Ingredients You’ll Need
To make this Zero Carb Chocolate Mousse Recipe, you’ll only need a few ingredients, but each one plays a crucial role in creating that perfect balance of flavor, texture, and creaminess. These essentials come together to make a dessert that is both satisfying and guilt-free.
- Heavy whipping cream: This is the base of your mousse, providing richness and a creamy texture that melts in your mouth.
- Unsweetened cocoa powder: Adds intense chocolate flavor without any carbs or sugar.
- Powdered erythritol (or preferred zero-carb sweetener): Sweetens the mousse without adding carbs, and powder form blends in perfectly for smoothness.
- Vanilla extract: Enhances the chocolate flavor and adds a warm, aromatic touch.
- Pinch of salt: Balances the sweetness and intensifies the chocolate taste.
- Optional sugar-free chocolate shavings: A beautiful garnish for texture and a little extra chocolate punch.
How to Make Zero Carb Chocolate Mousse Recipe
Step 1: Chill Your Tools
Start by placing your mixing bowl and beaters in the fridge for about 10 minutes. Chilling your tools helps the heavy whipping cream whip up faster and reach that perfect stiff peak consistency necessary for a mousse that’s airy yet firm.
Step 2: Whip the Heavy Cream
Pour the cold heavy whipping cream into your chilled bowl. Beat on medium-high speed until soft peaks form. This ensures your mousse will be light and fluffy rather than dense or heavy.
Step 3: Add Cocoa Powder and Sweetener
Gently sift in the unsweetened cocoa powder to avoid lumps, then add your powdered erythritol. Continue whipping at medium speed, allowing the cocoa and sweetener to fully incorporate and the mixture to thicken further.
Step 4: Flavor with Vanilla and Salt
Add the vanilla extract and a pinch of salt to the mousse. These final touches round out the flavor, balancing the bitterness of the cocoa with warmth and brightness.
Step 5: Whip to Stiff Peaks
Continue beating until stiff peaks form, which means the mousse will hold its shape firmly when you lift the beaters. Be careful not to overbeat, or you might end up with butter!
Step 6: Chill Before Serving
Transfer your mousse into serving dishes and refrigerate for at least 30 minutes. Chilling helps the mousse set beautifully and allows all the flavors to meld together for that perfect, indulgent taste.
How to Serve Zero Carb Chocolate Mousse Recipe

Garnishes
Top your chocolate mousse with sugar-free chocolate shavings for a pretty presentation and a subtle crunch. Fresh mint leaves or a sprinkle of cocoa powder also add a lovely visual contrast and hint of freshness.
Side Dishes
This dessert pairs wonderfully with fresh berries like raspberries or blackberries, which add a tart, juicy bite that perfectly complements the rich chocolate. For something creamy, try a dollop of unsweetened whipped cream on the side.
Creative Ways to Present
For an elevated look, serve the mousse in small glass cups or elegant ramekins layered with crushed nuts or a swirl of sugar-free caramel sauce. You can also pipe the mousse into decorative shapes using a pastry bag for a fun twist that impresses guests.
Make Ahead and Storage
Storing Leftovers
This mousse keeps beautifully in an airtight container in the fridge for up to three days. Keep it chilled and covered to maintain its silky texture and avoid it absorbing other refrigerator odors.
Freezing
While better fresh, you can freeze the mousse for up to one month. Just scoop it into freezer-safe containers. When ready to enjoy, thaw it overnight in the fridge. The texture might soften slightly, but a gentle stir will bring back some of that mousse magic.
Reheating
There’s generally no need to reheat this mousse since it’s best served cold. If you prefer it at room temperature, simply let it sit out of the fridge for 10–15 minutes before serving for a softer, creamier experience.
FAQs
Can I use a different sweetener instead of erythritol?
Absolutely! You can substitute powdered stevia, monk fruit sweetener, or any other zero-carb sweetener you prefer. Just adjust the amount to your taste since sweetness levels vary.
Is it possible to make this mousse dairy-free?
Traditional heavy cream is key for the mousse’s texture, but for a dairy-free version, you might experiment with coconut cream. Keep in mind, the texture and flavor will be different, but still delicious.
How long does the mousse take to set?
It typically sets perfectly after about 30 minutes in the fridge, but for a firmer texture, chilling for an hour or more is ideal.
Can I add alcohol to enhance the flavor?
Yes! A splash of rum or coffee liqueur can add a wonderful depth to your Zero Carb Chocolate Mousse Recipe. Just add it in step 4 along with the vanilla extract.
Is this recipe suitable for keto diets?
Definitely. Since it contains no carbs and uses zero-carb sweeteners, this mousse is perfect for keto and low-carb lifestyles, fitting your macros without sacrificing flavor.
