Coffee Protein Shake
This post may contain affiliate links. See my disclosure policy.
My coffee protein shake recipe combined the refreshing coffee flavor with protein-packed ingredients. It’s creamy, thick, and packs in 24 grams of protein per serving.

Coffee and protein are two non-negotiables in my morning routine, and when I can pair the two together, even better. With the energizing boost of caffeine and the staying power of protein powder (inspired by my protein coffee!), this shake has become a weekly staple in my house- and you’ll see why!
When I tested this recipe, I tried both chilled espresso and cold brew to compare the flavor. Cold brew came out on top for smoothness, but I know not everyone keeps it on hand (although if you try my homemade cold brew concentrate, you’ll never be without it again). Chilled brewed coffee works just as well. Once you blend it with protein powder, frozen banana, and ice, you get an energy-boosting protein shake that tastes like dessert.

Why this coffee protein shake is a staple
- The best of both worlds. It basically tastes like a coffee milkshake, but it’s made with wholesome ingredients.
- Packed with protein. One scoop of protein powder gives this shake over 24 grams of protein, making it the perfect pre- or post-workout treat. You can even double it.
- Ready in seconds. Throw everything in your blender and blend until smooth.
- Cheaper (and tastier) than store-bought. I recently broke up with store-bought protein shakes in favor of making them at home.
Key Ingredients

Find the printable recipe with measurements below.
- Protein powder. I tested various protein powders (casein, whey, vegan), and the type didn’t seem to make a difference. I do recommend a vanilla-flavored one for some added sweetness.
- Banana. Preferably a frozen banana, so it keeps the shake cold and creamy.
- Milk. I used unsweetened almond milk, but any dairy or non-dairy milk works.
- Chia seeds. For added protein, fiber, and healthy omega-3 fatty acids. It also thickens the shake, too.
- Cold brew coffee. Skip the store-bought stuff and use my homemade cold brew concentrate. You can also use chilled instant coffee. Don’t want the caffeine but want the flavor? Use decaffeinated coffee.
- Ice. Adding ice thickens the shake, almost similar to a frappuccino!
- Sweetener. Optional, depending on how flavorful your protein powder is. I ended up adding a little maple syrup, but you could use honey, agave, or sugar-free maple syrup.
Tested recipe variations
Here are some ways I’ve tweaked this shake to fit into my needs (and the time I enjoy it):
- Double protein. I usually keep this shake to one scoop of protein powder (about 1/4 cup), but if I’m having it post workout, I’ll double it for an extra boost. It doesn’t affect the texture at all, so you get still get a smooth, creamy shake- just with more staying power.
- Mocha coffee protein shake. Use chocolate protein powder and add a tablespoon or two of cocoa powder for a richer flavor.
- Extra coffee boost. Add one teaspoon of instant coffee, or replaxe some milk for a shot of espresso.
- Healthy fats for breakfast. If I’m having this shake for breakfast, I like adding some healthy fat to keep me fuller for longer. Almond butter, frozen avocado, or full-fat Greek yogurt are great options.
- Creamy elements. I sometimes add some Greek yogurt or a scoop of protein ice cream.
How to make a coffee protein shake

Step 2- Blend everything until smooth.

Step 2- Serve. Pour the mixture into a glass and enjoy!
Pro tips for success
- Coffee ice cubes. This is my sneaky hack I picked up back in my college weightlifting days. Instead of using plain ice (which waters down the shake), freeze brewed coffee or cold brew in an ice cube tray. Blend those and you’ll get a thicker texture plus an extra coffee kick.
- Adjust the consistency. This shake is naturally thick, like a smoothie or milkshake. If you prefer it thinner, add a splash more milk until it’s the texture you like.
- Taste as you go. One of the perks of this recipe is how customizable it is. I always give it a quick taste and adjust – sometimes I’ll add more sweetener, a pinch of cinnamon, or even extra protein if I’m making it post-workout.
Frequently asked questions
Yes, if you aren’t a fan of bananas, you can swap them out for 1/2 a cup of frozen coconut chunks, frozen cauliflower (seriously!), or extra ice. I tested all three while recipe developing, and while the texture is slightly less creamy, the flavor of the coffee and protein powder still shines.
I don’t recommend it. Hot coffee melts the ice and separates the protein powder from the milk. If you only have hot coffee on hand, let it cool completely in the fridge first. Alternatively, you can brew a shot or two of espresso and dilute it with the milk before blending.
I tested this with every mainstream protein powder blend: whey, casein, brown rice, and pea protein. It all worked well. Casein and brown rice protein gave the best milkshake-like texture. If you can, vanilla protein powder is best for added flavor and sweetness.
Yes, I sometimes make two shakes at once and keep one in the fridge overnight. When ready to enjoy, give it a good stir. For more extended storage, freeze the mixture in large ice trays and blend with some milk when ready to enjoy.

Delicious!!!!
What is substitute for chia? Psyillum would be okay?
Today morning tried this recipe. It was really good. Different style of coffee.
Is it possible to make this without using banana?
For sure 🙂 I’d add more ice to compensate and either some maple syrup or honey.
I dont know to what I am more addicted-coffee or whey protein haha!
So yummy and easy! I used chocolate protein powder because that’s what I had. It made a delicious, creamy, thick protein shake that I enjoyed for lunch on this hot summer day.
This is a good, basic “starter” recipe to which I add 15ml organic MCT oil; I don’t eat/use almonds (or peanuts b/c of their lectins–so I sub with organic coconut milk; I add 7g organic ground flax seed; my water is RO mineral water from my home system. I use organic coffee (whole bean) that I grind per use. I take organic Vit C and D capsules, so I add them whole for my blender to pulverize.
I am addicted to coffee. So for sure will try this one!
Wow this will be instead of my black coffee, gaining weight hehe!
Coffee is my favourite flavour!
Can you sub the cold brew for shots of expresso
Oh yes!!! I do this often (when I have cold brew!!).
Love this coffee protein shake. I was skeptical if it would mix in well.
Just made it, it’s SO creamy!!! and a solid caffeine hit.
Thanks Audra!
Best coffee protein shake recipe ever!!!
It’s so good!!!
This looks amazing. You’ve noted the protein powder used was Bourbon Vanilla but the link is for creamy vanilla. Could you please share what Bourbon vanilla powder was used? I look forward to trying this! Thank you
This might be a silly question, but can you taste the banana? I’m not a huge banana fan and I’m wondering if the coffee flavour covers the taste of banana? Thanks.
