Ingredients & Substitutions

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.
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: use whatever you prefer to drink! I use an ultra-filtered dairy milk, for an extra protein boost.
Chocolate Chips: 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: I aim for at least 30 grams of protein per meal, and a scoop of protein powder is a convenient way to make that happen. Feel free to also use collagen peptides, or any flavor protein powder that sounds good to you (we love Clean Simple Eats and have made this with their Simply Vanilla, Chocolate Peanut Butter, and Chocolate Brownie Batter).

How to Make Chocolate Chip Overnight Oats

Add everything except chocolate chips to a container and stir.
Let set for 5 minutes, then add mini chocolate chips and stir again.
Refrigerate overnight, or at least 4 hours until set.

Tips & Variations

Use old-fashioned oats – they work best in this recipe. Steel cut and quick oats require different liquid ratios.
Don’t skip the second stir! If your oats and seeds always settle on the bottom, I promise they won’t anymore after the second stir!
Check consistency before eating – I like my overnight oats on the thicker side. If you prefer them runnier, you can stir in another splash or two of milk before eating.
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.

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.
