a tablespoon of nut butter or a splash of coconut cream.
- Make it nut-free? Use oat milk and a nut-free yogurt alternative.
Make-Ahead Tips
These overnight oats are a meal prep dream. Make a few jars at once and store in the fridge for up to 5 days. Just wait to add extra toppings (like crushed cookies) until just before serving to keep them crunchy.
They’re great for busy mornings, school lunches, or even a post-dinner snack that feels indulgent but is actually balanced and nourishing.
How to Make Oreo Overnight Oats
1. Mix the Dry Ingredients
In a mason jar or bowl, combine oats, chia seeds, cocoa powder, and a pinch of salt.
2. Stir in the Wet Ingredients
Add almond milk, Greek yogurt, maple syrup, and vanilla. Stir until completely combined and creamy.
3. Fold in Crushed Cookies
Gently fold in 1–2 crushed cookies, saving a few pieces for topping.
4. Cover and Chill
Seal the jar and refrigerate for at least 4 hours or overnight.
5. Serve and Top
In the morning, give the oats a good stir. Top with extra crushed cookies, a drizzle of yogurt, or chocolate chips.
Leftovers and Storage
Store any leftovers in a sealed container in the fridge for up to 5 days. Stir before eating and add a splash of milk if the oats have thickened too much.
For best results, wait to add crunchy toppings until right before serving to preserve texture.
