This mousse hits the sweet spot between effortless and impressive. You’ll get a fluffy texture that feels like a classic mousse, but without eggs or complicated steps.

It’s also easy to scale for a crowd or portion into small cups for built-in portion control. Best of all, it uses pantry-friendly ingredients you probably already have if you’re eating low carb.

Four ingredients you can pronounce—no thickeners or stabilizers.
Low carb and sugar-free, but still genuinely dessert-worthy.
Ready in minutes, with a short chill time to set.
Customizable with simple add-ins like espresso or peppermint.

Ingredients

Heavy whipping cream – 1 cup (cold). This gives the mousse its structure and fluff.
Unsweetened cocoa powder – 3 tablespoons.
Dutch-process cocoa gives a smoother, richer chocolate flavor, but natural cocoa works too.
Powdered keto sweetener – 3–4 tablespoons, to taste. Use a powdered erythritol/monk fruit or allulose blend for a smooth finish.
Vanilla extract – 1 teaspoon. Rounds out the chocolate and makes it taste like dessert.

Optional but helpful: A pinch of fine sea salt to sharpen the chocolate flavor.

You can also add 1–2 tablespoons of cream cheese for extra body if you like a thicker, cheesecake-style mousse.

How to Make It

Cooking process: Overhead shot of the mousse mid-whip in a chilled stainless steel mixing bowl, show

Chill your tools. Pop your mixing bowl and whisk or beaters in the fridge or freezer for 10 minutes. Cold equipment helps the cream whip faster and hold peaks.
Whisk the dry ingredients. In a small bowl, stir together the cocoa powder, powdered sweetener, and a pinch of salt. This prevents lumps later.
Start the whip. Add the cold heavy cream to your chilled bowl.
Beat on medium speed until it thickens slightly and soft peaks begin to form.
Add flavor. Sprinkle in the cocoa mixture and pour in the vanilla. Beat on medium-high until the mousse is thick, smooth, and holds medium to firm peaks. Don’t overbeat or it can get grainy.
Taste and adjust. Add a touch more sweetener if needed and beat briefly to combine.
If it looks too thick, fold in a splash of cream to loosen.
Chill briefly. Spoon into serving dishes and refrigerate for 20–30 minutes to set and develop flavor.
Serve. Top with a dollop of whipped cream, a few sugar-free chocolate shavings, or fresh raspberries if you like.

How to Store

Refrigerator: Cover and store for up to 3 days. It may firm up slightly; stir gently to soften before serving.
Freezer: Freeze in single-serve cups for up to 1 month. Thaw in the fridge for a few hours.
The texture becomes more like semifreddo—still delicious.
Airtight is key: Keep it covered to prevent fridge odors and moisture from affecting the texture.

Common Mistakes to Avoid

Overbeating the cream: If you whip too long, it can turn grainy or start to separate. Stop at medium to firm peaks.
Using granulated sweetener: Granules don’t dissolve well and can leave a gritty texture. Use powdered sweetener.
Warm cream or bowl: Room-temperature cream won’t whip properly.
Keep everything cold for best results.
Skipping the sift: Cocoa clumps easily. Sift or whisk with the sweetener first to avoid lumps.
Heavy hand with add-ins: Liquids like coffee or extracts can thin the mousse. Add a little at a time and re-whip gently.

Variations You Can Try

Mocha Mousse: Add 1 teaspoon instant espresso powder to the cocoa mix for a coffee-chocolate kick.
Peppermint Chocolate: Add 1/4 teaspoon peppermint extract.
Garnish with crushed sugar-free peppermint candy.
Orange Chocolate: Add 1/2 teaspoon orange zest and a few drops of orange extract for a bright, citrusy note.
Chocolate Cheesecake Mousse: Beat 2 ounces softened cream cheese until smooth, then whip in the cream and proceed as directed.
Spiced Hot Cocoa: Add 1/4 teaspoon cinnamon and a pinch of cayenne or chili powder for subtle warmth.
Extra Rich: Fold in 1–2 tablespoons of melted, cooled unsweetened baking chocolate for deeper flavor.
Protein Boost: Whisk 1 scoop unflavored or chocolate keto-friendly protein powder with the cocoa and sweetener. Add a splash more cream if needed.

FAQ

Can I use cocoa powder or should I use baking chocolate?

Both work. Cocoa powder is simple and gives a light, fluffy texture.

Melted unsweetened chocolate makes it richer and denser. If using melted chocolate, let it cool slightly and fold it in near the end.

What’s the best keto sweetener for a smooth texture?

Powdered allulose or a powdered erythritol/monk fruit blend works well. Allulose tends to be the smoothest and least cooling on the tongue.

Avoid granulated sweeteners.

Can I make this dairy-free?

Yes. Use a full-fat coconut cream (chilled) and whip it like heavy cream. Taste and adjust sweetness, as coconut can mute chocolate slightly.

The texture will be a bit denser but still creamy.

Why did my mousse turn grainy?

It’s usually from overwhipping or using granulated sweetener. Stop whipping as soon as it reaches firm peaks, and use powdered sweetener. If it’s slightly grainy, gently fold in 1–2 tablespoons of cream to loosen.

How many carbs are in a serving?

It depends on your sweetener and serving size, but a typical 1/2-cup serving is about 3–4 net carbs when made with unsweetened cocoa, heavy cream, and a zero-calorie powdered sweetener.

Always calculate based on your exact ingredients.

Can I make it ahead?

Yes. It holds well for up to 3 days refrigerated. For the best texture, whip it slightly softer if you plan to chill overnight, as it will firm up in the fridge.

Do I need a stand mixer?

No.

A hand mixer works perfectly, and you can even whisk by hand with a little elbow grease. Just keep everything cold and be patient.

Can I add collagen or protein powder?

Yes, but add it sparingly. Mix it with the cocoa and sweetener first to avoid clumps.

You may need a splash more cream to keep the texture silky.
