As someone who gets a lot of exercise, I need quite a bit of protein in my diet. And this Coffee Protein Shake is my new favorite way to refuel after a tough workout. It’s cold and refreshing, with a kick of caffeine and plenty of protein.

Best of all, it tastes like a keto frosty! It’s so thick and creamy, you can almost imagine that you’re slurping down a mocha milkshake.

Sugar-free energy never tasted so good. You won’t ever pay for pre-made keto shakes again with this recipe at hand. And it’s fabulous as breakfast or a snack!

Why you will love this recipe

This coffee protein shake is so easy to make, and is the perfect blend of energy and refreshment. And with only six clean, keto-friendly ingredients, you know exactly what you’re getting.

Because the coffee is frozen into cubes, this keto shake doesn’t get watered down by melting ice. It stays creamy and rich for as long as it takes you to drink it. It’s also completely nut-free and can be made dairy-free as well, so it works with any dietary restrictions.

Make it your own by switching up the flavors of protein powder, adjusting the level of sweetener, or adding in some chocolate chips. At 1.4 grams of carbohydrates, you can customize it to suit your tastes and your macros.

Coffee: Cold brew is a good choice for this recipe, as it has a good strong flavor. But you can use any cold coffee, including espresso. You can also use decaffeinated.
Low carb milk: I like to use hemp milk in smoothies and shakes, as it has no carbs. But you can also use almond milk or macadamia milk. Just be sure to choose the unsweetened variety.
Whipping cream: Heavy cream adds richness and thickness to this keto protein shake.
Collagen protein powder: Also referred to as collagen peptides, it’s a great source of protein and adds thickness to shakes and smoothies. But you can also use whey, egg white, or plant protein in this recipe. Feel free to play with different flavors of protein as well. Chocolate, vanilla, and salted caramel would all be lovely.
Swerve Confectioners: Swerve is my go-to sweetener for almost all of my recipes. It adds the perfect amount of sweetness to keto treats. And the Confectioners-style sweetener blends perfectly into shakes and smoothies.
Cocoa powder: A little cocoa powder makes these Coffee Protein Shakes taste like a mocha milkshake. But you can skip it if you like.

Expert tips and FAQ

A standard ice cube tray will make enough coffee cubes for two protein shakes. But you can easily make one and store the remaining cubes in the freezer for another day.

If the protein powder you use is unsweetened, you may want to add an additional tablespoon of Swerve Confectioners to the shake. You can easily taste and adjust the sweetener after the ingredients are blended together.

Dairy-Free Option: You can make this shake dairy-free by replacing the whipping cream with full fat coconut milk or coconut cream.

How many carbs are in a coffee protein shake?

This easy shake recipe has 2.9 grams of carbohydrate and 1.5 grams of fiber. Thus they have only 1.4g NET CARBS per serving.

Can you have a protein shake on keto?

Be wary of pre-made protein shakes or mixes. Even ones that label themselves as “keto” often have quite a few carbs and/or some sketchy ingredients. Read the labels carefully. Better yet, make your own keto protein shake at home!

Can you make coffee protein shakes in advance?

I don’t recommend making these more than 30 minutes in advance as they do melt. The flavor doesn’t get watered down but they do become more liquid as they sit at room temperature. If you keep the shake in an insulated mug, it will stay colder longer.

You can also make the coffee ice cubes in advance so you have them ready to go at any time. They will last in the freezer for months.
