This coffee protein shake recipe makes a delicious start to the day! It’s got coffee (obviously a must!), protein, healthy fat, and fiber. Not to mention, it’s so rich, thick and creamy, it feels like a coffee milkshake! Pure bliss.
To make this keto protein shake, you’ll need just 4 ingredients and about 5 minutes of active prep time… with just a little planning to freeze part of it ahead.
We’re using a base of Atkins Protein Shakes, which make this coffee-flavored low carb protein shake sweet and creamy, while keeping carbs low. With 2g net carbs, 5g fiber, and 15g protein in each shake, they are a nutritious and satisfying meal, snack, or addition to blended drinks like this one. And unlike most pre-made shakes, you won’t find any added sugar in these.
How To Make a Coffee Protein Shake
This coffee protein shake recipe is ready in just 5 minutes, but does take a little planning ahead for best results! (Don’t worry, it’s easy!) Here’s how we make this tasty low carb low sugar protein shake:
- Make coffee cubes. Pour coffee into an ice cube tray and freeze overnight, or until solid.
TIP: If you want to make this last-minute and don’t have time to freeze the coffee, you can also just add (cooled) brewed coffee and add ice cubes. However, it will be much less thick that way compared to freezing the coffee into ice cubes. Use a frozen cubes of strong brewed coffee for rich, coffee flavor.
- Chill coconut cream. While you’re making your coffee cubes, put the whole can of coconut cream into the fridge at the same time. Once you open the can, you can easily skim the thick cream off the top, leaving the coconut water behind.
- Combine your Atkins protein shake ingredients. In a blender, combine frozen coffee cubes, Atkins Protein Rich Shake, coconut cream, and avocado.
FYI: Don’t worry, you won’t taste the avocado in there! But it does add healthy fats and helps thicken the shake.
- Blend. It will be very thick and creamy!
TIP: This comes out very thick, like an ice cream milkshake. If you want it thinner like a smoothie, you can either add more of the (liquid) Atkins Protein Shake to get the consistency you want, OR just wait for it to melt a little after blending. It will get thinner as it melts anyway.
You can serve it plain…
Or with sugar-free whipped cream on top!
Keto Protein Shake FAQs
Can you drink protein shakes on a low carb diet?
Let me start by saying that protein shake recipes vary a ton! Many shakes are made with a base of milk, or fruit, or even juice. These ingredients are obviously not great if you’re following a low carb diet, like most us here are doing.
So before you drink, make sure to choose better-for-you low carb protein shakes! This recipe fits the bill.
Are protein shakes keto?
Similarly to the above answer, many protein shakes are not keto, so it’s important to check the label or ingredients first.
The Atkins Protein Shakes that I’m using here are low carb and have no added sugar. And of course, this coffee protein shake recipe is keto!
Can I mix coffee with a protein shake?
You could mix coffee with a prepared protein shake (like Atkins Protein Shakes!), but the result would be more like a latte than a shake.
If you want a creamy coffee flavored protein shake, this recipe is a huge step up. 😉 Instead of mixing coffee directly with the protein shake, we’re freezing the brewed coffee first, adding some avocado and coconut cream to thicken, and then blending everything together to create a thick and frosty shake.
Can I make this a chocolate coffee protein shake?
Yes, and I like where your head’s at. 🙂 For a chocolate version, you can add 1-2 tablespoons of cocoa powder to your liking, or just use an Atkins Chocolate Delight Protein Shake instead of the vanilla one.
Are these keto friendly protein shakes sweet?
This makes a mildly sweet iced coffee protein shake. If you want it sweeter, feel free to add an Atkins friendly sweetener that dissolves well, such as allulose.
Low Carb Protein Shake Storage Instructions
Can you make an iced coffee protein shake ahead?
I recommend prepping the ingredients ahead so they are ready to go, but this vanilla coffee protein shake is best freshly blended, so that it doesn’t completely melt.
Simply make the coffee cubes and chill the coconut cream in the fridge until you’re ready to blend everything together.
How to store keto protein shakes
Store this low carb protein shake in the refrigerator, but it’s best made fresh!

Pour the brewed coffee into an ice cube tray. Freeze for at least 3-4 hours or overnight, until solid.
Meanwhile, place the can of coconut cream in the fridge at the same amount of time - the thick cream will separate from any coconut water inside after a few hours. Once you open the can, don’t shake or stir it - just skim the thick cream needed for this iced coffee protein shake recipe off the top.
In a blender, combine the frozen coffee cubes, Atkins protein shake, coconut cream, and avocado in a blender. Blend until smooth and creamy. If it's thicker than you like, you can add a little more of the Atkins shake or just wait for it to melt a little.
