This High Protein Chocolate Mousse tastes just like a classic chocolate mousse—but it’s healthy and packs 15g of protein per serving! It’s the perfect dessert to meal prep for the week if you’re after something high in protein and truly delicious.
I was on the hunt for a high-protein chocolate mousse recipe the other day, and honestly, I wasn’t impressed with what I found. Most recipes were made with yogurt and chocolate protein powder. And while those can be tasty, they just don’t feel like a real chocolate mousse to me.
I wanted a proper chocolate mousse—just with more protein. When I couldn’t find one, I figured: why not just create my own recipe? So I did. And it turned out even more delicious than I expected.
The texture and flavor are spot on—just like a traditional chocolate mousse—but with 15g of protein per serving, which is exactly what I was looking for.
This protein mousse is made with chocolate protein powder, a splash of milk or water, melted dark chocolate, and whipped egg whites for that light, fluffy texture and extra protein boost.
I’ll be making this protein chocolate mousse on repeat—it’s that good. I can’t wait for you to try it!It’s also super easy to make—the hardest part is just waiting for the chocolate mousse to set. But I promise, it’s worth the wait!

Ingredients Needed:
These are the ingredients you’ll need to make this High Protein Chocolate Mousse. You can find the exact measurements in the recipe card at the bottom of this page.
Dark Chocolate – Gives this mousse its deep, rich chocolate flavor. Choose one that’s 70% or higher for a more intense taste and less sugar. Dark chocolate is packed with antioxidants and can help reduce cravings while satisfying your sweet tooth. Use a refined sugar-free option if preferred for an even healthier twist.
Chocolate Whey Protein Powder – Adds a creamy texture and rich cocoa flavor while packing in a solid protein boost. It helps balance blood sugar, promote satiety, and support muscle repair. Make sure you use one that tastes good on its own and has minimal additives. Please note: I use USN Chocolate Whey Protein – I have not tested this recipe with any other protein powders.
Milk or Water – Helps blend the protein powder into a smooth, glossy base. Milk (dairy or non-dairy) adds extra creaminess and nutrients like calcium and vitamin D, while water is a great low-calorie option that keeps things light.
Egg Whites – Whipped to stiff peaks, they create that signature mousse texture and add extra protein without fat or cholesterol. Egg whites are low in calories and high in high-quality protein, perfect for a lean dessert.
Ingredient Substitutions:
Dark Chocolate: You can swap this with dairy-free chocolate or a lower-sugar variety. If you use milk chocolate, note that the end result may be sweeter and slightly softer—you may need to reduce the milk or water slightly.
Chocolate Protein Powder: Feel free to use plant-based protein instead of whey. Just be aware that some plant proteins absorb more liquid, so you might need to adjust the liquid slightly to get the same smooth texture.
Milk or Water: Any milk will work here—almond, soy, oat, or cow’s milk. Water is great for a lighter option, but milk adds creaminess.
Egg Whites: For a vegan alternative, try using aquafaba (the liquid from a tin of chickpeas). Whip it just like egg whites—the texture won’t be exactly the same, but it still gives a nice airy feel.
Note: Substitutions may affect texture or flavor, so you may need to slightly adjust quantities to maintain the best mousse consistency.
Equipment Needed:
- Mixing bowls: One for combining your base, another for whipping the egg whites.
- Electric whisk or stand mixer: Essential for whipping egg whites to stiff peaks.
- Rubber spatula: For gently folding the egg whites into the chocolate mixture without deflating them.
- Microwave-safe bowl or double boiler: For melting the chocolate until silky smooth.
- Measuring cups and spoons: To make sure your ingredients are perfectly portioned.
- Serving jars or ramekins: For portioning the mousse once it’s ready to chill.
How to Make This Chocolate Protein Mousse:
Here is a detailed summary of how to make this recipe. I’ve also included some photos, and you can find the recipe video in the recipe card. At the bottom of this page is a summarized version that can be printed.
Step One:
Break the dark chocolate into pieces and melt it gently using a double boiler or in the microwave in 30-second bursts, stirring in between until smooth. Let it cool slightly so it doesn’t cook the egg whites later.
Step Two:
In a separate bowl, whisk the chocolate protein powder and milk (or water) until you get a smooth, lump-free, glossy mixture.
Step Three:
Stir the cooled melted chocolate into the protein mixture until it’s fully combined.
Step Four:
In a clean, dry bowl, whip the egg whites to stiff peaks using an electric whisk or stand mixer.
Step Five:
Gently fold the whipped egg whites into the chocolate mixture in batches, being careful not to knock out too much air. You want the mousse to stay fluffy and light.
Step Six:
Divide the mixture into 2–4 ramekins or jars and refrigerate for at least 1 hour, or until fully set.
Step Seven:
Once set, serve the mousse chilled. Let it sit at room temperature for about 5–10 minutes before serving for the best texture. Enjoy it on its own or with a topping of crushed nuts, cacao nibs, or a drizzle of extra dark chocolate for an indulgent finish.
Tips and Notes:
- Extra Chocolatey: Stir in a teaspoon of raw cacao powder for an even deeper chocolate flavor.
- Make It Dairy-Free: Use dairy-free chocolate and your favorite plant-based protein powder to keep the recipe completely dairy-free.
- Add a Crunch: Top with crushed nuts, cacao nibs, or a sprinkle of granola before serving.
- Vegan Option: Replace egg whites with aquafaba—the texture will be slightly different but still fluffy and delicious.
- Protein Boost: Want even more protein? Add a few tablespoons of Greek yogurt (or a dairy-free alternative) to the protein-chocolate mix before folding in the egg whites.
- Meal Prep Friendly: Make a double batch and store it in the fridge for a high-protein dessert all week long.
- Flavor Twist: Add a drop of peppermint or orange extract for a fun flavor change.
How to Store Protein Chocolate Mousse:
Refrigeration: Store in airtight jars or containers in the fridge for up to 4 days. The texture stays soft and mousse-like, making it perfect for prepping ahead.
Freezing: You can freeze the mousse, but the texture may change slightly when thawed. If you try it, let it defrost in the fridge for a few hours before eating. It also makes a delicious frozen treat straight from the freezer!
Serving Tip: For the best texture and taste, let the mousse sit at room temperature for 5–10 minutes before serving.
Frequently Asked Questions:
Can I make this without protein powder?
Yes! You can replace the protein powder with 1–2 tablespoons of cocoa powder and a bit of extra sweetener if needed, though it won’t have the same protein content.
What if I don’t eat eggs?
You can use aquafaba (the liquid from chickpeas) in place of egg whites. It whips up just like egg whites and keeps the mousse nice and airy.
Can I use casein or plant-based protein?
Yes—just know the texture might change slightly. Casein tends to make things thicker, and some plant proteins absorb more liquid, so adjust the milk or water as needed.
Can I eat it right away?
Technically yes, but the texture improves SO much after chilling. Give it at least an hour for that proper mousse feel.
Is it safe to eat raw egg whites?
Use pasteurized egg whites (from a carton or safely separated from eggs) to reduce the risk. Or go for aquafaba if you prefer a vegan or egg-free option.

Notes
Please note: I use USN Chocolate Bluelab Whey Protein – I have not tested this recipe with any other protein powders.
TIPS & NOTES:
- Use good-quality chocolate: Since chocolate is the star here, using a high-quality dark chocolate (70% or higher) will give the best flavor and texture.
- Let the chocolate cool slightly before mixing: If the melted chocolate is too hot, it could seize when added to the protein mixture or deflate the egg whites.
- Whip egg whites to stiff peaks: You want the egg whites to be fluffy and hold their shape when you lift the whisk—this is key to getting that classic mousse texture.
- Fold gently: Don’t rush the folding process. Gently folding in the egg whites helps keep the mousse light and airy. If you overmix, the mousse can turn dense.
- Chill time: While the mousse sets after about 1 hour, the texture improves even more if you let it chill for a few hours or overnight.
- Serving ideas: Top with a dollop of Greek yogurt, a few berries, or a sprinkle of shaved chocolate for extra indulgence.
- Meal prep friendly: This mousse stores well in the fridge for up to 3–4 days, making it perfect for prepping ahead as a post-dinner treat or snack.
