Whip the Cream & Sweetener: In a large chilled mixing bowl, beat the heavy whipping cream and powdered sweetener on medium-low speed until it begins to thicken. (Avoid overbeating at this stage.)
Add the Cocoa Powder Add cocoa (or cacao) powder to the bowl and continue mixing until stiff peaks form. You want it fluffy but not buttery, so stop as soon as peaks hold their shape.
Serve & Decorate Spoon or pipe the mousse into 4 small dessert glasses. Add toppings like berries or grated chocolate for an elegant finish.
Chill (Optional) For the best texture, chill for 10–15 minutes before serving.
Notes
Dairy-free option: Substitute the heavy cream with chilled coconut cream for a vegan, lactose-free version.
Flavor variations: Add espresso powder, orange zest, or vanilla extract to customize your mousse.
Storage tip: Keep refrigerated in airtight containers for up to 5 days. Freezing isn’t recommended — it alters the texture.
Serving ideas: Pipe into dessert glasses, layer in a keto trifle, or use as a no-bake pie filling.
