What’s A Keto Shamrock Shake?

A Keto Shamrock Shake is like your classic Shamrock shake but without the carbs.

The classic St Patrick drink is made with vanilla ice cream, whipped cream, and other sugar-loaded ingredients, it’s therefore not keto-friendly at all.

This avocado spinach smoothie with peppermint extract is the answer. And if you wonder if it tastes like avocado, don’t worry, I promise you, nobody will guess it!

It tastes exactly like the Shamrock Shake recipe you have been craving for. Just think about it: a creamy, smooth, and frothy minty vanilla shake topped with unsweetened whipped cream. Yum!

How To Make Keto Shamrock Shake

Now, let’s see how ridiculously easy you can make this keto avocado smoothie, also known as Keto Shamrock Shake, this 17th of March.

Key Ingredients

  • Avocado – make sure you are using a soft, ripe avocado with no black spot on the skin to avoid bitterness. Avocado is one of the keto-friendly vegetables due to its high amount of fiber.
  • Unsweetened vanilla almond milk – or unsweetened almond milk.
  • Canned coconut cream – this is a keto vegan Shamrock Shake, so I am using dairy-free coconut cream. However, heavy cream will work too!
  • Spinach – yes, there is an extra green hidden in this keto shake. I should probably rename this recipe avocado spinach smoothie then. But rest assured, the recipe works without spinach if you are not sure about that. This only adds a boost of green color and can totally be skipped.
  • Peppermint extract – for the classic minty flavor of a real Shamrock Shake recipe.
  • Erythritol for sugar-free sweetness; use my keto sweetener converter if you want to use a different keto sweetener.
  • Ice cubes – this is what makes the difference between an avocado spinach smoothie and a healthy avocado milkshake! The ice cubes combined with ripe avocado mimic the ice cream usually used in milkshakes. Now, you know why this recipe is called healthy Shamrock Shake, right? This said, if you are more into a smoothie texture, less frothy, simply omit the ice cubes!

This keto vegan Shamrock Shake recipe makes a delicious, refreshing breakfast drink or snack. In fact, it contains many nutrients.

You’ll probably be surprised, but this whole recipe contains only 3.8 grams of net carbs. But, also 53 grams of healthy fat and 6.9 grams of protein to feel full.

So if you are craving a sweet luscious smoothie today, St Patrick or not, this avocado milkshake will make you happy.


A classic shamrock shake recipe includes whipped cream on top and a glazed cherry. Obviously, those two are sugar-loaded and not keto-friendly.

My option is to use unsweetened whipped coconut cream using the cream from the top of a can of coconut cream. Otherwise, unsweetened whipped cream works if you eat dairy.

Finally, the cherry on top is replaced by raspberry, a low sugar keto-friendly fruit with a touch of red color.

Bonus, if you have lovely shake glasses like this one below, go for it! It will look even closer to a real shamrock shake!
