Also before bed. And, when you’re feeling down. Because it will make you happy. Happy and strong. I just love this thing!

Can you make hot whey protein

You must be thinking, whey hot chocolate? How is it possible? That’s probably because you heard that hot milk destroys whey protein. But that’s not exactly true.

When adding hot liquid to whey, the heat causes denaturation and aggregation (i.e. clumping) of the milk proteins. But the protein nutrients remain unchanged. It’s similar to what happens to an egg white when you fry it, but less pretty.

As I hopelessly witnessed myself when first trying whey protein coffee, whey powder will curdle immediately with hot liquid, forming unsavory clumps. (Which can make one really sad when stuck in a hotel room with ridiculously expensive protein options on the menu)

But that doesn’t mean you cannot have whey protein hot! You just need to follow this mixing technique to avoid curdling:

How to mix whey protein with hot milk

To make hot whey protein without clumps, you need first to form a paste with the whey protein powder and a little bit of room temperature liquid.

You can use plain water or a smaller amount of whatever liquid you plan on adding hot: regular or low-carb milk, coffee, tea, etc.

Forming a paste will pre-dissolve the whey powder and “relax” the proteins, so when you add the hot milk (or coffee, or water) they won’t clump and curdle!

Ingredient notes

Whey protein: I used unflavored whey for this recipe, as I do for most recipes on LikeHotKeto. You can also use any flavored protein that will taste good with hot chocolate. The options are endless. Here’s some, from the top of my head:

Vanilla, chocolate (duh) and all chocolate variations (think, Mexican hot chocolate?), peanut butter, brownie, cookies & cream, coffee, caramel, cappuccino, cinnamon, mocha, hazelnut.

Honestly, I think the only protein flavor family that wouldn’t go well with this hot chocolate mix recipe is fruit.

Ingredients for the keto whey protein hot chocolate.

Altering recipe for flavored whey: Because flavored whey powders are already sweetened and usually contain thickeners, you can half the amount (or maybe leave out entirely) of the keto sugar substitute and xanthan gum.

This will depend on the specific properties of your flavored whey. I suggest you make one mug and try it out before making the whole mix, and adjust what you need.

Cocoa powder: Pure cocoa powder, or baking cocoa. I love using this Dutch process cocoa because of it’s intense, chocolatey flavor and darker color. But any sugar-free, pure cocoa powder you like will do!

Sugar substitute: Your preferred keto sweetener, such as erythritol, allulose, xylitol or blends of those with added stevia or monk fruit – like my homemade keto sweetener recipe.

Low-carb milk: Use you favorite keto friendly, low-carb milk. Nut milks such as almond and macadamia are good, or just mix a couple tablespoons of heavy cream into a glass of water for a quick keto milk substitute.

Salt and baking soda: These are not strictly necessary, but salt makes the chocolate flavor pop, and the baking soda takes out some of the acidity (specially if you are using natural cocoa powder instead of alkalized, aka Dutch) and helps create that lovely foam on the top of the hot chocolate!

Xanthan gum: You know the recipes that make you whisk hot chocolate in a pan on the stove top to thicken!? Well this isn’t it!

Just a little bit of xanthan gum makes this chocolate mix thick and super creamy instantly, as you add in the hot milk. It’s so decadent! The texture is almost like molten chocolate.

Chocolate chips (or shaved chocolate): this is optional, and although it makes for a extra decadent hot chocolate experience, I often skip.

This is because I usually make a whole jar of keto hot cocoa mix, just by shaking the ingredients together, and adding the chips in makes a bit complicated to stir the whey into a smooth paste. It’s hard to tell if the little pieces are chunks of chocolate or lumpy whey.

If you mix by the individual mug, just add the chips right before adding the hot milk. If you want to add the chocolate chips or shavings to the whole 6-serving whey protein cocoa mix recipe, I recommend you blend the mix in a food processor for easier mixing.

How to make

One mug of protein hot chocolate

To make one mug of keto protein hot chocolate, start by adding the powder ingredients for a single serving (cocoa powder, whey protein, pinch of salt, pinch of baking soda, sweetener and xanthan gum) to a large mug and combine.

Step by step instructions of how to mix the whey protein hot chocolate.

Then, add 2 or 3 tablespoons (start with 2, go up to 3 if needed) of the room temperature or warm low-carb milk you will use.

Mix it very well, until you form a smooth paste with the whey. It should look almost like Nutella. Don’t eat it yet! Add the chocolate chips (if using).

Get the remaining low-carb milk piping hot. Add a small amount of milk to the paste, and mix to dissolve it. Add the remaining of the hot milk, slowly, while mixing. Done!

Put all dry ingredients for the keto hot cocoa mix to a large, airtight container or mason jar. Shake it, SHAKE IT, shake it until fully mixed. That’s it!

You can also use a food processor to mix the ingredients. I recommend doing this if you’d like to add chocolate chips, as it will be easier to mix the whey protein paste until smooth for the hot chocolate.

To make a mug of protein hot chocolate from the cocoa mix, add 2 full scoops (standard sized 30 grams/1 oz whey protein scoops) or about 4-5 tablespoons of the mix to a large mug, and proceed with the single mug preparation steps described above.

The LikeHotKeto whey protein hot cocoa mix will last a long time in an airtight sealed jar. I assume it should be good until the “best by” date of the ingredient that is nearer to it. It has never gone bad on us (it has sat for a couple of months on occasion).

Hot chocolate and protein shake: why not have both? This homemade keto hot cocoa mix is the most decadent post workout you could wish for!

Prep Time 5 minutes

Total Time 2 minutes
Course Drinks
Cuisine Low-carb
Servings 1 individual mug or ~1 pound of hot cocoa mix


For single serving (one mug) preparation:

  • 1 scoop (30 g) unflavored whey protein powder see Notes for flavored protein options
  • 2 tablespoons cocoa powder
  • 1 to 2 tablespoons keto sweetener To taste, see notes
  • teaspoon xanthan gum
  • 1 pinch baking soda
  • 1 pinch sea salt
  • 2 tablespoons (30 ml) low-carb milk cold
  • ¾ cup (180 ml) low-carb milk hot
  • 1 tablespoon dark chocolate chips optional

For protein hot chocolate mix (makes about 1 pond or 6 mugs):

  • 6 scoops (180 g) unflavored whey protein powder see Notes for flavored options
  • 1 cup (88 g) cocoa powder
  • ½ to 1 cup (100 to 200 g) keto sweetener To taste, see notes
  • 1 teaspoon xanthan gum
  • teaspoon baking soda
  • teaspoon sea salt
  • 6 tablespoons dark chocolate chips optional


Single serving (one mug)

  • Add in a large mug 1 scoop unflavored whey protein powder, 2 tablespoons cocoa powder, 1 to 2 tablespoons keto sweetener, 1/8 teaspoon xanthan gum, 1 pinch baking soda and 1 pinch sea salt.
  • Add 2 tablespoons low-carb milk cold or at room temperature (not hot) and mix well, making a thick paste free of lumps. If needed, add a tiny bit more milk, just enough to form a paste.
  • Slowly add hot 3/4 cup low-carb milk while mixing, and serve immediately.

Protein hot chocolate mix

  • Put all ingredients in a food processor and pulse a few times to mix. Alternatively, add all ingredients to fill up to two thirds of an airtight container, and vigorously shake for a minute or two until completely mixed.
  • To prepare the protein hot chocolate from the mix, add 4 to 5 tablespoons of the mix into a mug, and follow steps 2 and 3 of the single serving preparation instructions above.


  • Sweetness level: Use the lower amount of the keto sugar substitute (erythritol, allulose, xylitol) for a hot chocolate taste (slightly sweet, more chocolate-y) or the larger amount for a hot cocoa taste (quite sweet, like regular cocoa powder mix). I personally like it in between☺
  • If using a flavored whey protein powder, you might not need adding sweetener as they are often very sweet. Flavored whey powders usually contain thickeners, so xanthan gum may be halved or removed entirely.
  • For any chocolate flavored whey (like this Mexican Chocolate whey – made for hot chocolate!), you can reduce the cocoa powder in the recipe by half.
  • If the prepared drinking chocolate is not hot enough (it can happen if the hot milk added was not piping hot), you can put the mug in the microwave to heat it up. It will not curdle or damage the protein, as it's already dissolved.
  • Adding about 1 tablespoon of keto chocolate chips or sugar-free shaved chocolate per mug will make this hot chocolate even more decadent. Add chips in just before the hot milk and they will melt as you mix.
  • You can add sugar-free marshmallows or whipped cream topping if you like!
  • Nutritional information shown is for portion (single mug) of the hot chocolate mix powder without milk or toppings.

  1. SO easy to make! I prepared a single mug recipe first to see if I liked it. I immediately got all ingredients out again to prepare the full mix! I used monk fruit as sweetener.
