Featured Ingredients

mise en place of ingredients to make chocolate chip cookie dough overnight oats
  • Old-Fashioned Oats: I recommend using old-fashioned oats for a classic overnight oats texture. If you do choose steel cut or quick cut oats, know those will impact the absorption amount and time.
  • Flax & Chia Seeds: I like to use a mix of both flax and chia seeds for both nutrition (adds more healthy fats, fiber, and a little protein) and function (helps absorb liquid and creates an ideal creamy overnight oats texture).
  • Greek Yogurt: Greek yogurt adds the best creaminess, plus nutritional benefits, too, like more protein and calcium.
  • Milk of Choice: I use unsweetened almond milk in this recipe and in the nutrition calculations, but use whatever milk you prefer to drink.
  • Chocolate Chips: obviously you need chocolate chips in a chocolate chip cookie dough inspired overnight oats! We love mini chocolate chips for the best ratio of chocolate to overnight oats in each bite, but use what works for you! (I’m also a fan of Lily’s chocolate chips for a no added sugar/ stevia-sweetened variety!)
  • Vanilla Extract: a little bit adds some wholesome vanilla cookie dough vibes!
  • Protein Powder: again, if I’m making this for the kids, I leave the protein powder out (there’s plenty in here for them without it). But my husband and I prefer a little more protein in our breakfasts, so we add a scoop of vanilla protein powder. Collagen peptides work, too. Use (or don’t use) what works for you!

Best Tips to Make Cookie Dough Overnight Oats

  • Use old-fashioned oats – they work best for overnight oats. Using steel cut oats will require more liquid and a longer absorption time, whereas using quick oats may require less liquid and/ or less absorption time.
  • After you stir the overnight oats, let them set on the counter for a few minutes while you put everything away and tidy up. Then, before you refrigerate your oats overnight, give them a second stir. This second stir is KEY for preventing the oats and seeds from settling at the bottom.
  • Always give your oats a stir in the morning before eating to see if you need to add a splash or two of milk to create your desired consistency.
  • Have fun with toppings! We usually keep these cookie dough oats simple with a sprinkle of chocolate chips, but other yummy additions include chopped nuts, sunflower seeds, a drizzle of nut butter, and banana slices.
  • If you’re leaving out the protein powder, start with 1/3 cup milk. I like my overnight oats a little thicker, and the protein powder helps add to that texture. Starting with less milk can help make sure it’s not too loose. You can always add more later!

Recipe Q&A

Are these cookie dough overnight oats gluten-free?

Overnight oats are gluten-free as long as you’re using certified gluten-free oats.

Do you eat these chocolate chip overnight oats hot or cold?

Either! Overnight oats are often consumed cold, but they can easily be warmed.

To warm up your overnight oats, heat them in a microwave-safe container in the microwave for 30 seconds at a time, stirring between each set.

Alternatively, you can reheat in a pot on the stove over medium heat, but you’ll likely need to add a little more liquid here as some liquid is cooked out while reheating.

Are overnight oats healthy?

Overnight oats can absolutely be a part of a healthy, balanced diet. (But remember – it’s not really about individual foods, but more so about your overall eating pattern.)

But overnight oats, like these, are typically a great source of fiber (especially soluble fiber) and often contain protein from certain types of yogurts, milks, and protein powders.

How long do overnight oats last?

Overnight oats last about 3 days in the fridge.

If you need to prepare overnight oats for beyond 3 days, I would suggest prepping the dry ingredients in a mason jar, then sealing it and storing it in your pantry. The night before you need them, simply add the coconut milk and yogurt.

Why are my overnight oats too thick/ thin?

There could be several reasons for absorption issues with your overnight oats. Different protein powders, types of milk, yogurts, and types of oats (i.e. old-fashioned vs. quick) can all alter how much liquid is absorbed.

Plus we all have personal preferences, too, so some (like me!) may prefer overnight oats a little thicker and creamier, and some may prefer them thinner.

Play around with your specific ingredients to see if you need to adjust liquid levels to suit your preferences.
