Who doesn't want cookie dough for breakfast? Well, these Cookie Dough Overnight Oats, you can have all of the flavor, but nutritious and much lighter. Oats mixed with milk, yogurt and nut butter as the base, sweetened and then chia seeds and optional protein powder added for a protein boost. A sweet breakfast you will want to make time and time again.

5 minutes is all you need to prepare these cookie dough oats. Just mix everything together and put it in the fridge for at least 4 hours, but preferably overnight oats. They are so easy to adapt with optional mix-ins too and are a great addition to your weekly meal prep. If you are not usually a fan of oats for breakfast, you need to try this!

Breakfast time is always chaos in our house, so knowing that we have these cookie dough overnight oats ready in the fridge can some times be the difference between eating breakfast and skipping it - we can even eat it on the go. Our kids love them too (we just leave out the protein powder if making this for them).

Protein packed and full of fibre, these chocolate chip cookie dough overnight oats taste like breakfast for dessert. The best texture, all the flavor of cookie dough, but super nutritious, filling and SO easy to make.

Ingredients and Substitutions

All the ingredients needed to make this recipe, each with a text overlay label.

A full ingredients list, along with US Customary and Metric measurements, can be found in the recipe card at the end of this post.

  • Oats - We used rolled oats for this recipe, which will take overnight to absorb the liquid and soften but it gives more of a chewier cookie texture. You can use quick cook oats too, which would be ready quicker.
  • Protein powder - This is optional (and we leave it out when making it for the kids), but it's an easy way to give your breakfast a protein boost. You can also use flavored protein powder like chocolate or vanilla for added flavor. We like this Vanilla Protein Powder, as it has minimal ingredients.
  • Cinnamon - Adds a lovely warmth to the overnight oats. You could use ground ginger or nutmeg instead.
  • Chia seeds - Another way to add some protein. It also adds a really nice texture as they expand when mixed with liquid. You could use flaxseeds instead.
  • Vanilla - Make sure to use extract rather than vanilla essence.
  • Maple syrup - This is how we have sweetened it and kept it refined sugar free. Another liquids sweetener like honey would work too. If you wanted a more authentic cookie dough flavor, then use brown sugar.
  • Chocolate chips - It's not cookie dough without it! We use Refined Sugar Free Dark Chocolate Chips for these chocolate chip overnight oats.
  • Nut butter - You can use whatever your favorite nut butter is. Peanut butter, almond butter or cashew butter all work. You could use sunflower seed butter to keep it nut free, but it wouldn't give that same cookie dough flavor.
  • Milk - Any milk will work. Use a plant based milk to keep it vegan.
  • Yogurt - We used 0% fat Greek yogurt which also adds some extra protein, but still keeps it light.

Variations

A breakfast that tastes THIS good shouldn't be this easy - but it is! The best thing is, it's so easy to adapt cookie dough overnight oats, so you can adjust them to suit your own tastes, or what you have that needs using up.

Chocolate - You could use cacao nibs instead of chocolate chips to make this even more nutritious. You could also add some cocoa/cacao powder along with the oats for an extra chocolatey flavor.

Mix-ins - Much like cookies, there are so many different things you can add in. Dried fruit like raisins, cranberries and cherries work well. As do seeds, coconut or chopped nuts.

Serving Suggestions

This is a delicious and nutritious breakfast as it is. However, we love to load some extra toppings on top. This does change the nutritional information, but it's totally worth it.

To keep it simple, you could just add some extra chocolate chips and nut butter on top. For added crunch, you can't go wrong with some granola. Have you tried our Air Fryer Granola?

You can add fruit like berries, banana slices or even something like caramelized pineapple. Or, why not try our Superfood Sprinkle Mix?

Extra Tips

  • To really give it that cookie dough flavor, add a little almond extract too.
  • Make sure to use certified gluten free oats to make this recipe gluten free.
  • Everyone has different preferences when it comes to the texture of overnight oats. So you can make it runnier or thicker by adjusting the amount of milk and yogurt used.
  • Why not add a pinch of salt to bring out the sweetness of the other ingredients?

Frequently Asked Questions

How to store cookie dough overnight oats

Stored in airtight containers, these will keep for up to 5 days in the fridge. They are great for weekly meal prep.

Can I use quick cook oats?

Yes, you can, and they will be ready quicker and won't need to go in the fridge overnight. However, you won't get the same chewy texture that you would get with rolled oats.
