Begin by placing the dark chocolate in a microwave-safe bowl. Heat in the microwave in 15-second intervals, stirring well after each interval, until the chocolate is completely melted and smooth—this should take about 1 to 2 minutes total.

In a blender, combine the cottage cheese, unsweetened cocoa powder, maple syrup or honey, pure vanilla extract, and a pinch of sea salt. Blend on high until the mixture is creamy and smooth, taking about 1 to 2 minutes.

Pour the melted dark chocolate into the creamy cottage cheese mixture in the blender. Blend on medium speed until the chocolate is fully incorporated and the mousse is thick and luscious.

Spoon the luscious mixture into serving glasses or bowls. Cover each one with plastic wrap and refrigerate for at least 30 minutes, allowing the mousse to set and the flavors to meld.

Once chilled, remove the mousse from the refrigerator. Add optional toppings like dark chocolate shavings, fresh berries, or a dollop of whipped cream before serving.
