How many calories are in this cookie dough smoothie recipe?

Per smoothie, serving is about 500 calories (499.7Kcal).

And trust me I know this by fast, as I nearly joined the anonymous group for Cookie Dough addicts…

Until I managed to create this healthier version… Now I found my new addiction.

When is the best time to make this Healthy Cookie Dough Smoothie Bowl?

It’s a great meal-replacement smoothie, as it is super filling, due to the oats and the bananas.

A meal replacement should be high in nutrition, protein, fibre, fat and a good amount of calories. This smoothie fills all of these criteria:

  • Calories: 499.9
  • Fat: 33%
  • Fibre: 43%
  • Protein: 31%

Omg, like the best thing ever.

I think because it’s quite high in vanilla bean paste and the (VERY RIPE) bananas.

Cookie Dough Smoothie Bowl Ingredients

Must-have Ingredients


Oats build the base, together with this delicious Cookie Dough Smoothie Recipe. Oats are super filling and that’s why it’s a great base for a breakfast smoothie recipe. Also, they are high in plant-based protein, did you know that?

On top of that, it is highly beneficial because it’s good for your gut, helps against constipation, can lower the chances of colon cancer, and lowers blood sugar levels. It can even help with weight loss, despite you might not believe me. But because it is so filling, you will less likely snack too much and even eat less at your next meal.


You can use many different ones, ideally an unsweetened one, for health reasons: Any nut milk is fine. Even soy milk, as it’s rich in nutrition is good.


One of the key ingredients of this recipe is a high-quality vanilla bean paste. It makes all the difference in the world if you have a high-quality one, (where you see the black little dots, from the vanilla flower) compared to using a cheaper one. Especially many vanillas exact, are thinned out and have a faded taste.

Do you know the benefits of vanilla bean paste?

It is rich in rich in antioxidants, and with that fighting chronic diseases and reduces the risk of cancer. Vanilla bean paste (extract) is anti-inflammatory and is good for your brain health. It can also reduce sugar intake, which you’ll notice in this recipe for example. Because there was no need to add any more as it tastes already sweet in itself.


The protein powder makes this Healthy Cookie Dough Smoothie more filling. It is also good for weight loss and helps to build muscle and repairs tissue. But another reason is why I love adding protein powders to smoothies (and to greek yoghurts for a midnight snack) because it adds in flavour. At least if you have a good one.


You have to add cinnamon for flavour! 

Are you also a little cinnamon obsessed?

That’s fine. While it can help with your gut health, it also manages your blood pressure, lowers your blood sugar and reduces the risk of type-2 diabetes.

And most importantly cinnamon is known to be anti-viral, anti-bacterial and also anti-fungal!

It’s anti-everything!!!

Cinnamon also can help you to protect your brain against the ageing process, and against Alzheimer’s disease, which is always a frightening thought.  Don’t you think?

At least I am worrying if ever getting it, or that my loved ones 


These are MUCH healthier than chocolate chips, but you can use them either. They aren’t as sweet as chocolate chips, but richer. 

But these are much less processed. And processed foods are seriously bad for your health. Unless you use dark chocolate, which the cancer organisations recommend you consume, rather than other types of chocolate. But only in smaller amounts.

Cacao nibs are also high in magnesium and manganese. These crispy, and crunchy little things are also anti-inflammatory that is extremely high in antioxidants.

They even protect you against diabetes, heart diseases and as mentioned cancer.


Be careful though, if you are pregnant, breastfeeding or are sensitive to allergic to chocolate or dietary nickel, as cacao nibs can cause an effect.


 Adding sweetness, making the smoothie thick, creamy, and cold. 

Plus they add fibre, and nutrients and may help to control your blood sugar levels. They are great for your digestive systems (since I’ve eaten smoothies daily, I have NO bloating issues anymore!) and high in antioxidants (the things that fight diseases).


These super-rich nuts, add a buttery, creamy taste and structure, which is ideal for this cookie dough smoothie bowl recipe. But you can also exchange it with cashews, peanuts, almonds or any other nuts.

I love adding macadamia nuts into smoothies because they are also great to improve your gut, that’s because they are high in fibre, they ensure that your blood sugar doesn’t spike up and stays consistent, and they are great for your heart.

All ingredients are a must for this recipe, but you can replace the milk, and nuts with any of your favourites.

Optional Ingredients


Because cauliflowers add thickness and creaminess to this smoothie bowl. Besides you can sneak in additional nutritions, fibre, and antioxidants. It’s also good for weight loss. On top of that cauliflower is high in Choline, Sulforaphane (which cancels out free radicals).

My Secret Recipe Tips

1. BLEND THE OATS: Oat Flour

My tip is, that you add the Old fashioned oats first into the blender.

And then you blend them for about 30-60 seconds until they become finely blended oat flour. This makes the difference and changes the whole texture of this smoothie.

Then you continue adding the milk and the other ingredients. This way you end up with a much smoother and creamier, butter-like texture.

 Because the first time I tried this recipe, the oats didn’t fully blend, and although it was still incredibly tasty, I wasn’t that much impressed by the texture. And then I thought, HEY, why not blend the oats first. :0

2. MAKE IT THICK: Add cauliflower

This is another secret tip, which is adding also creaminess to the smoothie, without having to add smother tons of calories to this cookie dough smoothie. This wonder veggie is super healthy. Because it is low carb, low-calorie, high fibre, and extremely nutritious.
You can add fit literally to any smoothie, without changing the taste, and colour, making it healthier and thicker and creamier. What a game-changer, right?

Q&A Cookie Dough Smoothie

Is it healthy to put oats in smoothies?

Yes, adding oats to smoothies is a great way to add nutrition and fibre to your smoothie. They are very filling and promote weight loss. 
On top of that, they can reduce the risk of heart-related diseases and diabetes. Oats are great for your gut and intestinal health.
So, feel free to add oats to your healthy breakfast smoothies or meal replacement smoothies.

Which oats are best for a cookie dough smoothie recipe?

I have tried this recipe so far only with Old-fashioned oats.
It works very well, with the 2 variations. Either just drop all ingredients into the blender to make the Cookie Dough Smoothie Recipe, or firstly add the Old-Fashioned oats, blending them and making oat flour. And then adding the other ingredients. 
But I can imagine, that you can also use quick-cooking oats or steel-cut oats (certified gluten-free oats work too!)

Can I make a smoothie and leave it in the fridge overnight?

Yes, you certainly can make a smoothie and leave it overnight in your fridge. But you will want to cover it up. My secret tip is to store your smoothie overnight, to pour it into a thermal cup. That often still keeps it kind of in a semi-thick and cool temperature, but better than if you would just store it in a glass.
Smoothies in a fridge are good to keep for up to 24 hours, or you can freeze them.

Can I use steel-cut oats, to make oat flour?

Yes, you totally can. It depends, if you are using a blender, or if you are using a food processor. Because I had trouble once using my food processor, and getting it very fine. But using a blender, especially a high-speed blender to make oat flour works with steel-cut oats.
Give it a go! 
 Note: In this recipe, you don’t need to have the flour perfectly fine anyway, so even if the flower has still some smaller.

What makes a smoothie thicker?

There are lots of different ways how you make a smoothie thicker.
Oats are one way. You can see in the picture how thick and creamy this smoothie is.
Use very little liquid to make a smoothie super thick.

Bananas help to thicken smoothies. You can use thicker milk, like oat milk, instead of water or almond milk, or you can even freeze your milk into ice, like coconut milk.
Another great way to thicken up smoothies is by adding chia seeds because they are turning into gel-like creamy things when they combine with water or milk.

Also, you shouldn’t over-blend your smoothie to make it thick, otherwise, the blender heats up, and it becomes thinner. And the key for any thick smoothie is that all ingredients get evenly blended. You do that by pushing down the fruits and ingredients constantly with your temper if you have one. They come with a Vitamix for example. In another blender, you need to shake in-between very well. You can also turn it off and stir manually.
Yes, it is hard work, to make a thick and creamy smoothie bowl.

RELATED16 SECRETS – How to make a smoothie thicker

Which type of oats is the healthiest?

All types of oats are very healthy, as they are high in protein, nutrition and vitamins. But steel-cut oats are a little less processed.
The unhealthiest oatmeals are the one that contains added sugars. Many pre-packed and ready packs have added brown sugar, instant maple or other sweeteners added which are not a healthy choice.
If you consume them more often, your risk of diabetes, obesity or heart risk would be increased.

What is the difference between the oat types?

Steel-cut oats have a less processed, and chewy and nutty texture, but take longer to prepare.
While rolled and instant oats taste milder and softer but takes only a few minutes to cook and prepare.
Both types contain plenty of nutrients, protein and vitamins and can be added to smoothies, baking dishes and your breakfast.

Is oat (flour) really gluten-free?

Make sure, that your oat flour is really gluten-free, you want to get certified-free oats, and then blend them to make flour out of them.
You can also buy certified gluten-free oat flour directly er at the store. But I prefer buying the oats, and then making the flour yourself because while you are making the smoothie it just takes like 30-60 seconds longer.

But the key is to buy CERTIFIED gluten-free. Otherwise, the oats could be cross-contaminated, meaning, the factories could produce other products where gluten is involved and small particles might end up in the package.

Is this Cookie Dough Smoothie really Vegan?

Yes, it is! As with most smoothie recipes, the ingredients are not 100% fixed.
Like this Cookie though smoothie recipe tastes good with plenty of different milk types. Any nutty type of milk takes in credible good, and they are all vegan. Then make sure to choose a vegan protein powder.
