This mixed berry protein smoothie with chocolate is definitely one of my favorite smoothies, and I’m very excited that you’ll soon find out why!

It has an incredible berry and chocolate flavor that makes it taste like a dessert, gets hidden fruit in in the form of avocado, and is super versatile if you don’t have the exact ingredients on hand.

Oh, and it packs in a whole bunch of protein as well, making it class as a protein shake (without the boring taste!). Great stuff!

Why you need this mixed berry protein smoothie NOW

It tastes like a berry and chocolate smoothie, not a protein shake

Thankfully, this protein berry smoothie does not taste like protein powder.

As you may or may not know, protein powder mixed with water (the default way to take it), is, more often than not, a pretty horrible experience.

That’s why I like to mix my protein powder in to smoothies!

This protein shake’s flavor leans so far towards berries and chocolate, you would never know there is even protein powder in it.

Of course, it does depend what chocolate protein powder you use, as not all are created equal.

I like to use Optimum Nutrition Gold Standard 100% Whey Double Rich Chocolate protein powder, as it’s a favorite among gym-goers and also tastes great.

The other great thing about this frozen fruit protein smoothie is that it is packed full of nutrients.

You have 26.2g of protein (helped by the protein powder), a bunch of magnesium and potassium from the avocado, cultures in the yogurt, and all the healthy vitamins in the frozen fruit.

Sure, it may taste like a dessert, but you can relax happy knowing that this mixed berry protein smoothie is actually good for you (unlike that chocolate cake you could have instead!)!

This is a Keto-friendly mixed berry protein shake

Checking in at 14.4g of net carbs, this still falls within what I would call Keto-friendly.

I regularly have this smoothie and still manage to keep within 25g net carbs per day, so even if you are keeping your carb count pretty low you are still good with this.

If you find that the net carb count is slightly too high for your liking, the best thing to do is swap some of the mixed berries for some Stevia.

Be SURE to use a very dark chocolate with a low carb count.

I personally use Lindt Excellence 90% Dark Chocolate. It’s very low carb (1.4g per 10g), tastes great, and isn’t too expensive, considering how far it goes. (Note: its ingredients vary slightly around the world, which does affect the nutritional values, but not enough to worry about too much.)

This is a versatile protein berry smoothie

As detailed below, this is a very versatile smoothie.

The deep flavor from the dark chocolate and the mixed berries gives an incredible flavor profile, but if you don’t have or aren’t a fan of certain aspects of the smoothie, you can simply swap them out without too much hassle.

This is the kind of recipe that you can go to time and time again with slightly different ingredients in your fridge and not worry too much. Great stuff!

Things to look out for and swaps

It goes without saying but, as ever, substitute yogurt, protein powder and chocolate those suitable for your diet and allergies.

This is a very versatile recipe. If you don’t like or have mixed berries, you can add any red berries of your choice.

It’s a mixed berry protein smoothie! So mix it up!

If you are not a fan of dark chocolate (and are not worried about the carb impact!), try substituting the dark chocolate for a lighter variety.

If you are trying to go super low carb with this berry protein shake, you could swap out some of the mixed berries for 1.4 teaspoon of Stevia, bringing your net carb count down.

If you are keeping an eye on carbs, be sure to choose a yogurt with a low amount of sugar – manufacturers often fill yogurts with sugar to make them taste sweeter, and this will naturally impact the amount of carbohydrates in the recipe.

If you are using frozen fruit, be sure to blend it first in to a kind of crushed ice, otherwise it can struggle to mix in to the recipe.

Finally, if you don’t have chocolate protein powder, strawberry or plain will work well, as the dark chocolate flavor will still come through.

Supplements you can add to your protein berry shake
