Heat the heavy cream in a small saucepan until it just starts to steam. Remove from the heat, add the chopped dark chocolate, and let it sit for 2 minutes, then stir until completely smooth.
Add the cottage cheese to a blender and blend on high for 1 to 2 minutes, scraping down the sides once, until it is perfectly smooth with no curds left.
Add the cocoa powder, powdered allulose, vanilla extract, salt and the melted chocolate mixture to the blender. Blend for another 30 seconds until thick, glossy and fully combined.
Pour the mixture into a loaf pan, smooth the top and freeze for 1 hour.
Stir the semi-frozen mixture well, scraping the edges into the center, then fold in the chocolate chips and smooth the top again.
Cover and freeze for 3 to 4 more hours, until firm and scoopable.
Let the ice cream sit at room temperature for 10 to 15 minutes before scooping for the creamiest texture.
