Cookie Dough Overnight Oats have the sweet, chocolate chip flavor you look for in a cookie dough recipe in filling, oatmeal recipe! These oats are perfect to prep ahead of time and enjoy as a grab-and-go breakfast or snack throughout the week!

What Are Overnight Oats? 

Overnight oats are made by combining whole grain oats with a liquid like almond milk and other tasty ingredients like nut butter, yogurt, jam, or fruit. The oats soak overnight in the liquid, soften, and have the perfect creamy texture, similar to oatmeal, and delicious flavor.

Overnight oats are incredibly versatile and the flavor combinations and toppings are endless. These cookie dough overnight oats have cashew butter, cinnamon, and chocolate chips for a more dessert-inspired breakfast.

Overnight oats are a staple in my meal prep rotation. I eat them almost every week in varying flavors, and I don’t see that changing anytime soon. This cookie dough flavor is incredibly satisfying and such a fun spin on overnight oats. Whenever I’m craving something a little more decadent for breakfast these oats are the obvious choice!

Recipe Ingredients

Oats: for this recipe, we’re using old-fashioned rolled oats. 

Chia seeds: these add a healthy dose of fats and fiber and help create that thick and creamy texture. 

Plain Greek yogurt: I like to use full-fat Greek yogurt to pack this recipe full of protein.

Unsweetened almond milk: this is my liquid of choice to combine the ingredients. 

Vanilla extract: enhances the sweetness and adds that much needed vanilla cookie dough flavor.

Sweetener: you can use your choice of maple syrup or honey. Either will work well! 

Cinnamon: ground cinnamon adds just the right touch. 

Creamy cashew butterthis helps to create that thick, creamy, cookie dough-like taste and texture.

Mini chocolate chips: you can’t have cookie dough without chocolate chips! I prefer to use mini chocolate chips to get delicious chocolate flavor in every bite, but regular-sized chocolate chips will also work. 

Ways to Customize

  • Want your overnight oats to be sweeter? Feel free to add another tablespoon of honey or maple syrup to the recipe, or stir more sweetener in at the end.
  • Don’t love cashew butter? You can use almond butterpeanut butter, or any more neutral nut or seed butter instead. Just keep in mind that the flavor of your oats may change slightly. 
  • Need to keep the recipe dairy-free? You can use your favorite dairy-free Greek yogurt (like coconut milk or almond milk yogurt) and dairy-free chocolate chips in this recipe instead of a dairy yogurt. 
  • Have a favorite cookie? Mix and match different mix-ins to replicate the flavor of your favorite cookie recipe. White chocolate chips, candy pieces, chopped nuts, and dried fruit all make great additions.

Commonly Asked Questions

Can I use quick oats? 

I don’t recommend using quick oats in this recipe. They tend to soak up too much liquid and become soggy in the fridge. 

Why are my overnight oats gummy? 

If your oats are gummy, it’s most often because the wrong types of oats were used or they sat in the fridge too long. I typically don’t store my overnight oats longer than three days to avoid an altered consistency. 

Why don’t you cook overnight oats? 

The process of soaking the oats overnight breaks them down almost as if they were cooked. As a result, they become soft and thick. However, if you prefer warm oats, you can go ahead and microwave them when you’re ready to eat! 

Can I add protein powder? 

Sure! Feel free to incorporate any protein powder you like best, and add more liquid as needed to create a smooth constituency. My go-to High Protein Overnight Oats recipe is a great recipe to start with!

Topping Ideas

These cookie dough overnight oats are absolutely delicious on their own, but you can never go wrong with extra toppings! Here are a few ideas to make your oats even more incredible: 

  • Strawberries
  • Banana slices 
  • Nut butter (more cashew butter, peanut butter, or almond butter would be great)
  • Chia seeds
  • Hemp seeds
  • Shredded or flaked coconut
  • Sliced nuts
  • Fresh fruit jam
  • Chocolate chips or cacao nibs

How to Store the Oats

Store your cookie dough overnight oats in an airtight container in the fridge for 3 to 5 days. Just note that while they will still be good to eat after a few days, the texture of the oats may change as they soak up more liquid.

I like to make a batch to enjoy for two or three days. Then, I make another instead of making enough at once to eat all week long!
