Dark Chocolate Keto Mousse

The Dark Chocolate Keto Mousse is a velvety, rich dessert that captures the essence of traditional mousse without the sugar by using dark chocolate with at least 70% cocoa, heavy cream, and a low-carb sweetener. The chocolate is gently melted using a double boiler or microwave, then folded into softly whipped cream to create a smooth, creamy, and deeply chocolatey mousse. A touch of vanilla extract enhances the flavor, and each serving stays strictly keto with minimal net carbs, making it ideal for dinner parties or make-ahead treats. Serve this indulgent mousse in elegant glasses topped with unsweetened whipped cream, a few fresh berries, shaved dark chocolate, or a pinch of flaky sea salt for a restaurant-worthy finish.

Ingredients

For the dark chocolate mousse

3 ounces dark chocolate, 70% to 85% cocoa chopped into small pieces
1 cup heavy whipping cream cold, divided
1/4 cup powdered keto sweetener such as monk fruit and erythritol blend, to taste
1 teaspoon pure vanilla extract
1/8 teaspoon fine sea salt

Optional toppings

1/4 cup heavy whipping cream whipped without sweetener for topping
4 berries fresh raspberries or strawberries one or two per serving, optional
1 tablespoon shaved dark chocolate, 70% to 85% cocoa optional
1/8 teaspoon flaky sea salt for sprinkling on top, optional

Instructions

Add the chopped dark chocolate to a small heatproof bowl and set it aside.
Create a gentle double boiler by bringing an inch of water to a simmer in a small saucepan and placing the bowl of chocolate on top, making sure the bottom of the bowl does not touch the water.
Warm the chocolate over low heat, stirring frequently with a spatula until it is just melted and smooth, then remove the bowl from the heat and let the chocolate cool to lukewarm so it is no longer hot to the touch.
Alternatively, melt the chocolate in a microwave-safe bowl using 15 to 20 second bursts on low power, stirring between each burst until smooth, then let it cool to lukewarm.
Pour the cold heavy whipping cream into a large mixing bowl and add the powdered keto sweetener, vanilla extract, and fine sea salt.
Using a hand mixer or stand mixer, whip the cream mixture on medium speed until it reaches soft peaks that hold their shape but still look silky and not stiff.
Transfer about one fourth of the whipped cream into the cooled melted chocolate and stir gently until completely combined to lighten the chocolate.
Scrape the lightened chocolate mixture back into the remaining whipped cream and fold carefully with a spatula until the color is uniform and no streaks remain, taking care not to deflate the cream.
Spoon or pipe the mousse into four small glasses or ramekins, smoothing the tops if desired.
Refrigerate the mousse for at least 1 hour to set and develop a firm yet airy texture.
Before serving, top each mousse with a small dollop of unsweetened whipped cream, a few fresh berries if using, a pinch of shaved dark chocolate, and a light sprinkle of flaky sea salt.
Serve the mousse chilled and store any leftovers covered in the refrigerator for up to 4 days.

Notes

Adjust the sweetness to taste by starting with a little less powdered keto sweetener and adding more as needed, since different sweetener blends vary in intensity. For the best texture, stop whipping the cream as soon as it reaches soft peaks to avoid a grainy or buttery mousse. If you prefer a deeper chocolate flavor with slightly fewer carbs, choose chocolate closer to 85% cocoa and reduce the sweetener slightly to keep the balance. For a dairy-free variation, you can substitute well chilled coconut cream for the heavy cream, but be sure to use only the thick solid portion from a refrigerated can for proper whipping and understand that the flavor will have a light coconut note. Keep portions modest to stay within keto macros, and remember that any fresh berry garnish will add small amounts of carbs.
