For the smoothest texture, use powdered rather than granular erythritol so it dissolves completely into the cream. If you prefer a stevia-based sweetener, start with a very small amount and add more to taste, since stevia is significantly sweeter than erythritol. This mousse keeps well covered in the refrigerator for up to 3 days, making it ideal for make-ahead desserts or portioned snacks. To lower carbs even further, skip the optional whipped cream topping and chocolate shavings or use them sparingly. Each serving is designed to stay within strict keto macros while still feeling indulgent and satisfying.
