Mixing protein and coffee has become the latest trend on social media, but is ‘Proffee’ a good idea?

The good news is that mixing protein with coffee will increase your protein intake and can aid weight loss. However, the bad news is that if you don't mix it the right way, it may not be drinkable.

In this guide, I’ll show you all the benefits of protein powder in your coffee and the best ways to make your own proffee at home.

It's perfectly safe to put protein powder in coffee, but if you don't do it correctly, you can ruin your coffee's taste and texture.

Protein Coffee Taste

Coffee has a bold and unique flavor. On the other hand, the taste of protein powders can vary significantly. There are a lot of different flavors of protein powders, and adding them to coffee results in a mix of two very different flavors.

To make good tasting protein coffee, you need to select the right flavor of protein. I suggest using vanilla, chocolate, or caramel. These flavors work well with coffee and are already used for many coffee drinks (like caramel lattes or mochas).

Using other flavors to get a protein boost can leave you with a bad-tasting beverage that's hard to drink.

Protein Coffee Texture

Coffee is a liquid, so you don't expect it to have too much texture. However, when you add protein powder to coffee, you're mixing a solid with a liquid, and that doesn't always end well.

You usually mix whey protein powder in a shaker to create a drink, and even then, it can end up with clumps. It's a bit more challenging to shake coffee with protein powder (especially if it's hot), and this can also leave you with some clumps.

To create a protein coffee with a good texture, you need to:
  1. Pick protein powders that mix well.
  2. Use an electric hand mixer to combine it with the coffee. You should also add the protein bit by bit to avoid any lumps.
So, does coffee with protein powder taste good?

Yes, adding protein powder to your coffee can make a tasty drink that is good for your health - but only if you choose the best protein powder and combine it properly.

What Kind Of Protein Powder Should You Add To Your Coffee?

You can add basically any protein to your coffee. Most people use whey protein, but most protein powders will work.

However, you shouldn’t use soy protein powder in your proffee as it can cause bloating, acid reflux, and constipation.[1]

The best protein powders for your coffee should:

  • Blend well - When combining protein with coffee, you need to make sure it will mix well, so look for a water-soluble brand.
  •  Have no flavor or the right flavor - using protein supplements with no flavor (like collagen powder made from collagen peptides) is usually best, but you can also use chocolate, caramel, or vanilla protein powder. Also, remember that many protein supplements contain artificial sweeteners and can be used instead of sugar.
  • Be free from other supplements - some protein powders contain other supplements, often caffeine or another natural stimulant. This can be dangerous to mix with coffee as you can have too much caffeine in one drink.

You can also add a protein shake to your coffee to get the same benefit. Protein shakes are blended already and combine more easily with regular coffee, making a better-tasting drink.

Is There A Difference To Adding Protein Into Cold Or Hot Coffee?

It’s easier to add protein to cold coffee than it is to hot coffee. This is because the heat can break down the amino acids in the protein structure, causing it to clump.[2] When you add protein powder to cold or iced coffee, this doesn't happen.

If you're making an iced coffee protein shake, you can just combine the ingredients and blend. If you use a very soluble protein powder, you can usually just shake it together by hand.

If you're making a hot protein coffee, you need to combine the protein powder and milk gradually, using a milk frother to combine it together. Only once it's combined can you add it to your hot brewed coffee.

5 Benefits Of Mixing Protein In Coffee

1. Increased Satiety

Adding protein to your morning cup of coffee can leave you feeling fuller for longer.[3]

Protein powder's nutritional content will vary as some are used for weight loss and others for weight gain, but adding them to coffee will generally mean you consume more calories. This can help you feel fuller for longer and avoid other food.

Remember, coffee and protein powder is no substitute for a balanced breakfast, but they can stop you from feeling cravings for unhealthy foods.

2. Improved Muscle Recovery

One of the key benefits of protein is that it’s been proven to support muscle growth and recovery.[4] Combining coffee with protein helps you achieve a high-protein diet, which will help build muscle mass.

3. Increased Energy

If you're normally drinking coffee and protein shakes separately, then you might not get the same energy boost as you do from having a delicious proffee. Combining them will give you the caffeine boost to help you through your exercise, while the protein protects your gains and helps you grow stronger.

4. Improved Nutrient Intake

Coffee consumption alone doesn't contain many nutrients, but proteins have beneficial fatty acids, which have many potential benefits, including preventing liver disease and other additional health benefits.

It totally depends on what protein you use, but adding protein powder to your morning coffee could give your body more of the ingredients it needs.

If you are looking to add protein to your coffee regularly, then it's worth looking for a powder with added vitamins and nutrients.

5. Weight Management

Combining protein with coffee boosts weight loss just because you're consuming more protein. Having enough protein is key for managing your body weight and losing body fat while helping you build muscle.[5] By adding it to your coffee mug, you can actually lose weight.

Recipe Ideas For Protein Powder And Coffee Mix (Proffee)

Hot Coffee Protein Recipe

A hot coffee protein is the perfect low-calorie breakfast. If you're avoiding dairy products, follow this recipe to create a delicious drink that supports your muscle building.

You’ll Need:
  • 1-2 scoops of protein powder (roughly 20-30 grams of protein). It’s best to use vanilla or chocolate with this recipe, or you can use another flavor that works well with coffee.
  • 8 - 12 oz of hot brewed coffee
Instructions:
  1. Pour your warm coffee into a blender (you can also use an immersion blender if that's all you have)
  2. Add half a scoop of protein powder
  3. Mix for 30 seconds
  4. Add another half a scoop of protein powder
  5. Mix for another 30 seconds
  6. Keep adding the protein powder gradually and blending, so there's no chunky texture
  7. Once you've finished, pour into a cup and add whatever milk or sugar you like

Hot Coffee Protein with Milk Recipe

Protein combines well with milk, so the trick to a milky protein coffee is to blend the powder with the milk before you add it to the warm coffee. You can use dairy milk, almond milk, oat milk, soy milk, or any non-dairy milk you like for this recipe.

You’ll Need:
  • 20-30 grams of protein powder (1-2 scoops). Again, vanilla or chocolate is best, but you can choose whatever flavor you prefer.
  • 8 - 12 oz of brewed coffee or instant coffee
  • 1-2 oz of Milk
Instructions:
  1. Pour your milk into a small saucepan
  2. Start putting protein powder into the milk and use a handheld blender to combine
  3. Keep adding the protein slowly until it's all combined. Stir continuously, so there are no lumps in the mixture
  4. Slowly warm the milk and protein combination in the pan
  5. Add the warm milk to the coffee to create your proffee
  6. Add in any extra milk, sugar, or sweetener to suit your tastes. You can even add cocoa to give it a chocolatey flavor. Then, enjoy!

Iced Protein Coffee Recipe

An iced proffee is an easy way to get extra protein into your diet. Protein combines more easily with cold coffee, so it’s actually easier to create a coffee iced latte than a hot protein coffee.

You’ll Need:
  • 8 - 12 oz of brewed coffee which has cooled, or cold brew coffee
  • 1 - 2 scoops of protein
  • Ice
Instructions:
  1. Pour the coffee into a shaker and add the protein powder
  2. Shake the mixture together until the protein has combined
  3. If the protein doesn't combine, you may need to use a blender
  4. Pour over ice and use a coffee stirrer to mix
  5. Add any syrups, milks, sugars, or sweeteners you want to taste
