Step 1: Blend the base ingredients
Add the cottage cheese, cocoa powder, sweetener, and vanilla extract to a blender or food processor
Blend on high until completely smooth and creamy — this should take about 1 minute
Scrape down the sides as needed to ensure everything is fully mixed

Step 2: Add optional chocolate
If using melted dark chocolate, pour it into the blended mixture
Pulse again until the chocolate is fully incorporated into the mousse

Step 3: Chill the mousse
Transfer the mousse to individual jars or dessert bowls
Refrigerate for at least 30 minutes for the best texture and flavor

Step 4: Garnish and serve
Top with your favorite low-carb garnishes — a sprinkle of cocoa powder, a few berries, or a dusting of shaved chocolate
Serve chilled and enjoy every creamy, chocolatey spoonful
