Toss the cottage cheese, cocoa powder, and sugar-free maple syrup into a blender. Blend on high until the mixture is completely smooth and creamy. You might need to scrape down the sides once or twice to make sure everything is well incorporated.

Pour the mousse into individual serving dishes or a big bowl and let it chill in the fridge for at least an hour. This step is crucial—it lets the flavors meld together and gives the mousse that perfect, spoonable texture.

Once chilled, top it with a bit of whipped cream, some fresh berries, or a sprinkle of chocolate shavings.
