1. Combine all ingredients in a blender: Add the cottage cheese, unsweetened cocoa powder, maple syrup (or honey), vanilla extract, and salt to a high-speed blender or food processor.

2. Blend until completely smooth: Process the mixture on high speed until there are no visible lumps of cottage cheese. This might take 2-3 minutes, depending on your blender. Scrape down the sides of the blender occasionally to ensure everything is incorporated. The mixture should be thick and creamy, resembling traditional mousse.

3. Adjust consistency if needed: If the mousse appears too thick or isn’t blending smoothly, add milk one tablespoon at a time, blending after each addition, until you reach your desired creamy consistency.

4. Taste and adjust sweetness: Spoon a small amount of the mousse and taste it. If you prefer it sweeter, add another tablespoon of maple syrup or honey and blend briefly to combine.

5. Portion into serving dishes: Divide the mousse evenly among small bowls, ramekins, or dessert glasses.

6. Chill for optimal texture (optional): For the best texture and flavor, cover the dishes and refrigerate the mousse for at least 15-30 minutes before serving. This allows it to firm up slightly and the flavors to deepen.

7. Serve and enjoy: Garnish with your favorite toppings if desired, and serve chilled.
