Ingredients and Substitutions

These are the main ingredients and substitutions for this Blended overnight oats recipe. Scroll down to the recipe card at the bottom of this blog post for full ingredient list and instructions.

Organic old fashioned rolled oats work best for this recipe, you don’t have to use organic but they must be old fashioned rolled. I have not tested this recipe with quick oats. To make this recipe gluten-free, use certified gluten-free rolled oats.

I use Ritual protein which is my favorite right now, but you can use any type that you like. I would recommend sticking to plain or vanilla for this recipe!

Ground flax adds fiber which helps keep you full. You can omit if you don’t have it or try adding in some chia seeds in replace.

Almond milk or any type of milk or nut-milk alternative such as cashew milk, coconut milk, hemp milk and so much more.

Cashew butter gives the best cookie dough taste, but you can use any other nut butter in replace. I’d recommend almond butter or peanut butter. To make this recipe nut-free, try using a seed butter like tahini, sunflower seed butter or oat butter.

Vanilla extract adds flavor.

You can’t have cookie dough without chocolate chips! You can use dairy or dairy-free!

For the frosting I did a mixture of coconut base yogurt like the one from Harmless, mixed with melted dark chocolate, my favorite right now is from Hu Kitchen.

How to make

These blended overnight oats are insanely easy to make and they will for sure be your new favorite breakfast.

ONE: In a blender, add in all the ingredients except for the chocolate chips and yogurt.

TWO: Then, blend for 30-60 seconds until smooth and creamy.

THREE: Pour blended oats into a bowl and mix in chocolate chips. Then, place in the fridge for a minimum of 4 hours, or the freezer for 20 minutes to cool.

FOUR: In the meantime, mix together the melted chocolate and yogurt to create the frosting. If your chocolate hardens up due to the yogurt being cold, add it to the microwave for 15 seconds to melt. Then, spread the frosting on top and place back in the fridge or freezer to harden.

FIVE: When ready, remove from the fridge or freezer and enjoy!

Tips and tricks

Blend ingredients on high speed for 30-60 second or until mixture is smooth and creamy. I like to use my Nutribullet since it is a smaller cup and really ensure’s everything is blended together. If you are using a larger blender, you may need to stop to scrape down the sides a few times.

If you’re enjoying that day, throw the blended oats in the freezer for 20 minutes to get them nice and cold, or try adding ice!

Cookie Dough Blended Oats

  • 1/2 cup old fashioned rolled oats.
  • 1 scoop plant-based protein, about 1/4 cup.
  • 1 tbsp ground flax.
  • 1 1/4 cup almond milk.
  • 1 tbsp cashew butter.
  • 1 tsp vanilla.
  • 1 tbsp dark chocolate chips.


  • 3 tbsp coconut yogurt.
  • 1/4 cup dark chocolate chips, melted.




2 servings


  1. In a blender add in oats, protein, ground flax, almond milk, cashew butter, and vanilla extract and blend until smooth and creamy. About 30-60 seconds. 
  2. Pour batter into a bowl and mix in chocolate chips. Cover and refrigerate for a minimum of 4 hours or freeze for 20 minutes to cool. 
  3. When ready, melt chocolate chips and add to coconut yogurt. If your chocolate hardens again because of the cold yogurt, pop it in the microwave for 15 seconds and it should be good to go. 
  4. Then, spread this mixture over your blended oats and smooth out. Either enjoy as is, or place it back into the fridge or freezer to harden once more and enjoy! 


  • If you're enjoying that day, throw the blended oats in the freezer for 20 minutes to get them nice and cold, or try adding ice!
  • Make sure your oats are firm to the touch before adding on the frosting otherwise it will all mix together. If you don't care about aesthetics- it will still taste the same!

I’d love to try these but I’m curious about the calories and nutritional breakdown. Did I miss it somewhere on the site?

hey there! i don’t provide macros because my page is all about enjoying food without the numbers. However, I understand some people need to know for their own reasons so i always encourage to plug the ingredients into a calculator on google to find out! xx

These were pretty good! The frosting was delicious! Frosting would be great with other things too, love that it taste like a treat but still healthy.

How thick should the consistency be? I already had some rolled oats I blended, so I did a little less than 1/2 cup and it looks super thin. Next time I’ll do just unblended oats.

Hi Kate! the consistency should be thick but still liquidy, similar to a pudding. They will firm up once placed in the fridge or freezer. Using rolled oats then blending works best so it’s not super fine. I hope that helps!!

so good, i cooked mine on the stove instead of waiting over night and they are amazing! i made my frosting with a little bit of melted brown sugar mixed with greek yogurt. so yummy!!

Can you use a different type of yogurt for the frosting, would regular 0% fat greek yogurt work?
