In a blender or food processor, combine the cottage cheese, chocolate protein powder, and espresso powder. Blend until smooth, about 1-2 minutes.
In a large bowl, combine the heavy cream, sweetener, cocoa powder, and vanilla extract. Beat together with an electric mixer until the cream holds stiff peaks, about 3-5 minutes.
Add the cottage cheese mixture to the whipped cream, gently folding together with a spatula to avoid deflating the peaks as much as possible.
Divide the mixture between 4 dessert glasses and chill until it firms up, 1 to 2 hours.
