So.. what are overnight oats?

Overnight oats are a delicious breakfast made with a mix of oats, milk, flavors and mix-in’s of choice, and are eating after being chilled overnight. The best part is you can add all sorts of different things to them to switch up the flavors – spices like cinnamon, peanut butter or chocolate for something more indulgent, or berries/dried fruit.

To make overnight oats simply add all of the ingredients into a mason jar, give it a mix, then let it chill overnight in the fridge. The oats soak up all the liquid and flavors and soften up, so they’re ready to go in the morning!

If you’re obsessed with oats for breakfast, try my strawberries & cream chia overnight oats! Or if chia pudding is more your jam, you will LOVE my blueberry chia pudding with lemon cashew cream or my chia pudding with peanut butter magic shell.

Ingredients & substitutions

Full measurements & instructions will be in the recipe card below!

  • Oats: You can use old-fashioned rolled oats or quick oats. I personally like the texture of quick oats better, but feel free to use a mix of both or whichever you prefer! I recommend using organic oats, as oats are heavily sprayed with the harmful pesticide Glyphosate.
  • Almond butter: You can also use cashew butter or sunflower butter for a nut-free option. I’d recommend steering away from peanut butter as that’ll change the flavor of the recipe!
  • Raisins: You can also use chopped dates!
  • Coconut yogurt or greek yogurt: This adds an amazing creaminess to the recipe!
  • Vanilla protein powder: Adding protein powder is optional, but I highly recommend it for blood sugar balance and satiation. Protein is super important, especially in the morning, and will keep you full and satisfied all morning!
  • Sweetener: For a real cookie flavor, i’d recommend using coconut sugar or golden monk fruit sweetener, although maple syrup and honey are also great!
  • Milk: You can use whatever you have on hand – I used cashew milk!
  • Pantry staples: Vanilla extract, cinnamon, sea salt

Making oatmeal cookie dough overnight oats without protein powder

You can omit the protein powder, however I recommend adding a source of protein to the oats for blood sugar balance and satiation! If you don’t want to use protein powder, you can use a high-protein milk option or even stir in a few tablespoons of hemp seeds for some plant-based protein!

Protein recommendations: I have two that I absolutely love. Macro Mike protein powders taste like dessert and truly make any recipe taste INCREDIBLE. They add a sweetness and flavor to the recipe that is unmatched. I love using their salted caramel flavor in this recipe! You can use my code “amb-dani” for a discount on any order!

I also love Truvani. Their formulations are created with very simple ingredients and taste great! I use their vanilla flavor in this recipe! You can use my code “DANI” for a discount on any order!

Equipment:

Steps

  • Step one: In a bowl, combine all of the ingredients, mixing well until there are no clumps.
  • Step two: Add the oat mixture to your jar or bowl, cover, and place in the fridge overnight or at least 4-5 hours. Be sure to give the oats enough soaking time as this is what softens them and creates the best texture. If you’d like a lighter/thinner consistency, add an extra 3-4 tablespoons of milk.
  • Step three: When ready to eat, I like to top my overnight oats with coconut yogurt (or greek yogurt) and a few of my leftover protein cookie dough balls (this is totally optional, but delicious!).

FAQ’s, Tips, & Tricks

  • Are overnight oats gluten free? Those who are strictly gluten-free often avoid oats. However, the brand One Degree Organics have certified gluten free sprouted oats that are great (and easier on digestion).
  • Which milk works best? These overnight oats can be made with coconut milk, almond milk, or any other plant-based option. Dairy milk also works for those who aren’t dairy-free. I like to use full-fat canned coconut milk. Sometimes i’ll use solely that or mix it with another plant-based milk (half canned coconut milk, half cashew milk, for example).
  • Be sure to let them soak overnight (or at least 5-6 hours): The longer they soak, the softer the oats become. This is the goal!
  • How to store overnight oats: I like to store overnight oats in individual containers. There are a few options! Mason jars work great or even these containers with spoons!
  • Can overnight oats be eaten warm? They are best chilled the next morning, however you can heat them and enjoy! Simply add a little milk to the container and heat in the microwave or pour the oats into a small saucepan with a little milk and warm that way. Add more milk, as needed.
  • Can you freeze overnight oats? I wouldn’t recommend it. These are so quick and easy to make fresh!
  • Which type of oats work best for overnight oats? Quick oats or old-fashion rolled oats work best. I personally prefer a mix of the two together (doing 1/2 and 1/2). Do not use steel cut oats as these will not turn out!

how to store oatmeal cookie dough overnight oats

Store overnight oats in the fridge for at least 4-5 hours-overnight. This allows the oats to soak up the liquid and become softer. They will last 4-5 days in the fridge.

  1. This sounds delicious! Do you prefer using almond or cashew butter? Just wondering if one tastes better than the other in this recipe. Thanks!

    1. Hi Marissa! Thank you! I prefer almond butter, just because I love the flavor! Cashew butter is more neutral, but works sooo well in cookie dough flavored things because of that. So it really is up to you! Both are equally delicious.
