Protein Coffee: 4 Easy Recipes to Try at Home

Coffee and protein might not be the most obvious combination, but put them together properly and you can create a smooth, satisfying drink that’s easy to make at home.

Protein coffee simply combines your favourite coffee with a source of protein, usually protein powder. You can make it hot or cold and experiment with vanilla, chocolate or unflavoured protein depending on the drink you want.

Whether you’re looking for something different after a workout or simply want to add more protein to your usual coffee, these four easy protein coffee recipes are a great place to start.

What is protein coffee?

Protein coffee is exactly what it sounds like: coffee combined with protein.

Most recipes use whey or plant-based protein powder, although ready-made protein drinks can also be combined with coffee.

Adding protein changes the nutritional content of your drink and can also give coffee a creamier texture, particularly when it’s blended or shaken thoroughly.

The amount of protein in the finished drink depends on the powder and serving size you use, so always check the nutritional information for your particular product.

Why add protein to coffee?

There are several reasons protein coffee has become a popular combination.

An easy way to add protein to your diet

If you already drink coffee regularly, adding protein powder can be a convenient way of increasing your protein intake.

Protein plays an important role in the body and is particularly relevant to people who exercise regularly.

The International Society of Sports Nutrition’s position stand on protein and exercise discusses the role of dietary protein for healthy, exercising individuals.

That doesn’t mean everyone needs a protein supplement. Your overall diet and individual requirements are what matter.

Useful around your training routine

A protein coffee can be a convenient drink around your normal exercise routine, particularly if you already enjoy coffee before or after training.

Coffee provides caffeine unless you’re using decaf, while the protein powder provides dietary protein.

Rather than treating the combination as a magic pre- or post-workout drink, think of it as a convenient way to combine two things you may already consume.

Plenty of ways to customise it

One of the best things about protein coffee is how easy it is to change.

You can make it with:

• Espresso
• Strong brewed coffee
• Cold brew
• Regular or decaf coffee
• Dairy milk
• Plant-based milk
• Whey protein
• Plant-based protein

Chocolate protein can turn it into something similar to a mocha, while vanilla works particularly well in a latte-style drink.

How to stop protein powder clumping in coffee

The biggest problem when making protein coffee is usually texture.

Adding some protein powders directly to very hot coffee can cause them to clump, leaving you with an unpleasant drink.

An easy way around this is to mix your protein powder with a small amount of cold milk or water first.

Whisk or shake it until smooth and then gradually combine it with your coffee.

Different protein powders behave differently, so you may need to experiment with the particular product you’re using.

A blender or handheld milk frother can also help produce a smoother result.

The golden rules of protein coffee

Before making the recipes, keep these simple tips in mind.

Mix your protein first

Combine the powder with a small amount of cool liquid before adding the coffee. This makes it much easier to create a smooth consistency.

Choose a complementary flavour

Vanilla, chocolate and unflavoured protein are obvious starting points.

Unflavoured protein lets the coffee remain the dominant flavour, while chocolate creates a mocha-style drink.

Don’t use boiling coffee

Let freshly brewed coffee cool slightly before combining it with your protein mixture.

This can make some protein powders easier to incorporate and gives you more control over the finished texture.

Adjust the recipe to your protein powder

Protein powders vary in flavour, sweetness, serving size and texture.

Treat the quantities below as starting points and adjust them according to the product you’re using.

Recipe 1: Classic Protein Coffee Latte

This simple protein coffee recipe is a good place to start if you normally drink a latte.

Ingredients

• 1 scoop vanilla or unflavoured protein powder
• 50ml cold milk or water
• 1 shot of espresso or 100ml strong brewed coffee
• Additional milk if desired
• Sweetener, optional

Method

1. Add the protein powder to a shaker or small jug.
2. Add 50ml of cold milk or water.
3. Shake or whisk until completely smooth.
4. Brew your espresso or strong coffee.
5. Allow the coffee to cool slightly.
6. Gradually combine it with the protein mixture.
7. Add additional milk if you prefer a longer, creamier drink.

This protein coffee works particularly well with vanilla powder because the flavour complements espresso without overpowering it.

Recipe 2: Iced Protein Coffee Shake

Prefer your coffee cold? This iced protein coffee is particularly easy to make with a blender.

Ingredients

• 1 scoop chocolate or vanilla protein powder
• 200ml chilled milk of your choice
• 1 shot of espresso or 100ml strong coffee, cooled
• Handful of ice
• Pinch of cinnamon, optional

Method

1. Brew the coffee and allow it to cool.
2. Add the coffee, protein powder, milk and ice to a blender.
3. Blend until smooth and frothy.
4. Pour into a tall glass.
5. Add a little cinnamon if desired.

For an even colder version, prepare your coffee in advance and refrigerate it.

You could also use cold brew instead. Our cold brew coffee guide shows you how to make it at home.

Recipe 3: Mocha Protein Coffee

Chocolate and coffee are a natural pairing, making this mocha protein coffee one of the easiest variations to experiment with.

Ingredients

• 1 scoop chocolate protein powder
• 50ml cold milk or water
• 1 shot of espresso or 100ml strong coffee
• 1 teaspoon cacao or cocoa powder, optional
• Milk to taste

Method

1. Mix the chocolate protein powder with the cold milk or water until smooth.
2. Brew your coffee.
3. Allow it to cool slightly.
4. Gradually stir the coffee into your protein mixture.
5. Add additional milk if desired.
6. Finish with a light dusting of cacao or cocoa powder.

If you already enjoy mochas, this is an easy way to introduce protein powder without completely changing the style of your drink.

Recipe 4: Creamy Protein Coffee

Rather than the original bulletproof-style recipe, this version keeps things simpler and lets you decide whether you want additional fats.

Ingredients

• 1 scoop vanilla or unflavoured protein powder
• 50ml cold milk or water
• 200ml freshly brewed coffee
• Milk to taste
• 1 teaspoon MCT or coconut oil, optional

Method

1. Brew your coffee.
2. Mix the protein powder with cold milk or water until smooth.
3. Allow the coffee to cool slightly.
4. Combine everything in a blender.
5. If desired, add a small amount of MCT or coconut oil.
6. Blend briefly until smooth and frothy.
7. Pour into your favourite coffee cup.

The additional oil is entirely optional. Protein coffee doesn’t need added fat to work, and leaving it out produces a simpler everyday drink.

What protein powder works best in coffee?

There’s no single protein powder that’s best for everyone.

Whey protein is popular because it’s widely available and comes in plenty of flavours. Plant-based protein powders can also work, although their texture and flavour can differ significantly.

For coffee, we’d start with:

• Vanilla protein for lattes
• Chocolate protein for mocha-style drinks
• Unflavoured protein when you want the coffee flavour to dominate

Whichever you choose, check the manufacturer’s preparation instructions and nutritional information.

What’s the best coffee for protein coffee?

The best coffee depends on the recipe.

Espresso is an excellent choice for milk-based drinks because its concentrated flavour can remain noticeable after protein powder and milk are added.

Strong brewed coffee works well when you want a larger drink, while cold brew is particularly useful for iced recipes.

If you’re using flavoured protein powder, think about how its flavour will interact with your beans.

Chocolate and vanilla protein powders can work particularly well with coffees that have chocolate, caramel or nutty characteristics.

Our guide to choosing the best coffee beans can help you find a coffee that suits your preferred brewing method and flavour.

Can you make protein coffee without an espresso machine?

Absolutely.

You can make protein coffee using almost any method that produces a coffee you enjoy.

Options include:

• Cafetière
• AeroPress
• Moka pot
• Filter coffee machine
• Pour-over
• Cold brew

For milk-heavy recipes, make the coffee slightly stronger than you normally would so its flavour doesn’t disappear once everything is combined.

Our AeroPress brewing guide and cafetière guide are useful starting points if you don’t have an espresso machine.

Can you use plant-based milk?

Yes.

Oat, almond, soya and other milk alternatives can all be used, although each changes the flavour and texture of the finished drink.

Some plant-based milks also blend more smoothly with particular protein powders than others.

Experiment to find the combination you prefer.

For more help choosing one, read our guide to the best milk alternatives for coffee.

Is protein coffee a meal replacement?

Not necessarily.

A scoop of protein powder and a cup of coffee don’t automatically provide all the energy, fibre, vitamins, minerals and other nutrients you’d expect from a balanced meal.

The nutritional content depends entirely on what you put into your drink.

If you’re using protein coffee as part of your diet or training routine, consider it alongside everything else you’re eating rather than assuming it automatically replaces breakfast.

Make protein coffee at home

Protein coffee is easy to make, highly customisable and works with many of the brewing methods you may already use.

Start with a classic latte, try an iced version or combine chocolate protein with espresso for a mocha-style drink. Once you’ve found a combination you enjoy, adjust the quantities to suit your coffee, protein powder and preferred consistency.

For the coffee itself, browse our freshly roasted CoffeeHype coffee and choose a blend or single-origin coffee to suit your recipe.
