What You Need to Make this Recipe

  • Oatmeal: Use old-fashioned oats to make Oreo Overnight Oats. Steel-cut oats don’t absorb enough liquid, and instant oats turn out mushy.
  • Chia Seeds: Chia seeds provide a silky texture while adding protein to the otherwise dessert-like overnight oats; they’re also a great source of fiber and healthy fat.
  • Vanilla: Sweeten the oats with vanilla extract.
  • Milk: You can use water or milk, like dairy, oat, soy, almond, or coconut milk- like we do for Overnight Oats with Coconut Milk. I prefer regular milk for this recipe because it tastes like dunking Oreos in a glass of milk.
  • Oreo Cookies: Oreo cookies sweeten the oatmeal without any additions.
  • Toppings: The toppings are optional, but crumbled Oreo cookies are dessert in a cup.

Additions and Substitutions

  • Dairy – Add Greek yogurt or cottage cheese to increase the protein and creaminess of the overnight oats.
  • Fruit – Top Oreo Overnight Oats with fresh fruit like strawberries, raspberries, or banana slices.
  • Nuts – Finish the oats with chopped almonds, pecans, or walnuts.
  • Nut Butter – I love melting almond butter and drizzling it over the top, but you can use any seed or nut butter.
  • Sweetener – Replace the brown sugar in the recipe with honey, agave, monk fruit, or stevia. For a protein boost, sweeten the oats with your favorite protein powder; our Protein Overnight Oats is an example of how we use it.

Expert Tips

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

  • Store overnight oats in a jar with room to spare since the oatmeal expands as it rehydrates, and so will any mix-ins you add.
  • I find a 1:1 ratio of one part old-fashioned oats and one part milk the best unless you add chia seeds. Use less liquid if you want thicker oatmeal and more if you like it runny.
  • Despite the name overnight oats, they only need to soak for 2-3 hours before you can enjoy them. However, the longer you soak the oats, the softer they will become.
  • 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.

Frequently Asked Questions

Do you eat overnight oats warm or cold?

Serve overnight oats chilled straight from the fridge for a convenient, no-cook breakfast that doesn’t need to be heated. However, if you crave something warm, microwave the oats for 30 seconds to a minute before adding the toppings.

What is the ratio of oats to liquid for overnight oats?

It’s a matter of preference. I find a 1:1 ratio of one part old-fashioned oats and one part milk for the best result, but I add more if I include chia seeds since they absorb more liquid. Use less milk if you want thicker oatmeal and more if you like it runny.

Are overnight oats unhealthy?

Absolutely! Finding a balance between indulgent and healthy ingredients is key to enjoying a well-rounded diet. Take these oats, for instance. While they contain sugar and carbohydrates from crushed cookies, they also include protein and fiber- a great way to start your morning. While I don’t recommend eating Oreo Overnight Oats every day- they are a delicious breakfast treat.
