Oreo Overnight Oats

Cookies for breakfast? Why not! The delicious cookies and cream-inspired Oreo overnight oats combine creamy rolled oats, chia seeds, crumbly Oreo cookies, and a splash of milk for a quick grab-and-go treat! 

Key Ingredients

• Oreo Cookies: Oreo cookies sweeten the oats without additional sweeteners, but if you prefer something more sweet, feel free to add a little honey, agave syrup, maple syrup, or a sugar-free option like monk fruit. Another way to sweeten the oats and get in a little extra protein is to combine the milk with protein powder before mixing it with the oats, like I do for protein overnight oats.
• Oatmeal: Use old-fashioned rolled oats to make the Oreo overnight oats for the best consistency. Steel-cut oats don’t absorb enough liquid and come out chewy; instant oats end up mushy.
• Chia Seeds: Chia seeds give the oats a silky texture and a little protein.
• Vanilla Extract: Add a splash of vanilla extract to balance the flavor.
• Milk: Use water or your favorite milk to prepare the old-fashioned oats. Regular milk is my go-to for this recipe because it tastes just like dunking Oreos into a glass of milk. Try unsweetened almond milk, oat milk, soy milk, or coconut milk, as I do for overnight oats with coconut milk, to find what you like.

Additions and Substitutions

• Increase the protein. You can make the overnight oats more filling by stirring in some Greek yogurt or cottage cheese.
• Experiment with toppings. Oreo crumbles are my favorite way to enjoy the overnight oats once they are ready. Get creative, and top them with fresh fruit like sliced strawberries, raspberries, or bananas. Or finish with nuts—chopped almonds, pecans, or walnuts—provide a nice crunch to complement the creamy oats. You can also melt your favorite nut or seed butter to drizzle over the top.

Expert Tips

For the best Oreo Overnight Oats, follow these helpful tips.

• Find a ratio that works. A 1:1 ratio of old-fashioned rolled oats and one-part milk gives me the best results. However, I adjust the liquid if I add a mix-in, like chia seeds and cookies, which I know will absorb more liquid.
• Give the oats extra room. Use a glass jar or container with extra space—the oats, chia seeds, and cookies will expand as they soak up the liquid.
• Do you have to soak the oats overnight? Despite the name overnight oats, they only need to soak for 2-3 hours before they’re ready to eat—the longer the oats soak, the softer they become.
• Stir before you serve. Give the mixture a good stir before adding toppings and digging in. If the oats seem dry after sitting in the fridge, add another splash of milk.

Serving Suggestions

All you need to make Oreo overnight oats is rolled oats, chia seeds, milk, and crumbly, delicious Oreo cookies. Serve them chilled straight from the fridge for a convenient, no-cook breakfast. But, if you want a warm bowl of oats, heat them in 30-second increments and stir them before adding your toppings.

What To Do With Leftovers

• Refrigerate: Oreo overnight oats stay fresh in the fridge for five days– perfect for weekly meal prep! Store them in the airtight container or glass jar you make them in. If the oats seem dry or sticky after sitting in the fridge, add a splash of milk. Give it a good stir, and they’re ready to enjoy!
