If you’ve never tried overnight oats you’re in for a real treat! And these cookie dough overnight oats are beyond delicious! Overnight oats are a no-cook method of making oatmeal. Instead of cooking the oats on the stovetop or in the microwave, you soak the raw oats with milk and a few other ingredients. As the oats soak, they will absorb the liquid and become soft enough to eat uncooked. They need a bit of time to fully absorb the liquid (at least 3 hours) and work great to soak all night long; hence the name overnight oats!

In the morning, you have a ready-to-eat, delicious, creamy bowl (or jar) of oatmeal. You can eat the overnight oats cold, straight out of the refrigerator, or pop them in the microwave and warm them up a bit. The consistency is similar to porridge or pudding. It makes for a hearty and convenient breakfast that has a more thick and creamy texture than cooked oatmeal.

Ingredients needed for this overnight oatmeal recipe

Cookie dough overnight oats are packed with good-for-you ingredients. They also make for a hearty, satisfying breakfast with a good balance of fat, protein, and carbs. Here’s everything you’ll need to make them:

  • Rolled oats: We’re using rolled oats to keep a creamy texture. Be sure to use certified gluten-free oats, if you need to keep the overnight oats gluten-free.
  • Chia seeds: Adds healthy fats, fiber, and protein. Plus they thicken up the overnight oats for a wonderful texture.
  • Mini chocolate chips: Either dark or milk chocolate chips are great for that classic cookie dough flavor.
  • Protein powder: For a boost of extra filling protein! Use either whey or plant-based protein powder for this recipe. If you are vegan, then you will want to use your favorite vegan protein powder.
  • Kosher salt: To intensify flavors and balance all the ingredients.
  • Nut butter: Use either almond butter or peanut butter to make these oats super creamy, and filling, and add a wonderful nutty flavor.
  • Maple syrup: To naturally sweeten the oatmeal.
  • Vanilla extract: Vanilla adds a nice, sweet flavor to the recipe. You can sub with almond extract for a nutty taste.
  • Milk: Feel free to use any milk you’d like. We typically use almond milk or cashew milk for a low-calorie option.

Recipe notes and tips

Here are some tips for perfect overnight oats every time!

  • Vegan + dairy free: This recipe is super easy to make vegan and dairy free! Just be sure to use non-dairy milk and dairy-free chocolate chips.
  • Nut free: Can’t have nuts? You can simply leave out the nut butter or use sunflower seed butter, which is typically allergy friendly.
  • Warm them up: Not a fan of cold oatmeal? Overnight oats are actually great warmed-up, too! Simply warm them in a bowl in the microwave for 30 seconds to a minute or two, depending on how warm you like them. Once heated, give them a good stir, and feel free to add a bit more milk, if you’d like.

    Delicious! Dessert for breakfast. I used small dark chocolate chips. Next time I will omit the maple syrup as it was too sweet for me.

  2. How does one successfully divide this up into equal jars after its mixed? We use dairy milk so maybe that’s the difference as it’s thinner?!

    1. Hi there. You can either make them individually in each jar or keep them in a bowl and let them soak for a few hours so it thickens up a bit and it will be easier to do so equally.

  3. It sounds good, but it’s definitely not gluten free or vegan. Chocolate chips are made from milk fat and most protein powders are whey based and many have gluten added for creating a smooth texture. I don’t worry about those issues so I plan to try the recipe. If it a health concern for you, do your research.

    1. Hi Joy. There are dairy-free chocolate chips and plant-based protein powder. It can be made vegan and you may also use gluten-free rolled oats.
