Keto Protein Mousse

Make your dessert work for you with this easy Protein Mousse recipe. Rich and creamy, this sugar-free treat has 14g of protein in every serving!

You know I love making a decadent dessert that defies expectations. Especially a rich, creamy dessert that has all the flavor and texture of the sugary kind, without all the sugar.

For me, mousses of all flavors are a particular favorite. I adore the airy texture, the silky mouthfeel, and above all, the heavenly flavor. I have many wonderful recipes, including Keto Peanut Butter Mousse and my classic Keto Chocolate Mousse.

And the delightful thing about mousse is that it’s infinitely adaptable. It can be so many different, delicious things with so many variations. It can even be a healthy, high-protein dessert or snack!

If you want a treat that helps fuel your body while delighting your tastebuds, look no further than this Chocolate Protein Mousse.

Why you will love this recipe

The wonderful part about this healthy protein mousse is that it takes only about 5 minutes of your time to make. You can eat it straightaway, or allow it to firm up more in the fridge for a few hours.

It has a rich chocolate flavor and a super creamy mouthfeel. And it packs a whooping 14g of protein per serving, without any added sugars and only 3.9g net carbs. It tastes like an indulgent dessert, but offers a wonderful nutrition profile.

As long as your cottage cheese and heavy cream are fresh, the mousse will last in the fridge for up to 5 days. You can also use it in other fun ways, turning it into popsicles or even putting it in your Ninja Creami!

Ingredient Notes

• Cottage cheese:  I use part-skim cottage cheese to help keep the fat content down a bit, but any variety should work.
• Protein powder: For this mousse recipe, I like using chocolate whey protein powder. See the Tips for Success for more options.
• Espresso powder: This is an optional ingredient but it helps intensify the chocolate flavor. You can more if you want a mocha flavor.
• Heavy whipping cream: Folding whipped cream into the chocolate makes it extra light and fluffy.
• Sweetener: Any powdered sweetener should work in this recipe.
• Cocoa powder: For a deeper chocolate flavor, I recommend using Dutch process cocoa. It also blends better into the other ingredients.
• Vanilla extract: A little vanilla helps enhance the chocolate flavor in this mousse recipe.

Step by Step Directions

1. Blend the cheese: In a blender or food process, combine the cottage cheese, chocolate protein powder, and espresso powder. Blend until smooth.

2. Whip the cream: In a large bowl, combine the heavy cream, sweetener, cocoa powder, and vanilla extract. Beat together until the cream holds stiff peaks.

3. Fold together: Add the cottage cheese mixture to the whipped cream, gently folding together to avoid deflating the peaks as much as possible.

4. Chill to set: Divide the mixture between 4 dessert glasses and chill until it firms up, 1 to 2 hours.

Tips for Success

If the cottage cheese you use is thinner and a bit watery, I recommend draining it for an hour or so first. Simply place it into a fine mesh sieve and set over the sink.

Cottage cheese can often taste quite salty so this protein mousse recipe doesn’t call for any additional salt. Once the sweetener, vanilla, and cocoa powder are mixed in, it won’t taste salty or savory.

Protein Options: Although this recipe calls for chocolate whey protein powder, you have plenty of options. Any kind of protein powder (egg white, whey, vegan, etc.) should work here, although plant-based powders tend to have a more earthy flavor.

If you don’t have chocolate protein powder, plain or vanilla can also work. But you will want to add an additional tablespoon of cocoa powder and some additional sweetener. Add those in when you blend the cream cheese.

Sweetener Options: This recipe does not rely on the sweetener for consistency or texture so feel free to use what you like best. It should be a powdered version to avoid any grittiness.
